Continuing this thread because there is still a coordinate conversion bug in Therion 5.4.4<br class="">
in coordinate conversion when exporting to KML<br class="">
<br class="">
I have entered the coordinates in UTM based on a point both from an<br class="">
actual GPS and from Google Earth (they are the same) in cs epsg:2154<br class="">
(Lambert 93) or epsg:32631 (WGS84 / UTM 31N)<br class="">
<br class="">
When I look at the output in UTM again, the entrance has shifted<br class="">
directly south for 9 meters.<br class="">
<br class="">
I'm assuming Therion changes the coordinate to something else (more<br class="">
assumptions... WGS84?) and then changes it back again to the desired<br class="">
output format. This conversion produces the wrong results I think.<br class="">
<br class="">
As a workaround, maybe I could enter and export in WGS84 lat/long,<br class="">
however, when I enter </div>
<div class=""> </div>
<div class=""> cs epsg:4326 # WGS84<br class="">
fix E6 43.811399 3.585060 194 10 10 10</div>
<div class=""> </div>
<div class="">I get</div>

<div class="">"can't determine meridian convergence for lat-long systems"</div>
<div class=""> </div>
<div class="">I can't find the format required for WGS84 lat/long in the manual, can someone<br class="">
provide this?<br class="">

Thanks,<br class="">

<div class="">No, we don't modify existing releases. The fix will be included in 5.4.3 eventually, but until then you can use the latest snapshot (<a href="https://therion.speleo.sk/downloads/therion-setup-dev.exe" target="_blank" class="">https://therion.speleo.sk/downloads/therion-setup-dev.exe</a>). </div>

<div class=""><p class="MsoNormal"><font face="Times New Roman" size="3" class=""><span style="font-size: 12.0pt;" class="">the problem is that EPSG:31467 projection uses the "potsdam" datum and the PROJ library used by Therion changed the way how to transform potsdam datum to the standard WGS84 datum – it switched from a simple string parameter (towgs84) to using external grid file (see <a href="https://proj4.org/resource_files.html#transformation-grids" target="_blank" class="">https://proj4.org/resource_files.html#transformation-grids</a> for examples). </span></font></p>
