This data set contains polygons that represent quarter quarter sections. In 1985, Ramsey County began a 5 year project to modernize it's land records mapping system to create a computerized Land Information System. As part of the project, the County developed an accurate coordinate control base for this mapping system. The 27 existing State and Federal first order accuracy positions in Ramsey County were densified by a GPS (Global Positioning System) Network of 171 second order accuracy positions. These positions were established and recorded on existing public land survey corner monuments and accessory monuments through out the county.

This layer is a component of Natural resources interactive map.

In 1986, parcel polygons [PARPOLY] were digitized from hand drawn 1:2400 half and 1:1200 quarter section maps. In 1995, the parcel data layer was converted to an ArcINFO format and held in an ArcStorm database. Parcel polygons were converted in 2005 to an ESRI ArcGIS SDE GeoDatabase; the name was changed to Parcel Components. In 2014, Ramsey County migrated to ESRI's Parcel Fabric; Conveyance Divisions were created from the Parcel Components.
