Vector Data and Raster Data in GISAli Jaafar
A common use of image data in a GIS is as a background display for other feature layers. For example, orthoimages displayed underneath other GIS layers provide the map user with confidence that map layers are spatially aligned and represent real objects, as well as additional information. Three...
Raster data is comprised of grid cells. Unlike its vector counterpart which is comprised of vertices and paths. These are the two primaryspatial data typesin GIS. Accuracy depends on cell size. Cell size must be small enough to capture the required detail. And as resolution increases, the siz...
The two primary types of spatial data arevector and raster datain a GIS. But what is the difference between raster and vector data? When should we use raster and when should we use vector features? Find out more about the spatial data models commonly used. ...
