These data contain the number of state mining claims, prospecting
sites, federal claims either selected or patented and totals
located within each section of the State of Alaska. A field also
provides a totals for all state and federal claims and sites.
To provide consultants, planners, and resource managers
with an indication of the type and number of claims or
sites, whether state or federal, which are located in a particular
area.

All codes are validated by the original records system. Codes are
verified against an acceptable list during processing in SAS. After tabular
data has been processed and converted for spatial use, maps are generated
for visual comparison. These maps are compared with previous year's maps.
Polygon topology present.
This data represents the number of claims located within a section.
Please refer to the relevant plat and legal documents for more specific
information about the type, status and specific location of claims or sites.
Accuracy is checked by visual review of hardcopy maps.

base data
Current BLM casetype, casestatus and land status information is
used to classify data extracted from federal land records which
is stored in an Informix based system known as the Alaska Land
Information System (ALIS). Questions about the data contained
in ALIS should be directed to the Federal Public Information
Center located in the Federal Building, Room 148 in Anchorage,
Alaska. The telephone number is 907-271-5960 (TTY - 907-271-5969).
A routine has been established and refined over time to extract
selected data and output it in a predefined format. The
resulting flat file, which contains 1 record per transaction,
is compressed.
The program run by BLM to extract lands status data for DNR is
known as DNRDUMP. BLM's Division of Support Services, Branch of
Information Technology Services, Application Services Section (
AK954), processes the data.
ADNR staff then ftp the compressed file to working space on
their UNIX based network. The data is summarized by case to
arrive at counts for the number of cases within each Meridian,
Township, Range, Section MTRS. (Cases are state claims or sites
and federal patented or selected claims.)
ADNR's data is extracted from the Land Administration System (
LAS) data warehouse to a flat file. Casetype, casestatus and
land status is used to select and classify extracted data.
BLM and LAS data are processed by ADNR using SAS. Both BLM and
DNR data are processed by MINFEFS.SAS. While distilling the
BLM data to the section level some of the tables contained in
BLMFMTS.SAS and LASFMTS.SAS are used.
The summary results create a dataset with one (1) observation
per section. This dataset is related to the Section coverage in
Arc/Info and used to reselect those sections containg any
mining data. All attributes from the file are inserted into
the coverage's polygon attribute table.
In Arc/Info (current version 7.1.1) the newly generated section
level coverage is dissolved on all attributes in the coverage.
