Mapping Hacks

Some explorations of the Straits of Gibraltar at a recent “tactical media”
workshop in Ljubljana yielded some insights into using GRASS to marshal geodata
for 3-D terrain modelling. The first image is a false color composite of
Tangier, Morocco, and the second is a true color composite. The third is a
rendered 3-D animation (about 600k) of the Straits […]

Via a post to the GDAL
mailing list, word comes to us that one Chris Soriano has figured out how
to use GDAL and Python to convert digital
elevation models (DEMs) into 3-D mesh data for use with Blender, an Open Source 3-D modelling
package. Although the book contains some POV-Ray
examples, my curiosity about Blender is now thoroughly piqued…

Our good friend Abhijit Menon-Sen has
compiled a pretty thorough guide to compositing your own LandSat-7
scenes from the raw spectral layers available from the Global Land Cover Facility. We used similar
techniques to make the composites used in our fly-over of Bilbao and as a
backdrop to the London Free
Map demo.
As an aside, if you don’t want to […]
