MnDOT Office of Transportation System Management (OTSM) desires to reduce the cycle time for collecting road data updates from county sources and, opportunistically, capture additional data about road and ancillary uses, e.g. bicycle access. Specifically, this project researched free or low-cost aerial or spatial data from government and other sources to determine if the imagery and spatial data would provide a source of sufficient resolution, accuracy and low cost to maintain MnDOTs various mapping needs.
