Data supporting the Oregon Breeding Bird Atlas
(see data files for a short introduction.)
File: ALLPLACE.TXT
General Description: This tells you all features in each hexagon or square that are shown on USGS topographic maps, and conversely, which hexagon(s) and square(s) are associated with a particular feature. The data were obtained from the 1995 USGS "GNIS" database. The geographic coordinates of each feature given in that database were overlaid by computer with the digital grid of hexagons and squares.

Although we have made the data from this project accessible to anyone,
all the time the authors spent administering this project, as well as time spent
computerizing, organizing, and documenting the data, was uncompensated.
Moreover, not every limitation of the data has been described.
For these reasons, we request that researchers who wish to publish
statistical analyses of these data please contact us first to discuss
the data and opportunities for joint authorship of resulting publications.
Furthermore, we again thank the Oregon Natural Heritage Program and the
USEPA for sharing with us some of the non-avian data sets.

Fields (6, comma-delimited):
Name of geographic feature
Type of feature
HexagonID
InSquare (X= feature is located in the square)
Latitude of feature
Longitude of feature
Note: This includes over 51,000 features. Many (like named streams) cross several hexagons, but usually are listed only in one hexagon. For updates and more information on rules that USGS used to assign one set of coordinates to each feature, see http://mapping.usgs.gov/www/gnis/
