Abstract
A geospatial modeling system may include a geospatial model database for storing images of a geographical area and a reference digital surface model (DSM) of the geographical area. The images each have associated with them respective first geolocation data with a first accuracy. The reference DSM may include second geolocation data with a second accuracy being greater than the first accuracy. The geospatial modeling system may further include a processor cooperating with the geospatial model database for generating an initial DSM based upon overlapping portions of the images, and aligning the initial DSM based upon the reference DSM to generate a georeferenced DSM having a third accuracy greater than the first accuracy.
