@(#)README 4.4 93/09/26 GIE REL" The files in this directory are support data for PROJ.4 programs as well as test scripts for testing proj installation. File Contents: README --- This file proj_def.dat --- basic default file used by proj. epsg --- Translation of EPSG GCS/PCS codes into PROJ.4 via init= mechanism. epsg-deprecated --- EPSG definitions that have been deprecated. They are not part of 'epsg' anymore, but may have been delivered with earlier versions of 'epsg'. Thus, they might occur e.g. in WMS (Web Mapping Services) running with old EPSG definitions. This file is not complete at all - it contains just definitions that were individually reported. nad27 --- North American Datum 1927 for "init=" definition of State Plane Coordinate Systems (SPCS). nad83 --- North American Datum 1983 for "init=" definition of SPCS. GL27 --- Great Lakes Survey grids, NAD27 world --- Proj specifications for several international grid systems. nad.lst --- Reference list of SPCS States and NGS datum identifiers IGNF --- Translation of French Mapping Agency codes into PROJ.4 via init= mechanism. nad2bin.c --- C program to convert above ASCII files into binary files usable by program nad2nad. Compiled and used in install script only. install --- Unix shell (sh) script to install nad2nad file and proj init files. Read beginning for usage instructions. test27 --- Unix shell (sh) scripts to test installation of test83 proj and nad27/nad83 init files. These scripts expect release 4 proj to reside in ../src. pj_out27 --- Comparison files for above test procedures. pj_out83 The following NADCON conversion files are distributed in separate, uncompressed distibution file(s).
