Title: Area of Critical Environmental Concern (ACEC) - Designated
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This data set contains polygons that portray Areas of Critical Environmental Concern (ACECs) on public lands in Alaska. ACEC designations highlight areas where special management attention is needed to protect, and prevent irreparable damage to, important historic, cultural, and scenic values, fish, or wildlife resources or other natural systems or processes; or to protect human life and safety from natural hazards. ACECs are indentified, evaluated and designated through BLM's resource management planning process. Research natural areas (RNAs), outstanding natural areas (ONAs) and natural hazard areas (NHAs) are also categorized as ACECs.
Purpose:
To make ACECs available in a digital format (as polygons). Each polygon has a digital link to its' attributes (ACEC name, acreage, etc.). Attributes are stored in a data table, which is provided.
Supplemental_Information:
Mt Prindle RNA was adjusted in June of 2005. The RNA was adjusted to include sections 1 and 2, and portions of sections 3, 10, 11 and 12 of Twp. 7N 6E F.B.M. Nov. 2006 Indian River ACEC and Nulato Hills ACEC adjusted - adding acreage. Jan. 2006 - the following ACECs were adjusted - adding acreage - Nugget Creek, West Fork Atigun, Galbraith Lake and Nigu/Iteriak.

Use_Constraints:
This data is NOT survey quality and is not intended for measurement use.
ACECs were digitized from georeferenced maps of various types and scales. Accuracy of the data depends on the accuracy of the georeferenced map. Georeferencing of some maps may have been adversely affected, due to distortion introduced when the maps were duplicated - many of the maps provided for digitizing are photo copies of the originals.
Any hardcopies or published datasets using these data shall clearly indicate their source. Any users wishing to modify the data are obligated to describe the types of modification they have performed. User specifically agrees not to misrepresent the data, nor to imply that changes made were approved or endorsed by the Bureau of Land Management

This data has been visually inspected at the "each polygon" level. Beyond the inspection of the digital records, the accuracy depends on the accuracy of each georeferenced map as well.

Polygons were screen digitized from multiple georeferenced maps that had been photocopied before scanning and may have had distortion introduced in the copying process. The photocopies were the best available data at the time of this project

Process_Description:
Areas of Critical Environmental Concern (ACECs) were presented for digitizing as hand drawn outlines, on multiple maps of various types and scale. The ACEC outlines are generalized portrayals of geographic areas that often, but not in all cases, follow a watershed boundary.
Maps were scanned, at 400 DPI, georeferenced using ARC/GIS Software and saved as geotif files. The geotif files were imported into ArcMap. The ACEC outlines were screen digitized (creating a polygon layer), using ARCGIS/ArcMap Software.
During digitization, the outlines of the ACECs on the scanned maps were adjusted to reflect changes in land status since the ACECs were originally designated . ACECs exist on Public Lands only. Since the original ACEC designations were made, some lands within ACECs have been conveyed, tentatively conveyed or interimly conveyed to the State of Alaska or to Native entities. These lands are no longer Public Lands and as such are not included within the ACEC.
Land status used to adjust the ACEC outlines was obtained from the Bureau of Land Management's (BLM) Genstat/Land Status Database. Genstat/Land Status data originates in the BLM's Alaska Land Information System (ALIS). The Land Status attributes are a snapshot of the Land Information System Database and are only as accurate as that database. The data is produced to the section (square mile) level. Data from the Dec. 2003 Genstat/Land Status database was used to adjust the ACEC outlines. See the Feature Attribute Table for list of adjusted ACECs.
All but 2 ACECs were digitized by the Alaska State Office. These 2, George River ACEC and Oskawalik River ACEC, were digitized by the Anchorage Field Office and supplied as shapefiles to the Alaska State Office. The shapefiles were appended to the Alaska State Office ACEC polygons, to form a complete polygon layer.
This data is NOT survey quality and is not intended for measurement use.

Process_Description:
Process_Description: Updates were made to include all BLM-Alaska ACECs. A thorough review of all BLM-Alaska land use plans was completed to ensure all ACECs included were validly designated. The George River ACEC and the Oskawalik River ACEC were found to be invalid; therefore, they were removed from the data set. The data for the three ACECs designated in the Southwest MFP, the Anvik River ACEC, the Kuskokwim River ACEC, and the Southwest Peregrine Falcon Habitat ACEC, was created using the hard copy maps included in the plan. Due to the lack of quality of Southwest MFP maps, the data for these three ACECs generally reflects a one-mile buffer placed around marking on the maps, which depict the intended locations of the ACECs. No digital data previously existed for these three ACECs. The Anvik River ACEC, the Kuskokwim River ACEC, and the Southwest Peregrine Falcon Habitat ACEC were the only ACECs that did not have previous digital data to reference.

Attribute:
Attribute_Label: casefile_no
Attribute_Definition:
The number that refers to the serialized case file number of the group of official documents that record the facts, or actions taken, on a specific application, such as an oil and gas lease, exchange, airport lease, easement acquisition, etc. (CMR). This field should be in uppercase (for example, OR035582). This is a BLM International Organization for Standardization (ISO) assigned number used for identification of all lands and minerals case files including ACECs. This is the link to the LR2000 database. N/A - Not Applicable is the default code and will be used when no casefile number has been assigned. A value of "UNK" indicates unknown.

Attribute_Label: acec_est_acr
Attribute_Definition:
The measure of the area estimated in the designation process for land use planning. This is the designated size (acres) and may be different than the actual area. This does not change. Acres are calculated using the following formula: [Acres = Area (in meters)/4046.87]. This may be different than the GIS calculated area of the ACEC polygon. This field value should be the same for each polygon in an ACEC comprised of multiple polygons. The values in this field do not change. Do not use this field to derive GIS acres.

Attribute_Label: gis_acres
Attribute_Definition:
This is a calculated value of area in units of acres based on the area field created by default within the ESRI Polygon data structure. For the purposes of a 'national data layer', the data are to be stored in geographic coordinates which do not correspond to ground values. This requires that there be a standard method for calculating this attribute. The method used for these data are as follows: The data are projected into a standard projection such as the ESRI default Albers projection for the continental United States, "US Albers NAD 1983." Once the data are projected, then a calculation of "SHAPE_Area (square meters) * 0.0002471044 = acres" is applied to the existing 'area' field that is default area created by the ESRI software resulting in the field (Attribute) 'SHAPE_Area'. Please note that the figure used in this calculation is the factor for converting the US Survey Foot value of for the length of a meter as opposed to the International Standard for converting meters and feet.

Attribute_Label: admin_st
Attribute_Definition:
An administrative unit that identifies the state or geographic area which has administrative jurisdiction over lands, and cases, although the land for a case may not be physically located in a state. Only those states that are BLM administrative states are in the domain for this entity.
