However, we are only used to creating '. Image classification for RF propagation studies must accurately model clutter in terms of its influence on radio wave propagation. A client wants us to provide them with an InRoads digital terrain model (DTM) for a project we are doing. These features are classed according to their physical and electrical properties.Īverage obstacle height, local absorption power loss, co-efficients of correction and distance to clearing are some of the clutter-specific parameters that can be set and adjusted in propagation modeling. ClutterĬlutter refers to a Land Use/Land Cover classification of surface features which impact on radio wave propagation. Geodata types: Digital Terrain Model (DTM)Ī continuous model of ground-level land surface, represented by a digital raster grid with each grid cell holding an elevation value.Ī DTM is a fundamental data input for radio propagation studies in that terrain blocks and reflects radio waves.

By ordering this data through us we are able to ensure that it can be used by our software. DTMs are used especially in civil engineering, hydrology, hydraulics, surveying, geography, and remote sensing. Filters are used to remove surface items. On the example of the Mordovia Republic examined the possibility of using GIS technology, geoinformational and cartographic digital terain models (DTM, digital elevation model, DEM) for land.

Our processing engine generates the DTM by removing the vertical features that are not. TeleResources can provide data sets for any area of the globe ranging from 5m to 90m order of accuracy. Digital Terrain Models (DTM) is a topographic model of the Earth that can be manipulated by computer programs. DSM2DTM converts a raster digital surface model (DSM or elevation) into a bare-Earth digital terrain model (DTM). Site Scan is now producing Digital Terrain Models (DTM) as TIFF files.
