GIS provides the framework needed to identify the optimal site(s) for facilities or activities such as store locations, warehouses, service centers, drilling sites, municipal facilities, wireless communications towers, recreational facilities, habitat protection zones, and so on. You provide the criteria, we provide the results.

Location & Allocation: Site Selection

Site selection is the process of finding the location(s) that meet your criteria — conditions that must exist and/or conditions that must be avoided. Conditions can include geographic relationships, such as the inclusion of buffer zones around features, travel-time restrictions, and the like.

In this example, potential locations (white) for a town public water supply well are identified by a process of elimation. Colored regions indicate areas that do not meet the criteria: outside town boundaries (green); unsuitable bedrock lithology (brown); insufficient aquifier flow rates (sand); unsuitable land use (magenta); within 100 meters of roads (grey); within 500 meters of existing water supplies (blue); and within 1000 meters of underground storage tanks (red). What remains are locations that meet the criteria, and they can be further examined for cost, logistics, or other factors to determine the final site.
