SGID information and Changes
New: 100K and 250K USGS Topographic DRGs Download Indices PDF Print E-mail

Written by AGRC Administrator,

Backed by popular demand, we now have index pages for downloading scanned USGS topographic maps (DRGs) at 1:100000 and 1:250000 scales.

These new indices are accessed from the same page as the 1:24000 scale links:

In addition, AGRC will have a browser-based interactive map to download all file-based raster data in the near future.

Major Revision: Utah State Land Ownership Data Layer PDF Print E-mail

Written by Jessica Kirby,

 Land Ownership Revision (October 2008)

The State of Utah Land Ownership GIS data layer is now vertically integrated with the SGID currently published GCDB reference lines (November 2006).

Please review the metadata process steps for details about the integration process. During the integration, a statewide surface ownership verification was preformed, township by township., by cooperating State and Federal Agencies.

Please contact the State of Utah School and Institutional Trust Lands Administration (SITLA) GIS Department ftp://lands-ftp.state.ut.us/pub/contacts.htm for more information regarding this revision.
 
Key Features of the Revision

  • Vertical integration with the Bureau of Land Management (BLM) Geographic Coordinate Data Base (GCDB). The GCDB is a collection of geographic information representing the Public Land Survey System (PLSS) and some Non-PLSS surveys of the United States.
  • Water and Intermittent water surface ownership class was removed and replaced with the appropriate surface owner.
  • Navigable waterways were given State Sovereign Lands status (some lands may be in question).
  • Non-navigable waters were split in half, at an approximate center line down the riverbed, and given the owner status of the adjacent lands.  
  • Navigable and Non-navigable waterways determination was provided by the BLM.
  • Parcel Designation detail was added to ownership were applicable  (For example, Private or Federal Lands that are Designated as a State Wildlife Management Area or State Park)
