It contains information about a named feature such as location, origin of feature name, etc. The Gazetteer Table contains one row for each feature named on Venus. The table is formatted so that it may be read directly into many data management systems on various host computers. All fields (columns) are separated by commas, and character fields are preceded by double quotation marks. Each record consists of 372 bytes, with a carriage return/line feed sequence in bytes 371 and 372. This allows the table to be treated as a fixed length record file on hosts that support this file type and as a normal text file on other hosts."

This name is stored in upper case only so that it can be used for sorting and search purposes. This field should not be used to designate the name of the feature because it does not contain the diacritical marks.
