Whats the difference between raster and vector maps?
Frequently asked questions:A raster map is a picture. Just like you have a picture on the wall, you have a picture on the screen. Each one of the pixel elements, or pixels, on the screen is just a representation of a picture. With a raster image you do not have any access to the objects in the picture, so if you have a picture of a coastline with bathymetry and buoy markers and shipping lanes, there is no way for you to select the shipping lanes, buoy markers or get a different type of coast line for that picture.
