Vektor möter Raster - en pilotstudie med GIS om

If playback doesn't Because raster data represent square areas, they describe interiors rather than boundaries as is the case with vector data. Vector data are excellent for capturing and storing spatial details, while raster data are well suited for capturing, storing, and analyzing data such as elevation, temperature, soil pH, etc. that vary continuously from location to location. To reproduce the building in a GIS the computer reads these values and draws a line linking the coordinate positions.

Vector and raster data both have their advantages and A vector GIS works by storing three types of geography Points (a power pole), lines (a power line) and polygons (a power utility service area) in a geographical database, and their attributes are stored in a separate database. Raster GISs (grid cell) work by storing attribute data as grid cell values. There are two essential methods used to store information in a Geographic Information System – GIS for both reflections: Raster and Vector Data Model.
