A system and method for automatically georeferencing digitized images selects and analyzes image landmark points from disparate sources for image co-registration. A composite alignment of raster images and geographic target vectors is automatically generated using metadata sources for use in geographic display and editing environments. Cartographic alignment of raster images to geographic vector data sets is performed to co-position image data with geographic vector data sets. The co-registration and display permits a meaningful overlay of the data sets and an improved comparison of vector data to the correctly-registered images based on the physical relationships between the vector data and the underlying image features. By incorporating metadata regarding landmarks and other points of interest, users may query target vectors to display attributes of the associated landmarks and create a highly accurate parcel map for validating image information in areas where the data was acquired in sub-optimal conditions.
