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.
Sonoran Desert National Monument route designations and asset type descriptions for all alternatives. See attribute tab for more thorough descriptions.
For regional analysis and display at 1:24,000. This dataset was prepared/acquired for use in the PDO resource management planning process.
Routes will recieve a designation among the following for each alternative- Open to all uses, Administrative use only, Seasonally Closed (Either from Feb 1 to Sep 15, or Apr 15 to Sep 15), Limited to Vehicles 50" or Less, Open to Non-Motorized Use, or Closed to All Uses. Routes were also given an asset type among the following- Road- Either considered a primary or secondary road. Primitive Road- Either considered a secondary or tertiary road. Trails- Unpassable by vehicle, generally considered for non-motorized, non-mechanized use only. Primary Road - A regularly maintained route, paved or unpaved, wide enough for at least two vehicles to pass. Provides access between two major points. Serves a large area with many routes of lesser quality branching from it. Secondary Road - Paved or unpaved, a regularly maintained one- to two-lane route with routes of lesser quality branching from it. Connects primary roads and major points. Tertiary Road - Generally a two-track route that may or may not be usable by a two-wheel drive vehicle. Does not receive formal maintenance. Single-Track Route - A route up to 1/2 meter wide upon which all-terrain vehicles or trucks are not allowed. Way - A road-like feature used by vehicles having four or more wheels but not declared a road by the owner. A way receives no maintenance to guarantee regular and continuous use. Spur - A route that exists for a specific purpose, such as access to a specific use or feature. Uses can be recreational or commercial. Features include campsites, mines, or range developments. A spur route is connected to another road or route type. Reclaiming or Reclaimed (route) - A route that has had very little or no use, so that there is woody vegetation growing in the route that would be damaged by the passage of a vehicle. Erosion or vegetation may block the route and could damage a vehicle or cause it to get stuck.
This data should not be used at a scale larger than 1:24,000. 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. 1:24,000 or smaller), and cartographic purposes. The data is not suitable for analysis at scales larger than 1:24,000. 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 PDOGID datasets or to imply that any changes made were approved by BLM PDO. No warranty is made by the BLM for use of the data for purposes not intended by BLM. 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 Phoenix District. It is constantly being reviewed and added to as additional information becomes available.
The data has been vertically integrated to the Arizona BLM Geographic Coordinate Database (GCDB) and to 1:24,000 scale DLG base data, including transportation, hydrology, and powerlines where appropriate. Overall horizontal accuracy for this data is not greater than national mapping accuracy standards (NMAS) for USGS source maps. Snapping and coordinate shift tolerances were maintained at 0.01 meters or less through editing. Horizontal positional accuracy for the digital data set was tested by visual comparison of the source data with hard copy verification plots.

-Reclaiming [R] Has not been used enough so that there is intact woody vegetation growing in it that would be damaged by the passage of a vehicle. Erosion and vegetation may block way, cause vehicle to get stuck and/or cause damage to vehicle. Crew should use discretion in traversing such a route. Single Track [ST] Pedestrian, bicycle, motorcycle; trucks and ATVs are prohibited. Can be up to 50 inches (approximately 1.25 meters) wide. Tertiary_Road_Unpav [TRU] *default* Generally a two-track that may or may not be usable by a two-wheel drive vehicle. Generally, formal maintenance is not performed on this type of route. Secondary_Road_Unpav [SRU] Generally, a regularly maintained one-lane road, with other roads of lesser quality branching from it. Connects primary roads, and major points. Secondary_Road_Paved [SRP] A paved road that is not a highway, with other roads of lesser quality branching from it. Often not striped. Connects primary roads and major points. Primary_Road_Unpaved [PRU] A regularly maintained road wide enough for at least two vehicles. Provides access between major points. Serves a large area, with many roads branching from it. Primary_Road_Paved [PRP] Major/Minor highway. Provides access between major points. Serves a large area, with many roads branching from it.
Range from 0.5 to 30, in meters; *default* is 2.5, the width of most Tertiary Road Unpaved
Determines if route in wash
Kind of surface: Asphalt [A] Paved; Chip Seal [CS] Gravel material mixed with oil based substance; Gravel (Imported) [GI] Material was brought in from offsite; road bed can be raised; Gravel (Natural) [GN] *default* Surface is covered with natural gravel. Common in areas of decomposed granite and desert pavement; Soil [S] The term here is used in a generic rather than technical sense. It is the native ground composed of fine particles. Includes deep dust situations; Sand [Sa] Usually in routes in drainage bottoms; Cobbles [C] Large rocks generally 6" or more in diameter. Usually in routes in drainage bottoms; Rock [R] Generally less than 6" in diameter that is rough to drive on; usually on steeper slopes on mountains; Bedrock [B] Exposed expanses of bedrock, usually due to erosion on an unmaintained route or in a drainage.
Surface-Secondary, Kind of surface. Same as previous, in addition to -Dash [-] *default* Route Material in Primary category is sufficient description.
Primary Use, What is seen; not a formal designation. Types: Dash [-] Undetermined; 4WD [F] *default* Route is eroded and/or steep preventing two-wheel drive vehicles from using the road. Long-bed pickup trucks may run into trouble, especially crossing narrow washes; 2WD [T] All paved roads, most Secondary_Road_Unpaved routes, and a few Tertiary_Paved_Unpaved that are smooth enough for at least higher-clearance vehicles; Motorcycle [M] Can tell by tire tread and occasional broken accessory; ATV [A] Can tell from unique, wide tread; Bicycle [B] Can tell by narrow tire tread; Hiking [H] Single-track trails signed for hiking. Wilderness. Footprints present. Tread is often rougher than those used by ATVs, motorcycles and bicycles. Some motorized trails may also be in use by hikers; Equestrian [E] Horseback riding trails. Dung and hoofmarks often a clue.
Secondary Use. Types: See Use1
Tertiary Use. Types: See Use1
Use Level Observed/estimated from tread condition. Types: Heavy [H] Direct or indirect evidence of regular usage; Light [L] *default* Clear evidence of infrequent usage, in light of observed environmental factors; Non-Existent [NE] Generally for reclaiming roads, with rare exceptions for recently abandoned road; Undetermined [U] Observer unable to determine use level, due to solid rock surface or environmental factors (e.g. recent precipitation).
Road Number. Number of highway or designated route, such as those in National Forests.
Name, official or local or highway ro designated route
Initials of person gathering data.
Any comment that does not fit in other parts of the Menu. Use this field for observations that pertain to past maintenance on a particular route.
Describes maintenance needed. Generally does not apply to unpaved tertiary roads and single tracks. Types: Dust_Abatement [DA]; Shoulder Maintenance [SM]; Stripping [ST]; Washboard [WB]; Grading [GR]; Aggregate_Replace [AG].
Subregion of SDNM
ARS Assigned Route Number used throughout designation process.
Not yet assigned, part of implementation process.
Length of route or route segment in miles.
Name of route, officially or locally.
Existing route designation. Routes are either open or closed, and there are no asset types assigned to Alt A, since this is a new type of classification implemented in the planning process.
