Computerized national online parcel-level map data portal
DC CAFCFirst Claim
1. An interactive computer implemented method for retrieving geographic parcel boundary polygon maps and associated parcel attribute data linked to a non-graphic database, wherein the data is acquired electronically, comprising:
- a. activating a computer terminal connected to a computer network;
b. accessing an applications program for access to the data;
c. accessing a data entry screen and entering a parcel attribute to call up the parcel selected;
d. subsequently accessing a national parcel map database comprising multiple jurisdictional databases which have been normalized to a common data protocol;
e. searching a jurisdiction look up table associated with the national parcel map database, said look up table indexed for identification of the pertinent jurisdictional database, whereby a numerical jurisdictional identifier for the selected jurisdiction is located, and the identified jurisdictional database thereafter accessed; and
,f. thereafter displaying on screen a parcel boundary polygon map, along with surrounding parcel boundary polygons, the default scale of the displayed map selected to fill the computer display screen with parcel boundaries within a selected distance around the subject parcel, the selected parcel boundary polygon highlighted, defining both the location and boundary of the parcel, and the associated attribute data for the highlighted parcel displayed.

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.
