Geographers are not members of unions. Major professional organizations for geographers include the American Geographical Society, American Society for Photogrammetry and Remote Sensing (ASPRS), Association of American Geographers, Cartography and Geographic Information Society, National Council for Geographic Education, and the Society of Women Geographers, which offer networking opportunities and continuing education. The GIS Certification Institute and ASPRS provide certification to geographers who use GIS technology. The University Consortium for Geographic Information Science is a membership organization of more than 60 colleges and universities that offer GIS education.
