There is no benefit by keeping survey information in the closet and not allowing access from the public to the data. Historically, cartography was a drafting exercise. The lines represented on the map were on a piece of paper, now it is in a digital format in which the lines are in a database where the ends of those lines are represented by coordinates. Delete the term rubber-sheeting immediately. These maps are never finished and require constant updating to keep pace with cadastral transactions.
Parcels are complex features.
To determine the overall geometric relationships tied to physical geography, historical and legal objects, must be considered. Even the definition of what constitutes a parcel often varies widely. It is important, however to stress the importance and use of the parcel in the GIS environment. Though reliability, consistency, accuracy and precision are all-important attributes of a parcel map, they should still be considered only in model of the physical and legal world and not an exact replica. In other words, GIS is simply a model, not an exact replica.
