#88 duplicate Geotiff terrain data Olly Betts Erin Lynch
Description

GeoTIFF is a standard format for terrain data. There are numerous tools for manipulating GeoTIFFs and converting from other formats into GeoTIFF. Currently survex supports hgt and bil for terrain data, but I've been unable to find a free tool to convert from GeoTIFF to either of these formats. It would be great if survex terrain data support were expanded to included GeoTIFF.

#90 fixed Malformed KML on survey, names and passages export Olly Betts Erin Lynch
Description

If I exporting the attached file to KML with the Underground Survey, Station Names, and Passage Walls options all selected, it produces malformed KML. (This does not happen if you use a different combination of export options).

I've attached the data (test.svx), the output KML (test.kml), and the result of opening the KML in Google Earth and then saving the result as a KML (test-export.kml). When open in Google Earth, test.kml has some lines which appear in middle of the ocean, etc. The final element in test-export.kml contains:
