This is a Vector data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest .1
Ordinates (y-coordinates) are specified to the nearest .1
Planar coordinates are specified in meters
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.
The flattening of the ellipsoid used is 1/294.98.

MMTTT.TDRRR.RESS__ | MTRS is an 18-character field which is a concatenation
of meridian (M), Township (T), township direction (D),
range (R), range direction (E), and section (S). The form
of the field is MMTTT.TDRRR.RESS__. The last two spaces
were included in the beginning of the study but were not utilized.
MM = the FIPS code for meridian. FIPS stands for the Federal Information Processing Standard. The codes for the meridians are: 14 - Gila-Salt River 22 - Navajo TTT.T = BLM Township designation as 'TTT.T' may include a fraction of a Township. For example, Township 1 would be '__1.0'. Township 27.5 would be '_27.2'. The '.2' is a 1/2 township. D = BLM Township direction may be North (N) or South (S). RRR.R = BLM Range designation as 'RRR.R' which may include a fraction of a Range See Township (T) for example. E = BLM Range direction may be East (E) or West (W). SS = BLM Section number. For example, section 1 is '_1' and section 35 is '35'. Generally the highest section number is 36, but there are exceptions in several States. |

Cheryl Laudenbach, Denver Service Center, BLM, provided the original mining claim data from the Mining Claim Recordation Database. The data was used to create the mining claim density databases in OF 99-325.

The digital map was developed to document mining claim activity on federal lands in Arizona and to investigate interrelationships of mining claim activity with physical and social science concerns.
This digital map is not to be considered as a legal representation of survey lines and corners or of mining claim boundaries.

Data sources used in this process:
OF 99-325 reports that the attributes of the mining claim data from BLM
data, claims per section, do not represent the exact number of claims in
each section. Some claims overlap into adjoining sections and/or
townships. In order to count each claim only once, it was necessary to
choose one section for each claim to be identified with. Therefore, the
first section listed in the BLM database for a particular claim was
chosen as the section the claim was counted in.
The accuracy was tested by summing each category of claim in the mining
claim database and comparing the sum to those from the original BLM
database. The sums for each category matched.
No attempt was made to determine the accuracy of BLM's database.
A claim may be within a section or it may straddle two, three, or four sections. In order to count each claim only once, it was necessary to choose one section for each claim to be identified with. Therefore, the first section listed in the BLM database for a particular claim was chosen as the section the claim was counted in.
None of the data from BLM was omitted. The data is considered complete
for the purpose of determining mining claim density in this State.
The digital PLS of Arizona is assumed to be complete although it does
not cover the entire state.
The data set is a derived subset of the original BLM data. No
modifications to the BLM data were made.
The PLS in this report is a derived subset of the original PLS. Only
those sections containing mine claim density data are included in this
report.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- Users should contact the BLM for current data. The U.S. Geological Survey makes no warranties related to the accuracy of the data and users are required to determine suitability of use for any particular purpose. This digital map is not meant to be construed as a legal representation of mining claim boundaries. The PLS digital map is from the Arizona State Land Department, Arizona Land Resources Information System. Users should contact them for a current digital pls map and metadata. The map should not be used at scales larger than 1:100,000.
The user must obtain current information on mining claims from the Arizona State Office of the Bureau of Land Management for the area of interest since the mining claim density data is not current. The information in the database does not provide the legal location or status of individual mining claims.
Any hardcopies utilizing this data set shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent this data set, nor to imply that changes they made were approved by the U.S. Geological Survey.
