GeeseBroodConcentrationArea is an ESRI SDE Feature Class showing Brood Concentration Areas for Goose species: Snow Goose (Chen caerulescens) and Canada Goose (Branta canadensis) in Colorado. Brood Concentration Areas are defined as brood areas within production areas where geese traditionally congregate in high numbers. 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).
