Description
The Open Terrain dialogue does not specify supported terrain file formats. I was also unable to find this information in the manual.
By trial and error I figured out that hgt is supported. Is that currently the only supported file format?

As noted in #88 (which I'll close as a duplicate of this), you can use GDAL command line tools to convert geotiff to .hgt:
gdal_translate -of srtmhgt N47E013.tiff N47E013.hgt
We're now using GDAL to allow overlaying geodata (GPX, KML, shape files, etc) in aven, so that's one step towards being able to use it to load terrain data.
Note: See
TracTickets for help on using
tickets.
The formats currently supported are documented here for now:
https://trac.survex.com/wiki/TerrainData#Formats
It's not currently in the manual so we can easily update it between releases, though it isn't evolving as rapidly as it was.
We'll probably use GDAL (http://www.gdal.org/) to do the reading eventually, which should then mean we support almost any format.
