Computerized national online parcel-level map data portal
First Claim
1. A method for selecting a parcel to be viewed along with adjacent and surrounding parcels on the display screen of a computer, wherein the data used to describe the selected parcel, and adjacent and surrounding parcels is obtained from a multi-jurisdictional, digital parcel boundary polygon map database, and wherein said selected parcel and the adjacent and surrounding parcels lie within or cross the extents of a bounding box whose coordinates are selected to cover the viewing extents of the portion of a display screen devoted to a parcel boundary polygon map, the method comprising:
- locating within a multi jurisdictional digital parcel map database the jurisdictional service area in which the selected parcel is located;
locating within the pertinent jurisdictional service area the parcel boundary polygon of the selected parcel;
creating a rectilinear bounding box to define a retrieval area;
identifying whether additional jurisdictional service areas intersect the bounding box;
selecting all parcel boundary polygons within each said jurisdiction within or crossing the bounding box;
retrieving said parcel data from all jurisdictions located within the bounding box; and
,providing said data for display on a computer screen.

Abstract
A National Online Parcel-Level Map Data Portal (NPDP) is provided that optimizes online delivery of parcel-level maps and linked attribute data. To do this, the NPDP manages a database of assembled and current vector based parcel data in a spatial format (GIS) that enables geocoded parcel boundaries to be linked to property tax records. A user enters a street address into an appropriate screen window to call up and view road right-of ways, all parcel boundaries and the “exact” address location as a highlighted parcel area. In addition, a list of property record attributes such as owner, use code, assessed value and year constructed can be displayed. Other on screen parcels can likewise be selected if one wishes to view their linked attributes.

16. A method for retrieving and displaying geographic parcel boundary polygon maps comprising:
-
receiving by a server a request for a parcel boundary polygon map area for a selected parcel based upon a street address; searching by the server a multi-jurisdictional digital parcel map database for the parcel boundary polygon record for the selected parcel boundary polygon having said street address, said boundary of said selected parcel, along with the parcel records of adjacent and surrounding parcels, said parcel records including the geocoded parcel boundary polygon data which defines each of the line segments for each of the adjacent and surrounding parcel boundary polygons; defining a rectilinear parcel boundary retrieval area, wherein four coordinates define said retrieval area; retrieving the geocoded polygon data for each of the parcel boundary polygons that fall within or cross said rectilinear retrieval area, which retrieved data is written to a selection set; and transmitting said selection set of retrieved parcel boundary polygon map data, said data including the parcel boundary polygon data for the selected parcel having said street address along with parcel boundary polygon data for the adjacent and surrounding parcels to a remote appliance having a screen display, wherein the transmitted parcel boundary polygon map data includes the selected parcel boundary polygon along with adjacent and surrounding parcels around the selected parcel the selected parcel boundary polygon highlighted or otherwise differentiated. - View Dependent Claims (17, 18, 19, 20, 21)
