[Proj] ITRF96/UTM 36N conversion

[Jose Gonçalves]

In order to convert UTM-36N to long-lat with output in decimal degrees you
can use the following PROJ command line:
proj -I -f "%.9f" +ellps=WGS84 +proj=utm +zone=36

You must reformat your file so that each line starts with Easting
(E) and Northing (N), in this order (your file has ID N E ...) and then the
rest of the data.

To calculate distance you can use program GEOD (manpage
http://proj.maptools.org/man_geod.html), which receives coordinates in
lat-long.
Depending on the accuracy you need, it may be acceptable to calculate the
euclidean distance in UTM.
