GIS distinguishes itself from cartography by the ability to analyze data. It is able to transform map data into customized information. (89). Not all spatial analyses can be done through computation and formulas. Visualization remains one of the strongest methods for analyzing data on a map. In tandem, visualization and computation is what gives GIS [...]

Spatial analysis differs from mapping because it generates more information or knowledge than can be obtained from maps or data alone. Mapping represents geographical data in a visual form. It doesn’t create more information than what was originally used, but it allows us to discover patterns within that information. Earliest computer cartography system in 1964 [...]
