  • Web based GIS are used to publish cadastral data and land records in the most efficient way. Making data accessible to the user community is highly beneficial to the managing agency as well as the public. This presentation will demonstrate how the BLM’s National Integrated Land System (NILS) has evolved to meet the specific needs of the cadastral community by providing: • Free data distribution of cadastral data that can be consumed as SHP files, WMS (Web Map Service) and other formats • Easy access to detailed reports and information • Free survey data in many formats that can assist surveyors in locating monuments in the field • Complex web services that generate land descriptions or translate them to geometries • Powerful search tools to aid in land management decisions
  • Use Authorizations have been maintained in various forms but most recently published through LR2000 Case Recordation.
  • a.k.a. Cadastral Survey data Survey Type – Aliquot part, special survey such as mineral survey or homestead survey, unsurveyed, etc. Geopolitical – BLM District/Resource Area, County, Congressional District, and surface management agency Note: The surface management agency in LLD is coded as BLM, even when the land is privately owned, unless the land is located within a National Park, National Forest, etc.
