This data set is a result of compiling differing source materials of various vintages.Source material examples used to create and maintain dataset include: BLM 100k Subsurface Maps, Oil and Gas Plats, Coal Plats, Public Land Survey GIS Data (cadnsdi v.2.0), Field Office GIS Data, Compiled 24k USGS Maps, and Land Records.

This mapping application was designed for users to be able to access BLM Colorado's GIS data without the need for installed specialized software. The application will allow users to turn on and off layers based on individual needs, create pdf maps to save, review attributes for features within the datasets, change basemaps, make measurements and more. Changes to available layers may occur overtime. Generally, datasets are updated quarterly but see individual layer descriptions for more details.

BLM Colorado Roads and Trails on BLM managed lands. This data uses the national BLM Ground Transportation Linear Features (GTLF) standard allowing for the capture of data from the Travel Management Plan (TMP) as well as from observed route usage. Additional attributes were added for Colorado specific purposes. Routes for winter only activities are separated in a separate layer. Routes where electric bikes are allowed can be easily identified by turning on the highlighting layer.

Mobile Map Packages (MMPK’s) can be used in the ESRI Field Maps app (no login required), either by direct download in the Field Maps app or by sideloading from your PC. They can also be used in desktop applications that support MMPK’s such as ArcGIS Pro, and ArcGIS Navigator. MMPK’s will expire quarterly and have a warning for the user at that time but will still function afterwards. They are updated quarterly to ensure you have the most up to date data possible. These mobile map packages include the following national datasets along with others: Surface Management Agency, Public Land Survey System (PLSS), BLM Recreation Sites, National Conservation Lands, ESRI’s Navigation Basemap and Vector Tile Package.

Geodatabase Format - This line feature class represents the segments identified as eligible or suitable for Wild and Scenic River designation. These segments are part of the National Landscape Conservation System (also known as National Conservation Lands). The attributes for this feature class serve to store the feature level metadata information for the lines, as well as document the origin and characteristics of each line. Lines will be segmented when any of the attributes change (e.g. when the classification changes). The related table contains the outstanding remarkable value(s) identified for each segment.

BLM Colorado Lands Inventoried Lands for Wilderness Characteristics is consistent with Section 201 of the Federal Land Policy and Management Act (FLPMA), which requires the Secretary of the Interior to “prepare and maintain on a continuing basis an inventory of all public lands and their resource and other values,†and the BLM Land Use Planning Handbook, BLM Colorado has identified and begun an assessment of BLM-managed lands with wilderness characteristics outside of existing WSAs. BLM Manual 6310 - Conducting Wilderness Characteristics Inventory on BLM Lands, provides the guidance from which BLM Colorado performs the wilderness characteristic inventory process.

The attachment table contains the AppendixForm B for the LWC area. Not all areas have the attachements at this time but will be added in the future.

The purpose of this dataset is to show BLM Colorado Grazing Allotments, which are areas of land designated and managed for grazing of livestock. It may include private, state, and public lands under the jurisdiction of the Bureau of Land Management and/or other federal agencies. An allotment is derived from its pastures, where the grazing of livestock is occurring. Vacant allotments are shown in a separate layer. Verification of vacancy needs to be made with the respective field office. These vacant allotments are a subset of the Grazing Allotment dataset and were pulled from the Rangeland Administration System (RAS) as of 7/31/19.

This polygon feature class represents the spatial extent and boundaries of the BLM Colorado Recreation Sites. The general types of recreation polygon features targeted by this feature class include campgrounds, OHV designated areas, recreation management areas, natural/endangered areas, etc.

description: This data set represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The metadata describes the lineage, sources and production methods for the data content. The definitions and structure of this data is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data set is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully Intersected (all of the PLSS feature at the atomic or smallest polygon level), PLSS Townships, First Divisions and Second Divisions (the hierarchical break down of the PLSS Rectangular surveys) PLSS Special surveys (non rectangular components of the PLSS) Meandered Water, Corners and Conflicted Areas (known areas of gaps or overlaps between Townships or state boundaries). The Entity-Attribute section of this metadata describes these components in greater detail.; abstract: This data set represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys.

Shapefile Format- This data set consists of digital data describing BLM Coloardo's Administrative Unit Boundaries in the State of Colorado, also known as BLM Colorado Field Office Areas. This data set was derived from BLM Colorado Field Office data captured at a scale of 1:24,000 and joined into a resulting statewide map layer. Differences in data capture techniques resulted in the data editor dropping some boundaries from various Field Office Areas to avoid sliver problems. The data was snapped to the 2016 Geographic Coordinate Data Base (GCDB) for boundary consistency

A national BLM GTLF data standard is essential for collecting the landscape-scale data necessary to identify management opportunities and challenges that may not be evident when managing smaller land areas. GTLF data not only serve the crucial function of improving BLM transportation planning, but is also invaluable to numerous other BLM programs affected by transportation (e.g. water and air quality, wildlife habitat fragmentation, engineering, realty, cultural resources).

In the Public Land Survey System (PLSS), a Township refers to a unit of land, that is nominally six miles on a side, usually containing 36 sections. This dataset represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance.

Shapefile Format –The fully intersected data is the atomic level of the PLSS that is similar to the coverage or the smallest pieces used to build the PLSS. Polygons may overlap in this feature class.
