Using GIS to maintain tax maps

It was recently realized by the Elk Grove Village, IL GIS staff that
most, if not all, of the land division information related to properties
was being provided them by their data sharing agreement with Cook
County. The data represents all of the components a piece of land is
described by in a legal description and includes the Township, Range,
Section, Quarter Section, Subdivision, Block, Parcel, and Lot. All of
this information was combined in The Village’s interactive GIS map so
that staff can have quick access to this information when faced with
future land divisions and/or inquiries without an address to identify
the location.
