ABSTRACT:
A system and method for describing local area geo-reference features and landmarks in providing high resolution asset location information. Geo-image data is integrated to a mapping application and geo-reference data to add more detailed scale levels to the map. The geo-image data includes geo-images and its features to provide more detailed references to the asset and support the larger references of the geo-reference data. To describe a geo-reference landmark, an original landmark representation is selected with a center point and a radius. The asset location points located at the original landmark representation are compiled along with the asset location points generated by events occurring at the landmark to create a point set. The point set replaces the original landmark representation when a prescribed number of points is reached. The asset location points that are within a specified distance from any of the points in the point set are added to the point set to complete the landmark representation. The geo-image data and landmark representation data are combined to provide high resolution asset location information.
