Topographic maps show information about the shape of the land: both natural features and purpose-built structures. They can be used to obtain precise measurements (within map scale limits) of distance, direction, area and quantity. Depending on the map scale some features are symbolised to provide additional information.
Types of topographic maps
These types of topographic maps are available:
- image maps which use aerial photography corrected to scale as a base, selectively enhanced with topographic information
- line maps which are traditional topographic maps where all features have been interpreted for the map user from aerial photography
- orthophoto maps which are similar to image maps but depict relief, selected enhanced roads and railways on an ortho-rectified image base
- double-sided maps which have image maps on one side and the line map on the reverse.
