ITP: proj - conversion utilities for geographic projections
http://www.vectaport.com/ivmaps/projinfo.html
http://kai.er.usgs.gov/ftp/mapgenproj.html
Program proj is a standard UNIX filter function which converts
geographic longitude and latitude coordinates into cartesian
coordinates, by means of a wide variety of cartographic
projection functions. For many of the projection functions the
inverse conversion, can also be performed.
This package has been an ITP by Kirk Hilliard (kirk@ghoti.com)
for 594 days, and I have sent him two emails since August
without reply.
The work is unlicensed in the sense that it's a work of the US
government so they are not allowed to claim copyright (or
something like that).
I have not yet packaged it (what? Really!) but hope to do so in
the next few weeks.
I will create two packages:
proj-doc: 3 PostScript files documenting the lot.
(Upstream docs are in PostScript, no HTML is possible)
proj: - proj binary
the main conversion filter to convert between
lat,lon to over 100 different projections (or do
the reverse conversion)
- nad2nad and nad2bin binaries
nad2nad is a filter to convert data between North
America Datum 1927 (NAD27) and North American
Datum 1983. nad2nad can optionally process both
State Plane Coordinate System (SPCS) and Universal
Transverse Mercator (UTM) grid data as well as
geographic data for both input and output.
As far as I understand, nad2bin is the x86-endian
version of nad2nad. I need to clear this up.
- libproj.a static library for inclusion of
projection conversion filter in other programs.
(I'll switch to a dynamic library if users request,
and after I have figured out all the details of
doing that.)
