SRTM Terrain Importer — Blender Extensions This addon imports SRTM (Shuttle Radar Topography Mission) HGT files and creates accurate 3D terrain meshes with proper real-world scaling and elevation-based materials
Elk | Food4Rhino It currently accepts IMG files at a resolution of 1 3 arc second, GeoTIFF files at a resolution of 1 or 3 arc seconds, and HGT files at a resolution of 1 or 3 arc seconds The higher resolution IMG files are available for the United States only and can be downloaded from the USGS National Map Viewer
hgt file DEM — Blog — open. gis. lab Data downloads are distributed as a zipped file in * hgt format The filename of the * hgt file is labeled with the coordinate of the southwest (bottom left corner) cell For example, the file N45W122 hgt contains data from 45°N to 46°N and from 122°E to 123°E inclusive
VTBuilder - vterrain. org Exploits all of the above to do automated placement of vegetation and export to VF files You can import several image formats for viewing in conjunction with other layers, and process them into Tilesets for efficient Enviro visualization of large imagery (up to hundreds of GB)
Heron - Grasshopper Imports IMG and (STRM) HGT files using GDAL Libraries Output is in the form of a mesh Set EarthAnchorPoint Runs a macro to set the Earth Anchor Point in Rhino This is important to minimize distortion translating from the curved surface of the Earth to Euclidean coordinates
TUTORIAL - BlenderGIS - How to drape ortho-photos onto a DEM DSM This plugin is useful for track building because it enables scene geo-referencing using WGS84 or other co-ordinate reference systems (CRS), importing OpenStreetMap data, and importing geo-referenced rasters containing ortho-photography, or digital elevation terrain and surface models
