Hi John,<div><br></div><div>sorry for the late answer. We use following proj4 EPSG:3908 definition in therion:</div><div><br></div><div><div># MGI 1901 / Balkans zone 6</div><div>&lt;3908&gt; +proj=tmerc +lat_0=0 +lon_0=18 +k=0.9999 +x_0=6500000 +y_0=0 +ellps=bessel +units=m +no_defs  &lt;&gt;</div>

<div><br></div><div>It is extracted from proj4 library. If this is not correct (it looks, some coeficients are missing), you may define your own CS in therion.ini,  if you will be able to construct correct proj4 projection definition.</div>

<div><br></div><div>Unfortunatelly, there is no entrance export to KML, but I believe, it will be added soon.</div><div><br></div><div>Best regards, S.</div><br><div class="gmail_quote">On 9 September 2012 11:23, John Stevens <span dir="ltr">&lt;<a href="mailto:john@k-stevens.co.uk" target="_blank">john@k-stevens.co.uk</a>&gt;</span> wrote:<br>

<div>I have been trying to create a model of an area on Montenegro. This area 
uses a local map system VGI which I thought was EPSG:3908</div>
<div> </div>
<div>origin 18 degrees E</div>
<div>scale 0.9999</div>
<div>false easting +6500000</div>
<div>false northing 0.0</div>
<div> </div>
<div>Dx +653</div>
<div>Dy –212</div>
<div>Dz +431</div>
<div>Da +740</div>
<div>Df –0.00010441</div>
<div> </div>
<div>When I use these in a gps (user grid etc) they produce the correct VGI 
coordinate to match the maps.</div>
<div> </div>
<div>I successfully produce a kml file but all the caves are about 400 east of 
where they should be. </div>
<div> </div>
<div>Is EPSG:3908 useable in Therion? </div>
<div> </div>
<div>A second little point, that I may have seen somewhere and now lost.</div>
<div>How do you mark an entrance to show up as a point on a kml file</div>
<div>I have used this for the lox output</div>
