System and method of geospatially mapping topological regions and displaying their attributes
First Claim
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) determining the centroid of each parcel polygon;
(b) establishing a latitude and longitude point feature at the centroid of each parcel polygon;
(c) assigning a unique tax identification number to each of the point features;
(d) correlating the unique tax identification number of the point feature to a text list of at least one attribute of the point feature and thereby attaching said attribute to each point feature; and
(e) displaying a geospatial map of the geographical region and point features with the attached attribute within a GIS or CAD system.

Abstract
A geographical information system and a method are disclosed for geospatially mapping a least one parcel polygon within a geographical region and for displaying at least one specific attribute of each parcel polygon, i.e. a topological area within the given geographical region, as an attached attribute of latitude and longitude coordinates. The centroid or center point of each of the parcel polygons is determined and stored into conventional computer storage means. The latitude and longitude point feature at the centroid of each parcel polygon is established and similarly stored. A unique tax identification number, e.g. the Assessor Parcel Number (APN) or Parcel Identifier Number (PIN), is assigned to each of the point features. A correlation is then made between the unique tax identification number of the point feature to a text list of at least one attribute, e.g., the physical address of the parcel polygon, of each of the point features. This attribute becomes attached to each point feature. The resulting parcel polygon map and point features with one or more of the attached attributes can then be displayed within a GIS or CAD system to provide the user, for example, accurate locations of street addresses for use in environments that require pinpoint accuracy, such as emergency response.

34. A geographic information system 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:
-
(a) means for digitizing and storing surveyed parcel polygon data for the geographical region and for displaying a digital map of said region;
(b) means for overlaying each of the resulting parcel polygons onto said digital map with reference to the latitude and longitude coordinates of said region to form a parcel polygon map;
(c) means for determining the geometric centroid of each parcel polygon having a unique tax identification number on said parcel polygon map from means (b) and for establishing the latitude and longitude point feature for each centroid;
(d) means for removing the parcel polygon lines from the parcel polygon map from means (c) and for displaying a parcel polygon map showing a single latitude and longitude point feature for each parcel polygon; and
(e) means for correlating the unique tax identification number for each point feature with at least one attribute of the point feature from a text list, for attaching said attribute to each point feature, and for displaying said parcel polygon map from means (d) with the attached attribute. - View Dependent Claims (35)

(e) geometric algorithmic means for determining the geometric centroid of the at least one parcel polygon on said parcel polygon map that has an assigned unique tax identification number arid for establishing the latitude and longitude for the derived centroid point feature;
(f) attaching means for removing the parcel polygon lines from said parcel polygon map and for attaching a single latitude and longitude point feature to each parcel polygon;
(g) storage means for a text list of attributes for each parcel polygon according to its assigned unique tax identification number;
(h) correlation means for correlating and attaching the unique tax identification number for each derived centroid point feature of said parcel polygon map to at least one attribute of that point feature from said text list stored in storage means (g);
wherein said at least one output device is capable of displaying the resulting parcel polygon map from correlation means (h) with the attached attribute. - View Dependent Claims (37, 38, 39, 40)
