Spatial analysis is one of the more interesting and remarkable aspects of GIS. Using spatial analysis, you can combine information from many independent sources and derive a new set of information (results)—by applying a large, rich, and sophisticated set of spatial operators. GIS professionals use geoprocessing to program their own ideas in order to derive these analytical results. In turn, these results are applied to a wide variety of problems. For example, here, geoprocessing is used to identify suitable sites for parks. The result is a dataset of potential park sites for further evaluation. Site selection logic is used to find areas that are close to where people live but are not too close to existing parks.
