Chinese City and Irrigation System 1932
Planimetric maps are a subset of topography, showing only the horizontal position of features on the Earth’s surface. What is different from this map from a tradition topographic map is they lack the elevation feature. Also referred to as a line map, Planimetric maps show both natural as well as man-made physical features such as roads, sidewalks, fence lines, piers, and other small construction or terrain features. The map shown above is Planimetric map of China, by the Japanese Expeditionary Forces in Shanghai showing a walled Chinese city and irrigation system from 1932.
