They both are the two types of spatial data in GIS. Whereas, the raster data represents a grid matrix. The vector data represents data using sequential points or vertices as points, lines and polygons. Hence, there are some primary difference between Vector and Raster data. Example- Temperature, air pressure, elevation, flow and distance etc.įigure 1 Vector and Raster data representation Conclusion However, the distinction between vector and raster data types is not unique. Example- Administrative borders, roadways, rivers, location of a house, forest area, fallow land etc.Ĥ. In GIS, vector and raster are two different ways of representing spatial data. It consists of cells organised in rows and columns with each cell having one value.Ĥ. It is used to store data having discrete boundaries in Point, Line and Polygonġ. (see figure 1) Difference Between Vector Data and Raster Data Vector Dataġ. Hence, a number of raster layers are required for the representation of multiple features over a common plane. Pixels represent each and every geographic element. Raster data is synonyms with grid data as it consists of pixels with an array of cells. Examples- Forest area, Agricultural land, snow cover etc. Polygon feature is mostly distinguished using thematic symbols or colours for visual representation. It takes a minimum of three pairs of coordinates, i.e., X1Y1, X2Y2, X3Y3 to represent an area or polygon.
