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.
Claims20
A geospatial modeling system comprising:
- a geospatial model database configured to store a plurality of images of a geographical area and a reference digital surface model (DSM) of the geographical area, the plurality of images each having associated therewith respective first geolocation data with a first accuracy, the reference DSM including second geolocation data with a second accuracy being greater than the first accuracy;
- and
- a processor cooperating with said geospatial model database and configured to
- generate an initial DSM based upon overlapping portions of the plurality of images, and
- align the initial DSM based upon the reference DSM to generate a georeferenced DSM having a third accuracy greater than the first accuracy.
A geospatial modeling system comprising:
- a geospatial model database configured to store a plurality of images of a geographical area and a reference digital surface model (DSM) of the geographical area, the plurality of images each having associated therewith respective first geolocation data with a first accuracy, the reference DSM including second geolocation data with a second accuracy being greater than the first accuracy;
- and
- a processor cooperating with said geospatial model database and configured to
- generate an initial DSM based upon overlapping portions of the plurality of images,
- align the initial DSM based upon the reference DSM to generate a georeferenced DSM having a third accuracy greater than the first and second accuracies, and
- generate updated respective first geolocation data for each of the plurality of images based upon the georeferenced DSM.
A computer implemented method for geospatial modeling using a plurality of images of a geographical area and a reference digital surface model (DSM) of the geographical area, the plurality of images each having associated therewith respective first geolocation data with a first accuracy, the reference DSM including second geolocation data with a second accuracy being greater than the first accuracy, the method comprising:
- generating an initial DSM based upon overlapping portions of the plurality of images;
- aligning the initial DSM based upon the reference DSM to generate a georeferenced DSM having a third accuracy greater than the first accuracy;
- and
- displaying at least one image based upon the georeferenced DSM.
