Update 2016
New tool to analyzing height, slope and aspect of a terrain.
Import georaster refactoring :
- Add support for float32 and negatives values
- Add abitity to read geotiff tags (worldfile no longer necessary for tiff raster)
- A new option to fill nodata values
- Possibility to import directly a DEM (i.e without the requirement of a reference plane)
- More user friendly
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.
Import geotiff or common image format georeferenced with a world file.
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.
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.
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.
This part of Blender GIS is designed to assist in the analysis of the topography : height, slope and azimuth (aspect).
There are 2 tools, one to build materials nodes setup for Cycles engine, and a second to configure the color ramp as usual in common GIS software (reclassify values and apply color ramp presets).
