GRASS can be downloaded for free. A common use of raster data in a GIS is as a background display for other feature layers. For example, orthophotographs displayed underneath other layers provide the map user with confidence that map layers are spatially aligned and represent real objects, as well as additional information. PCRaster is not developed to be a full-blown raster GIS. It lacks functionality for digitising, plotting and other typical GIS tasks.

Raster data is commonly used in GIS as a background display for other feature layers.

Terminology and naming In GRASS GIS terminology, continuous 3D data represented by regular grid or lattice is called 3D raster map. 3D raster map works in 3D in the same was as (2D) raster map in 2D, so it is called the same except for the additional 3D.Some literature or other software may use terms such as 3D grid, 3D lattice, 3D matrix, 3D array, volume, voxel, voxel model, or voxel cube. 2020-06-30 We think it’s adding an online GIS solution to your current desktop set-up or moving entirely to cloud-based software.

While the structure of raster data is simple, it is exceptionally useful for a wide range of applications. Within a GIS, the uses of raster data fall under four main categories: Rasters as basemaps. A common use of raster data in a GIS is as a background display for other feature layers.

Het meten van infrarood licht kan bijvoorbeeld nuttig zijn voor het identificeren van waterbereiken. Omdat het hebben van afbeelding de meerdere banden met licht bevatten zo nuttig is in GIS, worden rastergegevens vaak verschaft als multi-band afbeeldingen.

Raster data comes in as many formats as other image data. Sometimes a number of rasters are packaged together in a “stack.” Taking apart a raster stack or opening some proprietary formats can require special techniques or outside software.
