GLOSSARY

 

Archive – An archive consists of one or more data sets along with all the documentation and ancillary information needed to understand and use the data. An archive is a logical construct independent of the medium on which it is stored.

Archive Volume – A volume is a unit of media on which data products are stored; for example, one CD-ROM or DVD-ROM. An archive volume is a volume containing all or part of an archive; that is, data products plus documentation and ancillary files.

Archive Volume Set – When an archive spans multiple volumes, they are called an archive volume set. Usually the documentation and some ancillary files are repeated on each volume of the set, so that a single volume can be used alone. 

Virtual Archive Volume – When an archive is available online, it is not constrained by the size limitations of physical media and it is called a virtual archive volume.  The virtual archive mimics the directory structure of a single archive volume, with an expanded data directory to contain all of the data available on the archive volume set.

Catalog Information – Descriptive information about a data set (e.g. mission description, spacecraft description, instrument description), expressed in Object Description Language (ODL) which is suitable for loading into a PDS catalog.

Data Product – A labeled grouping of data resulting from a scientific observation, usually stored in one file. A product label identifies, describes, and defines the structure of the data. An example of a data product is a planetary image, a spectrum table, or a time series table.

Data Set – An accumulation of data products. A data set together with supporting documentation and ancillary files is an archive.

Standard Data Product – A data product generated in a predefined way using well-understood procedures, processed in "pipeline" fashion. Data products that are generated in a non­standard way are sometimes called special data products.

 


1. Introduction

1.1 Purpose and Scope

This Software Interface Specification is intended to be used by those who wish to understand the format and content of the THEMIS Archive.  Typically, these individuals would be software engineers, data analysts, or planetary scientists.           

The specifications in this document apply to all THEMIS standard product archive volumes that are generated by the Mars Odyssey Project.

1.2 Content Overview

This Software Interface Specification (SIS) describes the content, generation, and format of the THEMIS data aArchive.  THEMIS is a combination visible (VIS) and infrared (IR) multi-spectral imager onboard the 2001 Mars Odyssey Orbiter.  The data products include a variety of raw, calibrated and derived products presented in both raw raster and geographically projected coordinates.  The complete data archive is delivered as two related archive volume sets: Mars Odyssey THEMIS Standard Products and Mars Odyssey THEMIS Projected Products.  The THEMIS Team at the ASU Mars Space Flight Facility is responsible for generating these products and assembling the archive.

All products presented in raw raster (as collected) order are archived in the Mars Odyssey THEMIS Standard Products (ODTSDP) volume set.  The standard data products in the archive are the raw (EDR) and, the calibrated (RDR) spectral image QUBEs, and either a visible apparent brightness image (ABR) or an infrared brightness temperature image (BTR) derived from the RDR QUBE.  All products are available at both visible andor thermal infrared wavelengths: VISEDR or IREDR, VISRDR or IRRDR, and VISABR or IRBTR.  In this text, the acronyms THM-EDR and THM-RDR may be used to collectively reference the raw and calibrated data products at both wavelengths. 

All products presented in geographically projected coordinates are archived in the Mars Odyssey THEMIS Projected Products (ODTGEO) volume set.  The special data products in this archive are the projected and calibrated (GEO) spectral image CUBEs, available at both visible and thermal infrared wavelengths, and collectively referenced in the text as THM-GEO.  The available derived infrared products include projected brightness temperature images (PBT) and decorrelation stretch browse images (DCS).  The available derived visible products include projected albedo images (ALB) and false color composite browse images (RGB).  All products in the ODTGEO archive were generated from the corresponding RDR QUBE in the ODTSDP archive.Geometrically projected spectral images and derived products are available as special, non-standard data products generated from the RDR QUBE. The THEMIS Team at the ASU Mars Space Flight Facility is responsible for generating these products and assembling the archive.

1.4 Relationships with Other Interfaces

This Archive Volume SIS could be affected by changes to the design of the THEMIS standard data products or the THEMIS processing software, described respectively in the THEMIS Software Interface Specification [8], and in the THEMIS Processing User’s Guide [9], and in the THEMIS Geometric Processing User’s Guide [10].

2. Archive Volume Contents

This section describes the contents of the THEMIS archive volumes, including the file names, file contents, file types, and organization responsible for providing the files.  The two archive volume sets are organized with a similar directory structure, as described below; details for each archive volume are shown in Appendices A & B.  Each archive volume contains the data products from a single publication release period (typically, three months of data collection) and is named using the appropriate RELEASE_ID.

Data from the six THEMIS standard datasets (IREDR, VISEDR, IRRDR, VISRDR, IRBTR, and VISABR) are stored in separate archive volumes;  however, each volume has a similar directory structure, as described below and shown in Appendix A.

THEMIS archive volumes will be available on physical media only for permanent archive purposes,purposes and available online for public consumption (details in section 4).  The online archive,  also referred to as the “virtual volume”, is a logical volume based on the format of the physical archive, with minor differences due to the size limitations of the latter.  The format of the online virtual archive  is described in Appendix CB.

Pattern placeholder abbreviations are used repeatedly throughout the next few sections; for example, release subdirectories follow the pattern odtPPP_vxxxx, data subdirectories follow the pattern AoooXXPPP, and data product filenames follow the pattern AooooonnnPPP.EXT.  Use this key to interpret their meanings:

            A            is a 1 letter description of the type of image collected; 

                                    [ V = visible image;  I = infrared image; ]

            oooXX    is the first three digits of a mission orbit number for one-hundred orbit directory;

                                    [ 010XX includes all orbits between 01000 and 01099 ]

            ooooo     is a 5-digit mission orbit number when the image was collected; 

                                    [ 01234 = mapping orbit number example ]

            nnn         is a 3-digit image sequence number indicating the order that images were collected each orbit;  [ 001 =  first image collected in the ooooo orbit ]

            PPP        is a 3-letter suffix uniquely identifying the product type;

                                    [ example EDR ]

            vxxxx     version number and release number identifies this volume in the volume set;

OR      v_xxxx            [ 2_0001 = version 2, release_id=0001 ]

 

2.1 Root Directory Contents

Files in the Root directory include an overview of the archive, a description of the volume for the PDS Catalog, and a list of errata or comments about the archive.  All files in this directory are provided by the THEMIS team.  The following files are contained in the Root directories of both the ODTSDP and ODTGEO archive volumesy.

ODTGEO

ODTDCSv_xxxx

Includes up to four DCS images for each qualified IR-RDR; image subdirectories follow pattern IoooXXDCS

ODTGEO

ODTRGBv_xxxx

Includes one RGB image for each qualified VIS-RDR; image subdirectories follow pattern VoooXXRGB

 

Individual browse and thumbnail images are contained in the data subdirectories and haveBrowse image filenames are based on the PRODUCT_ID of the data product that they represent.  The names follow the pattern of Aooooonnn.png, where

            A         is a 1 letter description of the type of image collected;  [ V = visible image;  I = infrared image; ]

            ooooo  is a 5-digit mission orbit number when the image was collected;  [ 01000 = mapping orbit number example ]

            nnn      is a 3-digit image sequence number indicating the order that images were collected each orbit;  [ 001 =  first image collected in the ooooo orbit ]

            .png     in a 3-letter extension describing this product as a PNG file.

Each browse image has the same dimensions (samples by lines) as a single band of the source data product.  Infrared browse images are usually derived from the data collected in band 9 (centered at 12.57 mm) of the source IRRDR product;.  vVisible browse images are usually derived from the data in band 3 (centered at 0.654 mm) of the source VISRDR product, then geographically projected.  If the named band is not available in the source product the first available band, in numerical order, is used to create the browse image.  Note that there are no browse images for infrared reset (R-RDR) or infrared shutter (S-EDR) images.

Thumbnail images are browse images reduced to 10% of the original file size.  Thumbnail image names follow the pattern of Aooooonnn_small.jpg, with “A”, “o”, and “n”as  defined as above.

 

Individual browse and thumbnail images are contained in subdirectories following the same organizational conventions of the Data subdirectories which they represent (see Section 2.5).  The file in this directory is provided by the THEMIS team.  The following files are contained in the Browse directory.

2.5 Data Directory Contents and Naming

The Data image subdirectories contain the data products as appropriate for the archive volume.  The overview files in this directory are provided by the THEMIS team.  The following files are contained in the Data directory of both the ODTSDP and ODTGEO archive volumes.

Data File Name

File Contents

DATAINFO.TXT

A description of the contents of this directory; the contents of this file varies on each of the archive volumes

 

The Data directory is organized into release volume subdirectories named for the dataset included and the volume name.  These, in turn, contain image subdirectories that follow the pattern AoooXXPPP (see pattern key above) and include 100 orbits of image data.  The size of the image subdirectories will vary between each archive volume due to inconsistent data volume collected during any given block of orbits.  All files and standard data products in the Data directory of the ODTSDP and ODTGEO archive volumes are provided by the THEMIS team.

The following subdirectories are contained in the Data directory of the ODTSDP archive volume.  A detailed description of the data products is available in the THEMIS Software Interface Specification [8]. The Data directory contains data subdirectories and related overview files;  the THEMIS standard data products (see THEMIS Standard Data Product SIS [8]) are stored in the data subdirectories.  The number of subdirectories on an archive volume will maximize the storage space of the archive media, but will vary between individual volumes due to the inconsistent data volume over any given block of orbits. 

The data subdirectories contain the image data products in groups of 10 orbits.  For raw infrared volumes, a calibration image from an orbit outside of the range of the 10-orbit subdirectories may be duplicated on the volume that contains the IR image that requires that calibration image. The subdirectories are named for the data contents following the pattern of “AoooXXPPP” where

            A         is a 1 letter description of the type of image collected;  [ V = visible image;  I = infrared image;  R = infrared reset image;  S = infrared shutter image ]

            ooo      is the first 3 numbers of the mission orbit number when the data was collected, zero padded

            XX       is a placeholder representing the remaining digit of the mission orbit number

            PPP     is a 3 letter description of the processing level of the data products;  [ ABR = VIS apparent brightness image; BTR = IR brightness temperature image; EDR = raw data;  RDR = radiometrically calibrated data  ]

A detailed description of the data products is available in the THEMIS Software Interface Specification [8]. 

All files and standard data products in this directory are provided by the THEMIS team. The following files are contained in the Data directory or the indicated subdirectory.

3. Archive Volume Format

This section describes the format of THEMIS Archive Volumes. Data that comprise the archive will be formatted in accordance with Planetary Data System specifications (PDS Data Preparation Work­book, [4] and PDS Standards Refer­ence, [5]).

3.1 Disk Format

Archive Volumes have a digital versatile disk (DVD) format that is compatible with the computer operating systems MS‑DOS, Macintosh, and SunOS. The volume format is in accordance with ISO 9660 level 2 Interchange Standard [6].

3.2 File Formats

This section describes file formats for the kinds of files contained on Archive Volumes.

 3.2.1 PDS Label Format

All text and data files in the archive have PDS labels associated with them, either embedded at the beginning of the file or detached in a separate file;  the label location is described in each of the following individual “file format” sections.  For examples of PDS labels for each type of data product, see the THEMIS Standard Data Product SIS [8].

            A PDS label, whether embedded or detached from its associated file, provides descriptive information about the associated file.  The PDS label is an object-oriented structure consisting of sets of 'keyword=value' declarations.  The object to which the label refers (e.g. IMAGE, TABLE, etc.) is denoted by a statement of the form:

                        ^object = location

in which the carat character (^, also called a pointer in this context) indicates where to find the object.  In an embedded label, the location is an integer representing the starting record number of the object (the first record in the file is record 1).  In a detached label, the location denotes the name of the file containing the object, along with the starting record or byte number, if there is more than one object in the file. For example:

                        ^HEADER = ("F01.IMG",1)

                        ^IMAGE = ("F01.IMG",1025 <BYTES>)

indicates that the IMAGE object begins at byte 1025 of the file F01.IMG, in the same directory as the detached label file.  Below is a list of the possible formats for the ^object definition.

                        ^object = n

                        ^object = n<BYTES>

                        ^object = "filename.ext"

                        ^object = ("filename.ext",n)

                        ^object = ("[dirlist]filename.ext",n)

                        ^object = ("filename.ext",n<BYTES>)

                        ^object = ("[dirlist]filename.ext",n<BYTES>)

where

                     n             is the starting record or byte number of the object, counting from the beginning of the file (record 1, byte 1),

                     <BYTES>         indicates that the number given is in units of bytes,

                     filename            is the up to 8 character, alphanumeric upper‑case file name,

                     ext          is the 3 character upper‑case file extension,

                     dirlist    is a period‑delimited path‑list of parent directories, in upper case, that specifies the object file directory (used only when the object is not in the same directory as the label file).  The list begins at the directory level below the root directory of the DVD.  '[dirlist]' may be omitted when the object being described is located either in the same directory as the detached label, or in a subdirectory named LABEL that is located in a higher level of the directory tree, typically the DVD root itself.

            Lines of text in detached labels end with a carriage return character (ASCII 13) and a line feed character (ASCII 10).  This allows the files to be readable under various operating systems.

 3.2.2 Document File Format

Document files with the .TXT suffix exist in the Root, Browse, Catalog, Data, Document, and Index directories.  They are ASCII files which have embedded PDS labels.  Lines in a .TXT file end with a carriage return character (ASCII 13) and a line feed character (ASCII 10). This allows the files to be readable under various operating systems.

Documents in the Document directory may contain formatting and figures that cannot be rendered as ASCII text.  Therefore, each document is given in two formats, hypertext and PDF, and is accompanied by  a detached PDS label.  The hypertext file contains ASCII text plus hypertext markup language (HTML) commands that enable it to be viewed in a Web browser such as Netscape Navigator or Microsoft Internet Explorer.  The hypertext file may be accompanied by ancillary files such as images and style sheets that are incorporated into the document by the Web browser.  The second format, PDF (Portable Document Format) is a proprietary format of Adobe Systems Incorporated that is frequently used for distributing documents.  Adobe offers free software, Acrobat Reader, for viewing PDF files.

 3.2.3 Catalog File Format

            Catalog files (suffix .CAT) exist in the Root and Catalog directories.  They are ASCII text files with an embedded PDS label.  The text contents are formatted in an object-oriented structure consisting of sets of 'keyword=value' declarations.  Lines in a .CAT file end with a carriage return character (ASCII 13) and a line feed character (ASCII 10).  This allows the files to be readable under various operating systems.

 3.2.4 PNG and JPG File Formats

THEMIS browse images are stored as PNG and JPEG files (.jpg suffix) in the Browse subdirectories.  PNG and JPG images are 24-bit per pixel, color images in binary format.  The THEMIS team uses the standardized image compression algorithms to create the browse files.  For more information see http://www.libpng.org/pub/png  and http://www.jpg.org. 

 3.2.5 IMAGE File Format

THEMIS brightness records are single band images stored as IMAGE files (.IMG suffix) in the Data subdirectories.  All THEMIS IMAGEs adhere to the PDS standards for IMAGE objects as defined in the PDS Standards Reference [4].  Each IMAGE is composed of a header and a binary array of data derived from radiometric calibration of one observation.  Each IMAGE header includes the embedded, ASCII PDS label, with information stored as ASCII text in a “keyword = value” format compliant with PDS standards. 

For more information about the format and content of these data products, see the THEMIS Data Product SIS [8].

 3.2.6 Tabular File Format

Tabular files (.TAB suffix) exist in the Index directory.  Tabular files are ASCII files formatted for direct reading into many database management systems on various computers.  All fields are separated by commas, and character fields are enclosed in double quotation marks (").  (Character fields are padded with spaces to keep quotation marks in the same columns of successive records.)  Character fields are left justified, and numeric fields are right justified.  The "start byte" and "bytes" values listed in the labels do not include the commas between fields or the quotation marks surrounding character fields.  The records are of fixed length, and the last two bytes of each record contain the ASCII carriage return and line feed characters.  This allows a table to be treated as a fixed length record file on computers that support this file type and as a text file with embedded line delimiters on those that don't.

            All tabular files are described by PDS labels, either embedded at the beginning of the file or detached.  If detached, the PDS label file has the same name as the data file it describes, with the extension .LBL; for example, the file INDEX.TAB is accompanied by the detached label file INDEX.LBL in the same directory.

 3.2.7  QUBE File Format

THEMIS raw and calibrated data are multispectral images stored as QUBE files (.QUB suffix) in the Data subdirectories.  All THEMIS QUBEs adhere to the PDS standards for SPECTRAL_QUBE objects as defined in the PDS Standards Reference [4].  Each QUBE is composed of a header and a binary array of data collected during one observation.  

Each QUBE header includes the embedded, ASCII PDS label and a HISTORY data object;  raw infrared (IR-EDR) data products also contain a telemetry (TLM) data table.  The HISTORY object is a cumulative record of all the computer manipulations of the data file.  The information is stored as ASCII text in a “keyword = value” format similar to, but not intended to be compliant with, PDS standards.  The TLM table follows the PDS standards for a binary table of fixed-length records, and is accompanied by a detached PDS label (TLM.FMT) that defines the table structure.

For more information about the format and content of these standard data products, see the THEMIS Data Product SIS [8]. 

 3.2.8 CUBE File Format

THEMIS projected products are multispectral images stored as ISIS CUBE files (.CUB suffix) in the Data subdirectories.  The THEMIS CUBE files themselves are not PDS compliant, however each image CUBE is associated with a PDS detached label following the standards defined in the PDS Standards Reference [4].  Each CUBE is composed of a header, a binary array of data collected during one observation, and a history object.  For more information about the format and content of these projected data products, see the THEMIS Geometry Processing User’s Guide [10]. 

 

4. Archive Volume Generation

4.1 Interface Media Characteristics

All archive volumes in the THEMIS Standard Product Archive conform to the ISO 9660 standards (ISO 9660-1988, [6]).

4.2 Labeling and Identification

The THEMIS data archive is compliant with the PDS Standards Reference [4] for the VOLUME_SET, VOLUME_ID, and DATASET_ID values used to identify the archive.  All THEMIS archive volumes are part of the “Odyssey Mission to Mars” VOLUME_SERIES.

The THEMIS data products are delivered in one of two related archive volume sets, commonly referred to throughout this document as ODTSDP and ODTGEO.  Each volume set will be divided into smaller volumes which include only the data collected during a specific time range (typically three months) and delivered as part of a single release; the RELEASE_ID (xxxx) is used in name of the VOLUME_ID.

Each of the archive volume sets includes multiple THEMIS data products.  The following THEMIS data sets are available on the archive volume set indicated.As per the PDS Standards Reference [4], each THEMIS archive volume will bear a VOLUME_ID based on the last two components of the VOLUME_SET_ID.  The VOLUME_SET_ID is USA_NASA_PDS_ODTdsv_xxxx, where

            OD      identifies this volume set with the Mars Odyssey spacecraft

            T          identifies this volume set with the THEMIS instrument

            dsv       identifies the THEMIS DATA_SET_ID and the version number of the data  set

For example, the first volumes in the original data release [v = 0] have the VOLUME_ID values of ODTIE0_0001, ODTVE0_0001, ODTIR0_0001, ODTVR0_0001, ODTIB0_0001, and ODTVB0_0001 for each data set respectively.  The data available on  each volume will maximize the space available, as described in Section 1.3;  no attempt will be made to correlate the data in a given volume number (e.g. ODTIE0_9999) with the same volume number of another  volume set ( e.g. ODTIR0_9999).    

4.3 Data Product Sizes and Delivery Rates

The size of individual raw data products (VISEDR & IREDR) depends on several factors: image type (VIS vs. IR), length of an image (# frames), and the number of bands in the image.  Within these parameters, a raw VIS image (VISEDR) can vary in size from 0.38 to 3.7 Mbytes;  a raw IR image (IREDR) can vary in size from 0.07 to 199 Mbytes.  Calibration (VISRDR & IRRDR) increases the file size approximately by a factor of two, as compared to the corresponding raw image;. projection (VISGEO & IRGEO) increases the file size approximately by a factor of four, as compared to the corresponding raw image.

The estimated total volume of data to be collected over the course of the mission is limited by the available downlink allocated to THEMIS.  Many factors affect the actual downlink available on any given day, which can vary from 0 to 375 Mbytes per day.  THEMIS mission planners will maximize data collection by balancing the day’s available allocated downlink against the size-defining parameters of the daily planned observations (VIS/IR, image length, number of bands). 

For example, the following shows the expected content range of the 100 orbit data subdirectories over the course of the mission, taking into account the primary variables affecting file size and data  volume.

4.4 Data Transfer and Validation Methods

In compliance with the Odyssey Archive Plan [2], the THEMIS Team will produce complete THM-EDR, THM-RDR, IR-BTR, and VIS-ABR Standard ProductODTSDP and ODTGEO Archive Volumes at the ASU Mars Space Flight Facility.  Archive volumes will be written as necessary to write-once DVDs (DVD-Rs) for distribution to co-investigators and the Science Data Validation Team (SDVT).  The PDS Imaging Node will receive a DVD copy of each archive volume to verify that it conforms to the THM Standard Data Product SIS [3] and to PDS standards for archive volumes. 

Upon approval of a volume by the SDVT, the THEMIS Team will make the volume available online for public consumption (see Appendix B).  For archive purposes, the THEMIS Team will generate three DVD copies of each volume and deliver them copies to the permanent archive sites: PDS Imaging Node, PDS Central Node, and the National Space Science Data Center (NSSDC)..  THEMIS will make additional copies for the Mars Odyssey Project of a volume by special request only.

Appendix A: ODTSDP Archive Volume Directory Structure

Below are the directory structures of the THEMIS ODTSDP archive volumes.  There are six THEMIS archive volume sets corresponding to the six THEMIS datasets included on each archive volume: IREDR, VISEDR, IRRDR, VISRDR, IRBTR, AND and VISABR.  Each archive volume contains the data products published during a single release (usually three months of data collection); the RELEASE_ID is used as the “xxxx” part of the VOLUME_ID.  In the structure below, nNames without extensions are directory names (e.g. CATALOG), while names with extensions are file names (e.g. CATINFO.TXT).  Lowercase letters in names are placeholders for numbers described in Sections 2.02 and 2.5 of the main text.

Appendix B: ODTGEO Archive Volume Directory StructureTHEMIS Virtual Archive Volume

Below are the directory structures of the THEMIS ODTGEO archive volumes.  There are four datasets and two browse data collections included on each archive volume: IRGEO, VISGEO, IRPBT, VISALB, IRDCS, and VISRGB.  Each archive volume contains the data products published during a single release (usually three months of data collection); the RELEASE_ID is used as the “xxxx” part of the VOLUME_ID.  In the structure below, names without extensions are directory names (e.g. CATALOG), while names with extensions are file names (e.g. CATINFO.TXT).  Lowercase letters in names are placeholders for numbers described in Section 2.0 of the main text.

Appendix C: THEMIS Virtual Archive Volume

 

A.1 Virtual Archive Volume Contents

In compliance with the Odyssey Archive Plan [2], and as discussed in Sections 4.3 and 4.40 above, THEMIS standard data products will be made available online from the PDS THEMIS Sub Node (http://themis-data.asu.edu).  The THEMIS Virtual Archive is composed of  twoa very large PDS logical volumes, containing all six of theall of the THEMIS datasets.  Although the overall structure of the Virtual Archive mimics the directory structure of the individualsingle archive volumes described in the body of this text, there are severalare a few significant differences to be noted.

1.         The DATA directory in each logical volume includes the release subdirectories from all of the archive volumes.  The same release subdirectory naming convention established on the archive volumes (see Section 2.5) is maintained in the virtual volume. 

2.         The BROWSE directory in each logical volume includes the release subdirectories from all of the archive volumes. The same release subdirectory naming convention established on the archive volumes (see Section 2.2) is maintained in the virtual volume.

3.         A logical volume VOLDESC.CAT files will be available at the root level describing all the data in the virtual volume.  The volume catalogs from the individual archive volumes (VOLDESC_vxxxx.CAT) are available in special subdirectory (VOLDESC/) within the DATA directory. 

1.              The DATA directories are first divided into dataset directories, named according to the archive VOLUME_ID naming convention  (see Section 4.2), with x’s used as placeholders for the volume numbers.  Within these dataset directories are image subdirectories which contain data products in groups of 100 orbits.  As on the archive volumes, the image subdirectories are named following the pattern AoooXXPPP (see Section 2.5 for the pattern definition).   

1.              The BROWSE directory is divided into image subdirectories of 100 orbits, similar to the IRRDR and VISRDR DATA subdirectories from which the browse products were derived. 

1.              Both infrared and visible calibration files are available in the CALIB directory.

1.              A logical volume VOLDESC.CAT will be available at the root level for all data in the virtual archive volume.  Individual logical volume objects (ODTaaVOL.CAT) are available within the DATA-dataset directory;  these are equivalent to the VOLDESC.CAT files on the individual archive volumes.

1.              All six dataset files (ODTIBDS.CAT, ODTIEDS.CAT, ODTIRDS.CAT, ODTVBDS.CAT, ODTVEDS.CAT, and ODTVRDS.CAT) and all six release catalogs (ODTIBREL.CAT, ODTIEREL.CAT, ODTIRREL.CAT, ODTVBREL.CAT, ODTVEREL.CAT, and ODTVRREL.CAT) are available in the CATALOG directory.

4.         All index information for the dataset is included in the INDEX_ODTaa.TAB, THMIDX_IR.TAB, and THMIDX_VIS.TAB filesOFor simplicity, only the cumulative indexes are available in the top level of the INDEX directory;  a VOL_INDEX/ subdirectory has been added to contain a copy of the individual archive volume index files.

1.              A GEOMETRY directory has been added containing the geometrically registered images and their associated files;  see Appendix C for more information about these data products. 

BBelow is the directory structure of the THEMIS Vvirtual Aarchive Vvolume.;  lowercase o’s are used as placeholders for the first 3-digits of the orbit number in image subdirectories names.  All directory and file names listed below are case insensitive.; o’s and n’s Lowercase letters in names are placeholders for numbers described in Section 2.0 of the main text are used to represent orbit numbers and image numbers respectively.

Appendix D: ODTGEO Version-1 Archive Volume

At the time of the original release of the THEMIS GEO products, all data was included in a single archive volume with the projected products under the GEOMETRY subdirectory.  The upgrade to Version-2 of the THEMIS GEO products was initially released concurrent with the split of the two archive volumes (ODTSDP and ODTGEO), and the two volumes were reorganized to mirror each other.  Available ODTGEO Version-1 volumes still maintain the directory structure of the original volumes, and include the original documentation that describeds that structure.  Below is an outline of the directory structure of the ODTGEO_1xxxx archive volumes; lowercase letters in names are placeholders for numbers described in Sections 2.02 and 2.5 of the main text.

THEMIS Geometrically Registered Products

Geometry Product Overview

Geometrically registered (GEO) multi-spectral images are made available in the virtual archive volume as special data products.  The images are generated by geometrically projecting THEMIS infrared and visible radiance products (IR-RDR and VIS-RDR QUBEs) using the ISIS software (http:// isis.astrogeology.usgs.gov/Isis2/isis-bin/isis.cgi).  The resulting projected radiance image maintains the standard ISIS multispectral CUBE format, including an attached label.  Geometric parameters, such as latitude and longitude, are calculated from the image for each corner and the center point then stored in index tables (thmidx_ir.tab or thmidx_vis.tab, Section 2.7). 

For selected THEMIS images special derived products are generated from the geometrically projected images.  For infrared images these products may include projected brightness temperature (IR-PBT) records and decorrelation stretched (IR-DCS) images.  Browse images (Section 3.2.4) are provided to easily view the projected products.

THEMIS projected products are named following a pattern similar to that established for the standard data products Aooooonnnggg.ext, where the processing level “ggg” is an abbreviation representing the geographic processing applied to the image, and the “ext” is the extension appropriate for the product type (Section 3).  A detached PDS label (Aooooonnnggg.lbl, as per Section 3.2.1) is available with each GEO image and includes the cumulative processing history for the image. 

A detailed description of the data processing and special image products is available in the Mars Odyssey THEMIS: Geometric Processing User’s Guide [10].

A.1 Geometry Directory Contents

The Geometry directory contains data subdirectories, related overview files, and documentation.  The data subdirectories contain the geometrically registered image data products, the associated PDS labels (where available), and projected browse images.  As with the other image directories in the virtual archive volume, the subdirectories are divided in groups of 100 orbits and named following the pattern AoooXXPPP (see Appendix A or B).  All files in this directory are provided by the THEMIS team.  The following files are contained in the Geometry directory, unless otherwise noted.
