The special GIS (Geographic Information System) Browser allows integration and interaction of historical maps with current geospatial data and other historical maps. Examination of the maps in GIS reveals changes in the history of the areas shown on the maps. The current geospatial data that can be overlaid and compared to the historical maps includes roads, lakes, parks, provincial boundaries, digital orthophotos (aerial photography), topographic mapsheets, and satellite imagery. Users can create, save, and print custom maps, as well interactively blend/fade/merge and overlay/swipe multiple map layers for enabling real-time visual change analysis over the Internet. Results of the user customized map layer visualizations can be saved and downloaded as new images, complete with the georeferencing information, thereby allowing easy integration into other desktop GIS applications.
