This simulation demonstrates the use of a partial texture defined by linked JPEG2000 image files and a Volume-of-Interest overlay. The simulation includes a color shaded relief view of the whole landscape (stored in the landscape file) and a linked texture made up of six color-infrared digital orthophotoquad images, which covers only a portion of the landscape. The DOQ images were acquired as compressed images in MrSID format and used directly in that form in the Landscape Builder to create a compressed JPEG2000 texture layer for the landscape file. The Volume-of-Interest overlay depicts spherical volumes centered on various arbitrary points on the landscape. The positions of these volumes can be edited in TNTsim3D using the Point Overlay tool. The simulation covers an area of the Guadalupe Mountains in west Texas, USA (about 469 square kilometers). Portions of this remote desert area are included in Guadalupe Mountains National Park. Guadalupe Peak, near the southern edge of the landscape, is the highest point in Texas, rising to an elevation of 2667 meters. The sparse desert vegetation shows as shades of orange to red against a pale-green background of rock and soil in the color-infrared images.
