Bathymetric maps ( a more general term where navigational safety is not a concern ) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed.
22.
A variety of computer screens give field commanders virtually everything they need to know : three-dimensional terrain models, enemy locations and movements, flight paths and missile trajectories and analyses of possible courses of action.
23.
He said ammunition, mortars, maps and a terrain model were found at the hospital, along with " other things that made it very clear it was being used as a military command post ."
24.
Terrain measurement techniques are vital to quantitatively describe the form of the Earth's surface, and include differential GPS, remotely sensed digital terrain models and laser scanning, to quantify, study, and to generate illustrations and maps.
25.
"' CitySurf Globe "'family models raster data, such as high resolution satellite images and aerial images, under high speeds using digital terrain model and vector geographical information systems and accordingly serves these via internet or local nets.
26.
Free DEMs are also available for Mars : the MEGDR, or Mission Experiment Gridded Data Record, from the Mars Global Surveyor's Mars Orbiter Laser Altimeter ( MOLA ) instrument; and NASA's Mars Digital Terrain Model ( DTM ).
27.
NASA / DLR released imagery and summary information from a survey orbit, two high-altitude orbits ( 60 70 m / pixel ) and a low-altitude mapping orbit ( 20 m / pixel ), including digital terrain models, videos and atlases.
28.
The advent of very high resolution images of the surface from the HiRISE, Context ( CTX ) satellite cameras as well as the Mars Orbital Laser Altimeter ( MOLA ) digital terrain models have drastically improved our understanding of the networks in the last decade.
29.
Key modeling features include B�zier / Coons patches; mechanical and organic forms using the previous as well as metaforms, patches, subdivisions, displacements, or skinning, plus specialty tools such as Terrain models, Platonic solids, geodesic spheres, double line / wall objects, staircases, helixes, screws, and bolts.
30.
Techniques such as adaptive least squares stereo matching are then used to produce a dense array of correspondences which are transformed through a camera model to produce a dense array of x, y, z data which can be used to produce digital terrain model and orthoimage products.
