Unless other- wise noted, each is archived with its root directory the same name as the part of the file name preceding the -. The ?.? part of the file name represent respective version and release numbers (occasionally, sub-release numbers are given that represent bug fixes). README this file. PROJ.4.?.tar.Z Release 4 of cartographic projection software. Replaces proj-3.*. Code ANSI and (probably) POSIX compliant. Procedure libraries for "roll-your-own" programs. Includes program proj (AKA invproj) that provides forward projections for about 80 cartographic projections and inverse conversions for more that 50% of the forward procedures. Control files are provided for State Plane Coordinate System (SPCS) conversions to and from geographic coordinates. Also included is a forward/inverse geodesic program for an elliptical earth. Reference: "Cartographic Projection Procedures for the Unix Environment--A User's Manual", G.I.Evenden, USGS Open-File Report 90-284, 1990, 63p. (see proj.OF90-284.ps) plus the following supplement. PROJ.4.?.ps.Z Intermim documentation of release 4 proj. Use as a supplement to OF 90-284 (listed above). PostScript for 300dpi, black-on-white printers. proj.OF90-284.ps directory of PostScript files to create proj's OF doc- umentation on a 300bpi, black-on-white laser printer. PROJ.4.?.A.tar - Supplementary NADCON tables for nad2nad program. NOTE: use ftp "binary" mode when getting this file. It contains compressed files. DOS-PROJ.4.?.? - uncompressed directory of PROJ.4 for PC/MS-DOS. Load 'n go version. PKZIP of sources. Crude docs. graphics-?.?.tar.Z Device independent vector graphics system employed by MAPGEN/PLOTGEN programs. Reference: "Technical Manual for a UNIX-based Device-Independent Vector Graphic System," G.I.Evenden, USGS Open-File Report 91-2, 1991, 35p. mapgen-?.?.tar.Z MAPGEN/PLOTGEN system for plotting geographic and other data. Requires pre-installed 'proj' and 'graphics'. Reference: "User's Manual for MAPGEN (UNIX version): a method of transforming digital cartographic data to a map,", G.I. Evenden, J.M. Botbol, USGS Open-File Report 85-706, 58p. Out of date but provides basic operational concepts of the system. Refer to current 'man' files for modern usage. xzoom-?.?.tar.Z X11R4 previewer of MAPGEN/PLOTGEN graphic data. Root directory "mapgen/xzoom" and should be loaded as part of mapgen directory structure. LaTeX manual in distribution. Sorry, no man file. coast directory containing WDB-II coastline files in MAPGEN *coast* program format. grph.OF91-2.ps directory of PostScript files to create technical manual of graphics subsystem on a 300bpi, black-on-white engine. VER.4-CHANGES text material describing updates and changes in release 4 of MAPGEN/PLOTGEN. GCTP-II.tar.Z referential copy of NOAA distribution diskette of General Cartographic Transfomation Package by Atef Alessal. It contains FORTRAN source code and SPCS constants. No main driver program. NMD.gctp2.for.Z sources for USGS-NMD's version of GCTP2. Subroutines in one file. FORTRAN. No driver program. No docs. xspline.tar.Z alternative to UNIX's spline package. Has some added features and methods. Usefull in conjunction with PLOTGEN lines input.
