This may include performing certain functions such as adding or removing certain items or features, or delineating an area of interest. A static map is simply viewed as is with no user manipulation.

Digitizing mode is used to add your own data layers and attribute information to the map. A shapefile is a type of file created by ArcView IMS software to display and store information for points, lines and polygons.
