This looks great! I've been looking at tools to do viewshed analysis. Already being familiar with Blender, this is just the type of project I was looking for.

This looks great! I've been looking at tools to do viewshed analysis. Already being familiar with Blender, this is just the type of project I was looking for. I'm interested in some what's visible through the horizon. I wonder, does the 3d model import take into account the curvature of the earth, or is a projection onto the plane they start with?

The raw data is in lat/long and elevation. You use a tool like QGIS to project the raw data into xyz data [0]. QGIS and the projection model determine the coordinates of the data that get rendered. Blender just renders the xyz data. [0] See for example the FAQ for the blender project https://github.com/domlysz/BlenderGIS/wiki/FAQ https://github.com/domlysz/BlenderGIS/wiki/FAQ
