Terrain Analyst tools allow you to easily find locations or get the height, a profile along a line, or viewshed of the terrain using only your web browser. Also it can clearly be seen that DTM A is based on an interpolation and thus looks smoother than the reality. Both have the same spatial extent but different resolutions. Intermap's online GIS tools are designed to help GIS professionals and non-GIS users perform simple analyses from any web browser and make better terrain-based decisions without the need for any GIS software. DTMs: digital terrain models are either synonymous with DEMs or comprised of a network of vector points instead of a continuous raster Further details here and here Is the file format you have not listed here Contact us and/or consult lists of all raster and DEM file formats supported by ArcGIS, Global Mapper, and QGIS. Digital terrain model (DTM) derived from the 20 m contour lines (A) and the unmanned aerial vehicle imagery (B). Support for this service is built-in into Global Mapper desktop software. The tool GridSurfaceCreate implemented in Fusion Lidar ToolKit (LTK) (McGaughey, 2012) is used to generate a regular mesh of data representing the terrain in raster. The model uses the last echoes of the laser pulse and generates a bare floor surface. Elevation ServiceĮlevation Service offers you an easy way to determine terrain elevation at a given location. Once the classified LAS files are available, the Digital Elevation Model (MDE) is generated.

Intermap subscriptions also provide access to native Web services which enable you to easily leverage 3D spatial information. The starting point for terrains is to use the New Terrain wizard. KMZ, SHP to reduce the number of files for download. Add to this a host of setting out, cogo and modelling functions, DTM Map should be at the heart of any engineering surveyors armoury. Buy and download Digital Terrain Model (DTM) and Digital Surface Model (DSM) data for you custom.
Dtm file format digital terrain model professional#
Taking data from a wide variety of survey instruments, processing raw observations, through to producing professional contour plans couldnt be easier.
Dtm file format digital terrain model software#
Offers grid coverage or raster data that can be used as input data for 3D analysis and modeling. DTM Map is at the core of NRGs software suite. Provides a map image that can be displayed in a browser application or OGC-compliant software.
