Breeding Bird Survey Routes of North America: Map Layer Description File

This map layer portrays the current routes used for conducting Breeding Bird Surveys in the lower 48 States. This data set was collected using a different roads file from that available through the National Atlas of the United States, so there may be positional differences between the two map layers.

The North American Breeding Bird Survey Routes map layer was compiled by USGS Patuxent Wildlife Research Center.

Metadata

What follows is very detailed technical information about this map layer. This is often called metadata. Metadata (or "data about data") describe the content, quality, condition, and other characteristics of data. Metadata are used to organize and maintain investments in data, to provide information to data catalogs and clearinghouses, and to aid data transfers. The Federal Geographic Data Committee (FGDC) publishes the Content Standard for Digital Geospatial Metadata. Many organizations within and outside of the federal government have adopted the FGDC metadata standard and are using automated indexing and serving mechanisms to provide access to their holdings through the Internet. Visit the FGDC Clearinghouse to learn more about how metadata is used in clearinghouses and to search for other data sets.

Description:
Abstract:
This data set portrays the current routes used for conducting Breeding Bird Surveys in the lower 48 States.
Purpose:
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 data. No responsibility is assumed by the U.S. Geological Survey or by USGS Patuxent Wildlife Research Center in the use of these data.

Native_Data_Set_Environment:
UNIX-ARC/INFO Version 7.1 single precision


Data_Quality_Information:
Logical_Consistency_Report:
Arc/INFO software was used to create and maintain topological relationships Between features. The Arc/INFO command BUILD was run to ensure the topological consistency of the data set. Each route was checked for missing and dangling arcs, correct length, proper direction, and correct route measures.
Completeness_Report:
This data set contains the Breeding Bird Survey Routes in the lower 48 States which were considered active in 1998. This includes many of the routes added in 1998, though not all of them. The discontinued Breeding Bird Survey routes were generally not digitized.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal positional accuracy was tested by visual comparison of electronic maps to the source materials. For a few routes, we verified positions using GPS.

If the route did not start at an intersection, the starting point may be slightly off. Portions of the route are sometimes skipped because of traffic noise or overlap with other routes. These skipped portions are usually not indicated.

The maps we used did not always indicate the exact ending points of the routes, so in many cases the ending points are estimated and the routes digitized are longer then the actual route run.

Occasionally portions of the roads on which Surveys were conducted were not contained on the digital road files we used. For these cases the road locations were very roughly estimated.

Process_Step:
Process_Description:
The Breeding Bird Survey route maps (BBSMAP) for most States were digitized with ArcView 3.0 and the US Streets Database (ESRIDA), which is based on the Tiger files. The arcs forming the routes were selected and shape files were created for each route. Routes in Idaho, Michigan, North Dakota, Ohio, West Virginia, Washington and part of Maryland were digitized using DeLorme's Street Atlas USA (DLRM). The files were converted to Arc/INFO line coverages by State.

BBS routes for Minnesota and Wisconsin were digitized by James M. Sales, University of Minnesota, Duluth, UMD Natural Resources Research Institute, Duluth, MN, 55812. The Virginia routes were provided to us by Jeffrey B. Trollinger, Fish and Wildlife Information System, Virginia Department of Game and Inland Fisheries, 4010 West Broad Street, Richmond, VA 23280. The California routes were provided to us by Allan Hollander, University of California, Santa Barbara, Santa Barbara, CA, 93106. The data was then converted into a format consistent with ours. We used ArcView to add newly created and missing routes to these files.

For each State, an Arc/INFO route system was added using the Arc/INFO MEASUREROUTE command. The JOINITEM command was used to add the route name from the BBS Database (BBSDA). The APPEND command was then used to create a single coverage for the National Atlas.

Process_Step:
Process_Description:
The coverage was read into Arc/INFO, converted to NAD 83, and converted from the Lambert projection to geographic coordinates. The resulting file was loaded into ArcView with the route system information as one shapefile and the breeding bird survey route arcs as another shapefile. To create a final file containing both the arc information and the route lengths, the tables for the two layers were joined using the rteno item, and the two ID numbers from the route coverage were turned off. The resulting file was saved as a shapefile.
