Hi Bill,

I do not really understand why to export survey stations as a geotiff file (raster, image). Survey stations are points (vectors) and are more easier to manage through GIS softwares as shapefiles (vector format). This is the Therion ESRI output.

In the ESRI output folder, you have several shapefiles in 2D (exported as map) and in 3D (exported as model): outline, areas, lines, areas, points, shots3d, stations3d (several files for each shapefile).

Stations3d contains all the stations of the survey…

The points shapefile should also contain the points station. See the attribut table associated to this file and use that to select the points you want to plot.

For one of my main project, I wanted to produce a clean georeferenced map with :

the survey with a rendering depending on the zoom used,
at important zoom, the stations with their altitude,
and overlays as OSM, Geology, hillshade, altitude contours,…

We used that in a QGIS project that we coupled with the Merging Maps app. This is still in development, but that permits to do field prospection with all the cave database and GPS positioning on your phone.
