Quarter-Quarter/Lots and Tracts
Tobin SuperBase™ Lots and Tracts is a quarter-quarter and lots-tracts data layer for the Public Land Survey System (PLSS). This layer cuts and subdivides the PLSS as depicted by SuperBase™ into a sub-section level of grid. The product is based on the SuperBase® Landgrid and Survey Data is initially separated into two layers of data:
- The Quarter-Quarter layer takes a PLSS section and quarters it into approximate 160-acre sections, and further quarters that result into approximate 40-acre quarter-quarter sections as well as standard lots.
- The Lots-Tracts layer includes non-standard lots and tracts. This layer also includes any lots and tracts created by grants or surveys. The Lots-Tracts layer is set up to emulate the lots and tracts found in the BLM data.
Coverage
Colorado, Idaho, Kansas, Montana, North Dakota, South Dakota, Utah and Wyoming
Data Creation
Tobin utilizes its previously defined data hierarchy and invokes national mapping data standards to homogenize the data into a consistent and structured dataset across the entire region where this data exists. Tobin also verifies and rectifies the data on a case-by-case basis to existing shelf orthophotography and any additional orthophotography and/or satellite imagery that becomes available now or in the future.
