The Dane County Parcel Database was derived from a variety of source maps including U.S. General Land Office survey plats, deed descriptions, subdivision plats, certified survey maps and right-of-way plats. All new parcels are entered into the database using coordinate geometry (COGO). The map provides a representation of the geometry and topology of tax parcels. The attributes are derived from the Dane County Treasurers database. It is not intended to be used for the legal determination of land ownership or to be in any way a substitute for the land ownership and interest descriptions contained in individual deeds.

Only City Engineering maintained features are shown. There may be other utilities owned by Parks, the UW system and other private entities. This data is NOT to be used to replace any Diggers Hotline calls.

We constructed a time-series spatial dataset of parcel boundaries for the period 1962-2005, in roughly 4-year intervals, by digitizing historical plat maps for Dane County and combining them with the 2005 GIS digital parcel dataset. The resulting datasets enable the consistent tracking of subdivision and development for all parcels over a given time frame. The process involved 1) dissolving and merging the 2005 digital Dane County parcel dataset based on contiguity and name, 2) further merging 2005 parcels based on the hard copy 2005 Plat book, and then 3) the reverse chronological merging of parcels to reconstruct previous years, at 4-year intervals, based on historical plat books. Additional land use information such as 1) whether a structure was actually constructed (using the companion digitized aerial photo dataset), 2) cover crop, and 3) permeable surface area, can be added to these datasets at a later date.
