Bureau of Land Management, 20070921, Alaska Planning Boundaries (NAD83): BLM, Anchorage, AK.
This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000000000089. Longitudes are given to the nearest 0.000000000000089. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.
Sequential unique whole numbers that are automatically generated.

Coordinates defining the features.
The purpose is to have one dataset that depicts the current boundaries of all existing plans (including plans in the development phase).

Planning units were determined by the various Bureau of Land Management planning teams.
The horizontal accuracy is dependant upon the quality of the boundaries under which each RMP, MFP, or IAP were digitized.
Vertical accuracy was not assessed.
This dataset was originally created in a response to a data request by WO in 2000. The data has been updated as new plans have been established or as older plans have been amended.
This dataset contains a compilation of planning boundaries whose sources vaired. Originally, BLM established Management Framework Plans (MFP). Those boundaries came from data stored in the Alaska Land Information System. Most MFPs have been replaced by RMPs with the exception of the northern portion of the Southwest MFP. The RMPs and IAPs were created using a combination of 1:63,360 and 1:250,000 scale quadrangles. Additionally, the IAPs utilized portions of the Alaska Rectangular Survey Plat Process (ARSUPP) and the BLM Survey Plats. Since this data was to be primarily used for cartographic representation and not intense analysis it didn't seem inappropriate to mix the scales and source information. This data is best suited for viewing on a statewide level.
Are there legal restrictions on access or use of the data?
