Ormeling provides a succinct illustration in a pair of topographic maps, both of the same area of
the South Tirol,
but one made under the Austrian administration prior to 1919 and the other under the
subsequent Italian administration.
Two years ago, I was a participant in a geographic data planning exercise in the State of Victoria.
One of the GIS applications identified in that study was a simple cadastral map of suburban land
parcels, to be created by digitizing a paper map, construction of a database, and then plotting.
It was proposed that the plotted map show the identification of each parcel, along with its area.
Area could be calculated from the database using the routine GIS function, so there would be no
need to input it as a parcel attribute.
