Blender addons to make the bridge between Blender and geographic data

Blender GIS

Wiki available for further information.

ESRI Shapefile import / export

A Shapefile is a popular geospatial vector data format for geographic information system software.

This tool can import into Blender most of shapefile feature type. It can also uses attributes data to define Z elevation values or Z extrusion values.

Exporter script can export a mesh to pointZ, polylineZ or polygonZ shapefile.

Note that Blender cannot handle attribute data include in dbase file linked to the shapefile. So if you want import a shapefile for edit it into Blender and then re-export it, you will lose attribute data.

Georeferenced raster importer

Import common image format associated with a world file that describes the location, scale and rotation of the raster in a geographic coordinate system.

You can import the raster as a plane mesh, as backgound image for orthographic view, as UV texture mapping on a mesh or as DEM for warp a mesh with the displace modifier.

Georeferenced render output

This is a tool to create a new camera correctly setup for produce a map render. Georeferencing data (worldfile) are writing in text file accessible from the Blender text editor.

Delaunay triangulation & Voronoi diagram

This script computes Delaunay triangulation in 2.5D. This triangulation is suitable for create a 3D terrain mesh from points cloud or contour lines

The script can also compute Voronoi tessellation in 2D which is the dual of delaunay triangulation. Voronoi diagram is suitable to make neighborhood analysis map.
