A geographical information system and a method are disclosed for geospatially mapping at 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.
