iMap 3.1 has been released. A few comments on other websites mention that people are using this to map genealogy data (migrations, etc.).
iMap 3 is a data visualisation tool designed to map large amounts of latitude/longitude data (or US ZIPcodes). iMap imports data from databases or spreadsheets and maps it onto image or vector maps. Database queries can be used to map only a subset of the data or to filter the data for a certain criterion. iMap is extremely expandable: it offers a plugin format enabling anyone to extend its functionality. Maps can be exported as high quality PDF files for cross-platform viewing. Whether you are outlining marketing strategies, defining sales territories, tracking population trends, or visualizing ecological distributions, iMap offers a flexible and affordable solution.
