Abstract:
1. A method for geospatially mapping at least one parcel polygon within a geographical region and for displaying at least one specific attribute of each parcel polygon as an attached attribute of latitude and longitude coordinates comprising the steps of: a) digitally scanning paper records of surveyed parcel polygon data of at least the geographical region and the latitude and longitude coordinates of that region and storing the data as a parcel polygon database into a computer memory; (b) obtaining and storing as a digital map database into a computer memory a digital map of at least the geographical region and the latitude and longitude coordinates of that geographical region; (c) displaying images of the parcel polygon lines of the parcel polygon database of step (a) and the digital map database of step (b); (d) overlaying an image of a digital map from the digital map database corresponding to the parcel polygon lines of at least one parcel polygon from the parcel polygon database onto the image of the at least one parcel polygon to form a parcel polygon map using as a reference the latitude and longitude coordinates for that geographical region; (e) determining the geometric centroid of the at least one parcel polygon on said parcel polygon map that has an assigned unique tax identification number and establishing the latitude and longitude for the derived centroid point feature; (f) removing the parcel polygon lines from said parcel polygon map and digitally attaching a single latitude and longitude point feature to the at least one parcel polygon; (g) overlaying a digitized geo-referenced orthophotograph of that geographical region containing latitude and longitude markers onto the resulting parcel polygon map of step (f) to verify the accuracy the accuracy of said parcel polygon map and that a structure having a physical address exits on the at least one parcel polygon; (h) storing at the physical address of the structure as at least one of the attributes for the at least one parcel polygon in a text list in a computer memory; (i) correlating the unique tax identification number for each derived centroid point feature of the at least one parcel polygon with the physical address of the structure as the at least one attribute of that point feature from the text list of step (h); (j) digitally correcting the derived centroid point feature having at least the physical address attribute so that the centroid point is within the periphery of the structure; and (k) displaying the resulting parcel polygon map with the physical address as the at least one attribute for the at least one parcel polygon.
