USER NOTES:
A note concerning data scale: The digital data sets are used to create electronic and hard copy maps of the Breeding Bird Survey routes. The data can be used to conduct geographic analysis on national and large regional scales. The data should be displayed and analyzed at scales appropriate for 1:100,000-scale ata. No responsibility is assumed by the U.S. Geological Survey or by USGS Patuxent Wildlife Research Center in the use of these data. Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at: http://www.geoplan.ufl.edu/education.html

DATA LINEAGE SUMMARY:
This data was originally released by the U.S. Geological Survey in 1999. Data was downloaded by GeoPlan in shapefile format from National Atlas website: http://nationalatlas.gov/atlasftp.html in 2001. The data was then clipped to the State of Florida, and projected to FGDL Albers HPGN. When received, data was in Geographic projection, Datum: NAD 83, Spheroid: GRS1980, Units: Decimal degrees.
