a
tool for viewing and processing many kinds of geospatial data- merges and resamples multiple elevation files
- import elevation grids from DEM, SDTS DEM, MicroDEM, GTOPO30, SRTM, DTED, CDF/netCDF, PNG, TIF, GeoTIFF, PGM, Surfer GRD, TerraGen, raw data, ArcInfo ASCII/Binary, SRTM HGT, and many other formats
- export elevation grids to ArcInfo ASCII Grid, GeoTIFF, TerraGen, BMP, STM, MSI Planet, VRML ElevationGrid, RAW/INF for MSFS, ChunkLOD (.chu), PNG 16-bit, 3TX.
- reads and writes Binary Terrain (BT)
- import TIN data from DXF
- lets you view and define an area for merging and resampling BT format, which can be used by the VTP Terrain Library and Enviro runtime
- supports undersea data, and conversion of data between coordinate systems, such as merging of DEM files across a UTM boundary
- reads road centerline vectors from USGS DLG, ESRI SHP, NTF and other GIS formats
- does cleanup processing on the road network topology
- allows the user to define intersection behavior and road attributes including number of lanes and direction of traffic flow
- writes to RMF which can be used by the vtlib Library and Enviro runtime
- reads and writes VTST files
- select, move and delete buildings
- edit building attributes (shape, number of stories, color, etc.)
- imports land-use and vegetation-coverage data from USGS LULC and ESRI SHP files
- imports species lists and vegetation zones (biotypes) from text/XML files
- exploits all of the above to do automated placement of vegetation and export to VF files
- imports multiple layer types from compound file formats - TIGER (roads, hydrography) and NTF (roads, built structures)
- you can import several image formats for viewing in conjunction with other layers
