National Land Cover Data Template

3D Nature has been working for some time on a useful product to bring the benefits of the USGS NLCD (National Land Cover Database) to VNS users.
The VNS NLCD Content CD is actually a 2-CD set with one VNS Template project, supporting texture image files, and compressed GeoTIFF raster images for the 'lower 48' US states.
The Template project and supporting images will be installed on your computer, The (large) GeoTIFF images will not. To use the Template, VNS users simply create a new project, specifying the NLCD Template project as an active template to inherit from. This will provide 22 pre-made ecosystems in the project from the very start. These 22 ecosystems correspond to the 22 basic landcover types defined by NLCD.
Next, DEM data is added, the GeoTIFF imagery is copied from the CD, cropped if necessary and loaded as a ColorMap. The result is a fully populated, vegetated/urban landscape driven by the landcover classification in the NLCD data.
