Abstract:
These data represent those lands on the BLM Arizona Strip District that contain at least two of the three indicator wilderness characteristics: naturalness, solitude, and primitive/unconfined recreation. They were developed from the base layers of the those data sets, which are: wild_nat, wild_sol, and wild_primrec.
These data were compiled as part of an inventory procedure for the Bureau of Land Management, Arizona Strip District Draft Environmental Impact Statement (November 2005). The official manual for wilderness inventory, Wilderness Inventory and Study Procedures Handbook (H-1630-1), was rescinded September 29, 2003 by Bureau of Land Management (BLM) Instruction Memorandum 2003-274, BLM Implementation of the Settlement of Utah v. Norton Regarding Wilderness Study. Instruction Memorandum 2003-275, Change 1, Consideration of Wilderness Characteristics in Land Use Plans, was issued on October 23, 2003 and is the sole guidance for the consideration of wilderness characteristics in the land use planning process. These data were developed to meet the requirements of Instruction Memorandum 2003-275, Change 1. |

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

For regional analysis and display at 1:45,000. This dataset was prepared/acquired for use in the ASDO resource management planning process. These data establish a layer that spatially represents those acres on the Arizona Strip District that represent lands with wilderness characteristics. This layer was established as part of the Arizona Strip District DEIS in an effort to analyze a wilderness proposal submitted by the Arizona Wilderness Coalition.
Dataset locally known as lwc. This dataset and other datasets in the Arizona Strip District Office Geographic Information Database (ASDOGID) represent data for the BLM Arizona Strip District Office, and may include the Arizona Strip Field Office, Vermilion Cliffs National Monument (VCNM) and/or the Grand Canyon-Parashant National Monument (GCPNM or PARA). The Grand Canyon-Parashant National Monument is managed jointly by the BLM and the National Park Service (NPS).
ground condition
This data should not be used at a scale larger than 1:45,000. The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending on the data and method of acquisition. This data is suitable for regional planning, management decision support at intermediate scales (i.e. 1:45,000 or smaller), and cartographic purposes. The data is not suitable for analysis at scales larger than 1:45,000. If the Receiving Agency (RA) has modified the data in any way, they are obligated to describe the types of modifications they have performed on hardcopy maps utilizing the data. RA specifically agrees not to misrepresent ASDOGID datasets or to imply that any changes made were approved by BLM ASDO or NPS. No warranty is made by the BLM/NPS for use of the data for purposes not intended by BLM/NPS. This information may be updated without notification.

Feature attributes were taken from source material. Code assignments are believed to be representative of the source document.
Data was reviewed for correct topological structure. Duplicate lines have been removed.
This dataset covers the entire BLM Arizona Strip District. It is constantly being reviewed and added to as additional information becomes available.
The data was developed by screen digitzing polygons using a variety of field maps, photos, and other data sets. Coarse polygons were drawn in the field on maps printed with land status, transportation, and 1:24,000 or 1:100,000 digital raster graphs (DRG). These field maps were drawn to correspond with the wilderness characteristics evaluations that were written while in the field. In the office, information on the field maps was screen digitized using the same data sets in the background that were used in the field maps. Horizontal accuracy is not greater than 1:45,000. Positional accuracy was tested by visual comparison of the source data with the hard copy field maps.
Field data collected and presented by the Arizona Wilderness Coalition (AWC) were reviewed.

Field trips were made to evaluate the AWC proposal. Notes were taken, photos were taken, and evaluations were written.

In the office, polygons were screen digitized to correspond with the field collected data. Three separate data sets were developed that represented the three wilderness characteristics of naturalness, solitude, and primitive/unconfined recreation. These three data sets were then used to create the "Lands with Wilderness Characteristics" (LWC) data set. New polygons were created in the lwc data set if there were overlapping polygons from at least two of the three wilderness characteristics data sets. If the overlapping polygons were not coincident, in most cases the outermost boundary was used.
