Several database files, supplied by IBP, are required by this system:
A species code authority file defines the various codes for kinds of birds. See Section 2.1, “MAPS species code authority file (2004)”, Section 2.2, “MAPS species code authority file (1998)”, and Section 2.3, “MAWS species code authority file”.
A station codes authority file defines the individual banding stations, and groups them into locations. See Section 2.4, “MAPS stations authority file” and Section 2.5, “MAWS stations authority file”.
The file describing species codes (and codes for
subspecies and more generic forms as well) is represented
as a dBASE V .dbf file.
The current version of this file is named SPCODE04.DBF, for year 2004.
Here is a table showing the dBASE V names of these fields, their field types, and their contents.
