In order to convert UTM-36N to long-lat with output in decimal degrees you can use the following PROJ command line:<div><br></div><div>proj -I -f "%.9f" +ellps=WGS84 +proj=utm +zone=36</div><div><br></div><div>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.</div>
<div><br></div><div>To calculate distance you can use program GEOD (manpage <a href="http://proj.maptools.org/man_geod.html">http://proj.maptools.org/man_geod.html</a>), which receives coordinates in lat-long.</div><div>Depending on the accuracy you need, it may be acceptable to calculate the euclidean distance in UTM.</div>

Hello,<br>
<br>
I would like to convert coordinates in ITRF96 / UTM-36N format (measured<br>
with DGPS) to latitude and longitude values that I can use with Google Maps.<br>
I tried to do the conversion using proj but I couldn't do it. What command<br>
should I use for this?<br>
<br>
This is what my coordinates file looks like:<br>
<br>
2 4415699.244828 482321.027219 950.950000 5 | 2 | 1.400<br>
3 4415697.320372 482321.307750 951.050000 5 | 2 | 1.400<br>
4 4415696.356924 482321.975236 951.050000 4 | 2 | 1.000<br>
<br>
This is what I want:<br>
<br>
2 39.8911748 32.7932165<br>
3 39.8911574 32.7932198<br>
4 39.8911488 32.7932277<br>
<br>
I also would like to find the distance (in meters) between two points whose<br>
ITRF96 / UTM-36N coordinates are known. I googled it but I didn't find<br>
anything about it. Can you please help me with this?<br>
<br>
Thanks.<br>
