Maps can be a valuable addition to the Web analytics toolbox for Extension programs that use the Web to disseminate information. Extension professionals use Web analytics tools to evaluate program impacts. Maps add a unique perspective through visualization and analysis of geographic patterns and their relationships to other variables. Maps can help assess whether program goals are being met and lead to better understanding of the roadblocks to effective online information delivery. This article shows how maps can be generated using free Geographic Information System software, using the website of the Wisconsin State Cartographer's Office as a case study.
