PLSS Quarter Quarter Sections GCBD is a polygon dataset. Second division (QuarterQuarter) data is commonly an aliquot part of quarter sections but could be a lot or other division. GCDB base attribute data was used to create the second division feature class.

Lots were dissolved to the section level. Survey_type: B (aliquot parts less than 40 acres) for geopolitical splits were attributed as Survey_type: A. This data is derived from the PLSS Intersected feature class of the Utah PLSS Fabric GISv2.3 2020. This layer is based on Geographic Coordinate Data Base (GCDB) coordinate data. The locations of Public Land Survey System (PLSS) corners, as represented in geographic coordinate pairs, were derived from a variety of source documents, which include U.S. General Land Office and BLM survey plats/notes, as well as survey data obtained from other U.S. Government agencies, private sector survey firms, and local governments. The attributes assigned to PLSS polygons were taken from the BLM's Legal Land Description (LLD) data set, contained within the Legacy Rehost for the year 2000 (LR2000) automated records system. The coordinate data was produced by using control stations of known location, with varying degrees of accuracy, from various sources which include but are not limited to; U.S. Geological Survey (USGS) topological quadrangles and other sources, National Geodetic Survey (NGS) and US Coast & Geodetic Survey (USC&GS) Cooperative Base Network (CBN) control, Federal Base Network control (FBN), and Continuous Operating Reference Stations (CORS), and Global Positioning System (GPS) data, which is then analyzed and adjusted in concert with official survey data for any given geographic area. This data is a useful representation of the geometry and topology of parcels contained within the PLSS, but its application is intended for mapping purposes only. The GCDB data is not a substitute for a legal land survey.

The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter x,y coordinate precision; 0.001 mile m coordinate precision). There are no constraints or warranties with regard to the use of this dataset. Users are encouraged to attribute content to UGRC. This statewide dataset is maintained by UGRC in partnership with the BLM and local government. The geographic coordinates and their associated products are NOT legal land survey records. The coordinates can NOT be used as a substitute for a legal land survey. They can be used for record keeping, mapping, graphics and planning purposes only. No warranty is made by the Bureau of Land Management for use of the data for purposes not intended by BLM.

Updates were made to Quarter Quarter Sections in Utah County to add quarter-quarter sections to areas that were not broken down less than the Section level. These are labeled as SECDIVTYP = Z and SECDIVTXT = Unsurveyed Unprotracted. They were added, using information from points collected by county surveyors, that is in the data and extrapolating information from adjoining sections wherever possible. They are still areas that could not be interpreted well enough and they were left empty, beyond the section level. In the future this data will continue to be carried in this feature class but not incorporated into the official PLSS Fabric.
