Description:

Abstract:

This data set refines potential peregrine falcon nest habitat within the National Petroleum Reserve - Alaska (NPR-A), aids in the interpretation of nest site selection and potential habitat based on the surface geology and geomorphology of the region, determines the key characteristics for the selection of nest sites in known nesting locations relatively to optimal sites in areas without known nesting occurrence, and helps in developing strategies for detecting potential shifts in the distribution of potential nesting habitat. Components of the data development included conducting geospatial analysis using digital elevation models, high-resolution remotely sensed imagery, and geomorphology. This GIS dataset consists of 16,141 bluff features (extracted from 5m resolution IfSAR data) and provides information on spatial geometry, relational distance information, surface geology, and other important conditions.

Purpose:

This data was created to provide certain information about designated relatively small areas in the study area (the bluffs). Potential data application includes defining areas where certain species of raptors may nest based on certain characteristics selected out of the table.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attributes were created based on a technical classification and delineation process created in ArcGIS. Manual checks were done on the derived bluff polygon features, and their corresponding attributes, to make sure they matched terrain indices on the source imagery. No formal QA/QC processes were run.

Logical_Consistency_Report:

Users are advised to read the entity/attribute section descriptions of the metadata record carefully for specific use of value variations and definitions. In the distance fields, a value of 0 indicates that the bluff is overlapping or touching boundaries with the indicated feature.

Completeness_Report:

Data set is considered complete for the information presented, as described in the abstract. Analyses were conducted on all bluffs and then those with area of less than 225 square meters were removed from the dataset at the end of the process.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

No formal accuracy assessment was conducted. Bluff features are estimated to be accurate with a 1 map pixel variance range, meaning they are placed accurately give or take 5 meters.

Methodology:

Methodology_Type: Lab
Methodology_Description:

A classification system for identifying areas of higher probability of peregrine falcon and raptor nesting was developed using the provided IfSAR 2012 DTM data and a variety of tools in ArcMap and ERDAS Imagine.

Characteristics of peregrine falcon and raptor nesting habitats were defined for lacustrine bluff locations in the Arctic Coastal Plain of Northern Alaska. Measurements and analysis of lake bluffs where there were peregrine falcon nests observed included such things as bluff height range, distance from lake shore, distance to large water body, and distance to riparian areas. This article helped by directing scientists to some of the relevant characteristics.
