A proactive approach is taken every year to update GIS Consortium members on how current their spatial data is. The GIS Consortium photogrammetric vendor is a nationwide engineering, mapping and survey firm that provides high-accuracy geospatial data that the counties cannot. All available orthophoto (aerial imagery similar to what one might see on Google), planimetric (roads, buildings, rivers) and topographic (elevation) data is visualized by the year it was purchased. Aerial LiDAR coverage is also shown with the topography data. This technology produces surface models from laser pulses emitted from a helicopter or plane. The color-coded maps allow communities to budget for updated data by seeing which areas have been updated in the past and if those areas have seen any significant construction or demolition over the years.
Collecting and maintaining accurate data for a Geographic Information System (GIS) program assures the base map is complete and allows GIS users, municipal employees, and decision makers to consume precise data and make decisions based on accurate, complete data. Commercial mapping companiess might provide good data from a regional perspective, but their price and low precision are not ideal for local governments. Up-to-date photogrammetric and topographic data is beneficial to both MGP, Inc. employees as well as their clients.
