The W. E. Upjohn Center for the Study of Geographical Change:

  • Provides support for GIScience applications in research and administrative decision-making.
  • Converts large-format materials such as maps, charts, oversize books and drawings to georeferenced digital data using Lumiere scanners with unparalleled geometric accuracy.
  • Conducts research in the development of high definition maps.
  • Educates the future workforce in GIS and spatial analysis.

For our work in pairing aerial imagery with legacy topographic maps for the entire US, we received the prestigious Best Digital Map Product – Gold Award and the Overall Americas All-Category Winner of Best Map Product awards in 2013 from the International Map Industry Association. These products are now available as copyrighted Authoritative US Topo maps and the GeoChange Aerial-Topo Map Collection on AvenzaMaps.
