PeregrineNestingArea is an ESRI SDE Feature Class showing Nesting Areas
for Peregrine Falcons in Colorado. Nesting Area is defined as an area
which includes good nesting sites and contains one or more active or
inactive nest locations. The boundaries are drawn based on professional
judgment to include most known nesting habitat in the vicinity. Usually
these areas are mapped as polygons around cliffs and include a 2 mile
buffer surrounding the cliffs.
This information was derived from field personnel. A variety of data
capture techniques were used including drawing on mylar overlays at
1:50,000 scale USGS county mapsheets and implementation of the
SmartBoard Interactive Whiteboard using stand-up, real-time digitizing
at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing
Mapping Resources. GeoWorld 16(3):32-35).
Dataset was acquired from a third party distributor who obtained it from CDOW in January 2011. The authoritative data source is available on ArcGIS.com (http://www.arcgis.com/home/item.html?id=8958b847140b402e9fba76540826395c) and will be updated from that location.
