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. Subscribers may customize the NPDP to perform a variety of spatial analysis/reporting functions. Under public/private alliances, agreements are negotiated with individual property assessor'"'"'s offices whereby they receive a portion of NPDP service provider revenue in return for parcel map database updates. Such on-going commerce between data sponsors and the NPDP service provider is utilized to assure a sustained and expanding flow of increasingly competent content.

Claims

1. A method for retrieving and displaying geographic parcel boundary polygon maps comprising:

receiving, by a server, a request for a parcel boundary polygon map for a selected parcel;

searching, by the server, a multi-jurisdictional digital parcel map database for the selected parcel boundary polygon and the boundary polygons of adjacent and surrounding parcels, the database having information about individual land parcels normalized to a common spatial data protocol, including polygon data used to describe the boundaries of a plurality of properties, wherein the multi-jurisdictional digital parcel map database includes a plurality of files arranged in separate service area directories corresponding to multi-jurisdictional service areas within two or more states;

transmitting the parcel boundary polygon map data for the selected parcel along with the adjacent and surrounding parcels to a client computer for display, wherein the transmitted parcel boundary polygon map includes the selected parcel polygon along with adjacent and surrounding parcel boundary polygons around the selected parcel.

2. The method of claim 1 wherein the request for a parcel boundary polygon map for a selected parcel includes one or more parcel attributes, including the street address, city name, state, zip code, and APN of the selected parcel.

3. The method of claim 1 wherein the multi jurisdictional digital parcel map database includes parcel attribute data linked to a non geographic database associated with the selected parcel.

4. The method of claim 1 wherein the selected parcel in the transmitted parcel boundary polygon map data is highlighted or otherwise differentiated to define its location.

5. The method of claim 4 wherein the selected parcel boundary polygon is highlighted by changing the color of the parcel boundary polygon of the selected parcel to a different color than the parcel boundary polygons of the adjacent and surrounding parcels.

6. The method of claim 4 wherein the selected parcel boundary polygon is highlighted by increasing the brightness of the parcel boundary polygon of the selected parcel compared to the brightness of the parcel boundary polygons of the adjacent and surrounding parcels.

7. The method of claim 1 wherein the server first searches an index of jurisdictional databases to identify the portion of the multi-jurisdictional database in which the selected parcel is located.

8. The method of claim 7 wherein the server, after identifying the portion of the multi-jurisdictional database in which the selected parcel is located, searches that identified portion for the selected parcel.

9. A method for retrieving and displaying geographic parcel boundary polygon maps comprising:

receiving, by a server, a request for a parcel boundary polygon map for a selected parcel;

searching, by the server, an index of a multi jurisdictional digital parcel map database to identify a portion of the multi-jurisdictional database in which the selected parcel boundary polygon and the parcel boundary polygons of adjacent and surrounding parcels are located, the database containing information about individual land parcels normalized to a common spatial data protocol, including polygon data used to describe the boundaries of a plurality of properties;

searching, by the server, for the selected parcel in the identified portion of the multi-jurisdictional database; and

transmitting the parcel boundary polygon map data for the selected parcel along with the adjacent and surrounding parcels for display, wherein the parcel boundary polygon map includes the selected parcel polygon along with adjacent and surrounding parcel boundary polygons around the selected parcel, with the selected parcel highlighted.

10. The method of claim 9 wherein the index comprises a look-up table associated with the multi-jurisdictional parcel map database.

11. The method of claim 9 wherein searching the index of the multi jurisdictional digital parcel map database to identify a portion of the multi-jurisdictional database in which the selected parcel boundary polygon map and the parcel boundary polygon maps of adjacent and surrounding parcels are located includes locating a jurisdictional identifier for the identified portion of the database.

12. The method of claim 9 wherein the multi-jurisdictional digital parcel map database includes a plurality of files arranged in separate service area directories corresponding to multi-jurisdictional service areas within two or more states.

13. A method for retrieving and displaying geographic parcel boundary polygon maps comprising:

receiving, by a server, a request for a parcel boundary polygon map for a selected parcel;

searching, by the server, a multi-jurisdictional digital parcel map database for the selected parcel boundary polygon and the parcel boundary polygons of adjacent and surrounding parcels, the database having information about individual land parcels normalized to a common spatial data protocol, including polygon data used to describe the boundaries of a plurality of properties;

transmitting the parcel boundary polygon map data for the selected parcel along with the adjacent and surrounding parcels for display, wherein the parcel boundary polygon map includes the selected parcel polygon along with adjacent and surrounding parcel boundary polygons around the selected parcel.

14. The method of claim 13 wherein the request for a parcel boundary polygon map for a selected parcel includes one or more parcel attributes, including the street address, city name, state, zip code, and APN of the selected parcel.

15. The method of claim 13 wherein the multi-jurisdictional digital parcel map database includes parcel attribute data associated with the selected parcel.

16. The method of claim 15 wherein the request for a parcel boundary polygon map for a selected parcel includes a parcel attribute.

17. The method of claim 13 wherein the selected parcel in the transmitted parcel boundary polygon map data is highlighted or otherwise differentiated to define its location.

18. The method of claim 16 further comprising transmitting parcel attribute data associated with the selected parcel.

19. The method of claim 18 further comprising transmitting parcel attribute data associated with the adjacent and surrounding parcels.

20. The method of claim 13 wherein the server first searches an index of the multi jurisdictional digital parcel map database to identify a portion of the multi jurisdictional database in which the selected parcel boundary polygon and the parcel boundary polygons of adjacent and surrounding parcels are located.

21. The method of claim 20 wherein searching the index of the multi jurisdictional digital parcel map database includes locating a jurisdictional identifier for the identified portion of the database.

22. The method of claim 20 wherein the server, after identifying the portion of the multi-jurisdictional database in which the selected parcel boundary polygon and the parcel boundary polygons of adjacent and surrounding parcels are located, searching the identified portion for the selected parcel.

23. The method of claim 20 wherein the index comprises a look-up table associated with the multi jurisdictional parcel map database.

24. The method of claim 13 wherein the multi jurisdictional digital parcel map database includes a plurality of files arranged in separate service area directories corresponding to multi-jurisdictional service areas within two or more states.
