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.

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.

The Public Land Survey System (PLSS) or the Rectangular Survey System is used for over half of the United States. Each grid cell represents approximately 36 square miles. In creating the PLSS the government divided the land into Townships, each of which was to be 36 miles square (6 miles tall and 6 miles wide). The location of a Township is described by its position in relation to starting lines called Base Lines and Principal Meridians. A Township is identified by a Township number based on how far North or South it is from the Base Line, and a Range number based on how far East or West it is from the Principal Meridian. So a Township 3 position North of the Base Line and 4 positions West of the Principal Meridian is referred to as "T3N R4E". These townships would contain 36 Sections, each a mile square. These townships were to be oriented true to North/South, but because lines of true north eventually converge at teh North pole, it was impossible to keep the townships oriented and a square 36 miles. Because of this, Townships are rarely truly square. One the north and West side of Townships there are often tracts of land with unusual sizes. These are referred to as fractional forties and eighties.

Capa temática de las veredas de Cundinamarca que hace parte de la información generada en su momento por el DANE (2016) con base en la acopiada por la Agencia Nacional de Tierras para todo el país. Fue ajustada por la secretaría de Planeación de la Gobernación de Cundinamarca en 2018, con el fin de guardar correspondencia con los límites de municipios y departamentos generados por el Instituto Agustín Codazzi-IGAC.La información contempla la división político-administrativa de los 116 municipios que componen el departamento de Cundinamarca y fue extraída del archivo compilado por la Agencia Nacional de Tierras a nivel del país.

This layer consists of a 1:250,000-scale polygon coverage containing depth-to-bedrock estimates used in preparing the GCSM for Wisconsin. The primary source for this data layer is a 1973 map at 1:1,000,000 scale published by the WGNHS and USGS. Where more recent information was available, the USGS updated the 50-foot and 100-foot contours of the depth-to-bedrock map at a scale of 1:250,000. Soil associations data, and other information,were used to add a 5-foot contour to the data layer.See the usage documentation (https://www.arcgis.com/home/item.html?id=e1e89ae505594459a46407f1daf4ad5d) and the Full report (https://www.arcgis.com/home/item.html?id=fd4d0c43abc04b4ab915586d9a0e89dd) for more information.
