What is "spatiomap"

A spatiomap is document similar to a map, but based on an orthophoto. Often, some annotations are added to the orthophoto. Similar to normal maps, can display a north arrow, a scale bar and cartographical information like the used projection. Spatiomaps are useful when other reliable source are missing for a certain area. They are frequently used during disaster relief.

An image map is a similar document, but is mostly regarded as an orthophoto with some points, lines or polygon layers of a traditional map drawn over the orthophoto. An image map resemble a standard general purpose map but adds the use of the orthophoto as a background.
