Patent ID: 7092957

Claim:
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.
