Municipal Geospatial Partnerships
Geospatial data such as topographic mapping, aerial imagery, and planimetrics create the digital foundation for any engineering project. If you manage floodplains and storm water your first priority should be obtaining accurate up to date topographic data. Flooding is not the only application that benefits greatly from geospatial data. The potential applications for quality geospatial …
