PROJ 4.4.6 WIN32 Binary Release =============================== This is a package of pre-built binaries for PROJ 4.4.6 for Win32 systems. After the package is unpacked the PROJ\BIN directory should be added to your path. eg. C:\> set PATH=%PATH%;C:\PROJ\BIN If you unpack the distribution somewhere other than C:\, you will also have to set the PROJ_LIB environment variable so that PROJ can find initialization files. eg. C:\> set PROJ_LIB=C:\Software\PROJ\NAD Once these steps are complete, you should be able to use the various PROJ utilities from the commandline. eg. C:\> proj.exe -I +proj=utm +zone=11 +ellps=WGS84 332000 4000000 (input) 118d52'1.182"W 36d7'48.593"N (output) C:\> See the PROJ.4 web site for more details on PROJ. http://www.remotesensing.org/proj Those wanting to use PROJ.4 DLLs for other applications like MapServer can just copy the PROJ\BIN\PROJ.DLL file, and ignore the .EXE files. However, the PROJ_LIB environment variable will still need to be set to enable use of initialization and datum grid shift files.
