How does MDAL represent TINs internally?<br>
<br>
Where is the QGIS coding style? The link on that page goes to a 404 page.<br>
<br>
I may try to find out what the Carlson TIN header means. I'm talking to <br>
another surveyor tomorrow, who has tried to get the spec, but since I last <br>
talked with him about it, I met some people (not programmers) from Carlson, <br>
generated a TIN from a point cloud as they watched, exported it as Carlson, <br>
and handed it to them on a flash drive.<br>
<br>
