of equal size. Each pixel is assigned a value. Some raster file formats
are JPEG, JPG, TIFF etc. GeoTIFFs, commonly used in GIS,

Vectors are another format of spatial files for GIS. They are composed of
points, lines and polygons which are generated by a set of commands or
mathematical statements. The Shapefile format is a popular geospatial vector data format.
To represent discrete features like a river, road, building etc,
vectors are preferred.
