Increased access to geographic information systems (GIS) technology has expanded the tools available to support Extension programming. However, working with large spatial datasets can still be difficult for less experienced users. GIS software allows the use of custom script programs and toolboxes to expedite and simplify data analysis. This article demonstrates the use of a customized GIS-based spatial statistics tool in an emergency planning and response context. In our example, we use the tool to tabulate population statistics within a user-defined area around several supermarkets made inoperable due to flooding.
