Map analysis may reveal new information in spatial data, and the map could be mental map, geometric-map, summary map and so on. The mental map displays the map in human mind of the distribution of objects in the real world map in Euclidean space, by a transform between the two spaces. Geometric analysis infers the properties of studied object by geometric measurement, operation and graphic statistic, e. g. buffer, overlay, proximity, mass center, shapes, as well as comparison of spatial patterns. Summary mapping tries to filter out and summarize the baseline features of spatial objects based on qualitative induction and intelligent approaches, and based on observations and understanding and physical underling mechanisms of amount of existing maps and patterns.
