Terrains with Site Models
We have produced a number of terrain models that include georeferenced
site models, or other cultural features. The following links provide examples
of terrains with building models, and weather simulations accurate overlayed.
All of these currently use the Anchor/LOD terrain representation.

McKenna MOUT site
This is a small region of the McKenna MOUT
site in Fort Benning. The imagery is 15 cm resolution imagery, and
this site is not tiled. The elevation mesh is a TIN (triangulated
irregular network). It includes building models with texture maps
that were automatically extracted from the aerial imagery using SRI's
Cartographic Modeling Environment (CME) product.

Fort Benning, GA
A 3x2 km region around Fort Benning,
with 15 cm resolution imagery. This dataset contains a total of 11
levels of detail, with a total dataset size of 166 MB. The imagery
for this dataset is 18932 x 15533 pixels (JPEG compressed, grayscale).
This dataset contains overlayed VRML
site models (buildings, roads, and functional areas). These models
were extracted automatically from SRI's Cartographic Modeling Environment
(CME) product, and directly incorporated into the VRML terrain.

Denver, CO
A 233x206 km region encompassing part
of Colorado state, with 30 m resolution imagery. The city of Denver
is toward the lower right corner of image. This dataset contains a
total of 9 levels of detail, with a total dataset size of 73 MB. Elevations
are exaggerated by a factor of 5. The imagery for this dataset is
6854 x 7755 pixels (JPEG compressed).
This model contains an overlay of a Clear
Air Turblence (CAT) isosurface that was recorded over this portion
of the Rockies. The CAT VRML model was provided by the National
Center for Atmospheric Research (NCAR), Boulder.

Camp Pendleton, CA
A 59x70 km region around the Camp Pendleton
site in Southern California with 30 m resolution imagery. This dataset
contains a total of 8 levels of detail, with a total dataset size
of 6 MB. Elevations are exaggerated by a factor of 5. The imagery
for this dataset is 1992 x 2317 pixels (JPEG compressed).
This models contains an overlay of wind
vectors at 400m resolution that were supplied by the Naval Oceanographic
Office (NAVO).
