What type of map is defined as lacking relief data?

A planimetric map is characterized by its representation of the horizontal positions of features without incorporating elevation or relief data. This type of map typically shows the distribution of various features such as roads, buildings, and bodies of water in a two-dimensional format, making it an effective tool for understanding spatial relationships and layouts. Since it excludes elevation information, planimetric maps focus solely on the geometry and arrangement of features on a flat plane.

Topographic maps, on the other hand, include both elevation data and relief features, depicting the shape of the terrain. Physical maps incorporate landforms and elevation as well, usually displaying mountains, valleys, and other physical features. Relief maps represent three-dimensional terrain on a two-dimensional surface, emphasizing changes in elevation and landforms.

Overall, the distinctive characteristic of a planimetric map is its lack of relief information, allowing users to analyze spatial relationships without the complexity introduced by elevation changes.
