Blender GIS is a Blender addon that bridges Blender and geographic data by importing GIS formats and fetching live geodata for 3D mapping and terrain modeling.
The addon solves the problem of working with real-world geographic information inside Blender's 3D environment. It imports common GIS data formats including shapefiles, raster images, GeoTIFF DEMs, and OpenStreetMap XML. Beyond static imports, it can fetch live web data directly into the 3D view, including OpenStreetMap features like buildings and roads, and elevation data from NASA's SRTM mission. The tool handles georeferencing to maintain spatial accuracy, constructs terrain meshes through Delaunay triangulation, and supports workflows like draping raster textures over triangulated contour lines to create detailed topographic models.
This addon suits designers, architects, and GIS professionals who need to visualize geographic data in a full 3D environment with Blender's modeling and rendering capabilities. It works well for projects requiring terrain visualization, urban planning mockups, or integration of real-world geographic context into 3D scenes. The tool is particularly valuable when you need to combine multiple data sources—vector boundaries, elevation models, and satellite imagery—into a single georeferenced scene.
Development activity shows consistent maintenance with regular updates addressing user needs. The project maintains active documentation including a wiki, FAQ, and quick-start guide to help users navigate its capabilities. The codebase receives ongoing refinement to support current Blender versions and adapt to changes in external services, such as the addition of API key requirements for the OpenTopography elevation service. Community engagement appears steady through the project's documentation resources and issue tracking.
