Each polygon will receive a label at its centroid which witl be attributed with its proper PIN. Through this PIN, any e�tisting or future database that has PIN-based information can be related to the parcel database. Then that data can be analyzed with other data or maps. If necessary, other attributes will be added at this time. Quality control proof plots are made of the new computerized property maps. These plots are checked by senior mapping technicians ta verify that each parcel, as detailed on the map, matches the source documentation used to construct the finished digital property map. If any additional information is needed on the finished map, it is marked on the proof plots. , After the final map proof plots have been reviewed, any revisions are then entered into the database and the final map sheets are plotted on reproducible material.
