Obtain the data on CD-ROM |
You can obtain a copy of this data on CD-ROM if you contact Rosana
Costello (rcostello@fs.fed.us),
GIS analyst at (541) 225-6383. There is a $40 charge if you request
the data on physical media.

What will I need to view the files? |
Many of these files are large, so please check the file
size listed before downloading. All data files have been compressed
with the Unix Compress utility. PC users can use a zip utility such
as WinZip or gunzip
to unpack these. Unix users should use the uncompress command.
You'll also need GIS software, available from ESRI,
to view the spatial data. Many other GIS and graphics software packages
have a utility to import *.e00 format files.
|
How old is this data? |
GIS information may be updated, corrected, or otherwise modified
without notification. We typically update the set of coverages on
the website twice yearly. Individual coverages have different update
strategies and cycles; some are more dynamic than others. If using
the most current data available is critical to your information needs,
please check with Willamette GIS (rcostello@fs.fed.us)
for the status of that coverage.

Welcome to the Willamette National Forest - Supervisors Office GIS Data
Dictionary. This page contains metadata, or data about data, for our spatial
data sets. The data sets are organized by theme.
For example, if you are interested in a data set that has to do with water,
just click on the water link in the table of contents. Then click on the
name of the data set of interest to view the data dictionary.
Each data dictionary will explain geographic information about the data
set, who the data steward is, how the data set was built, and other associated
information. It will also describe the database tables that are associated
with the data set. Please contact the data steward if you have questions
about the content of the data. Their phone number is included within the
data dictionary.
The digital data is available on line free of charge. Just click on the
Download link that is contained within the individual data dictionary.
The data is packaged in the following formats:
Spatial Data is provided in Arc/Info export format (*.e00). These
files can be used in Arc/Info, ArcView, or ArcExplorer GIS software packages.
ArcExplorer is a free spatial data viewer that can read Arc/Info data
sets. There is a free import utility that will import Arc/Info export
files. (ESRI.com). Many other GIS and
graphics software packages have a utility to import these files.
Tabular Data is provided in ascii delimited text files. These
files are delimited with commas, and text fields are double quoted. They
were built on a PC so they have a carriage return/line feed combination
at the end of each line. Unix users should import these via a PC based
program then export and transfer them via ftp to remove the linefeed character,
or use the dos2ux utility.
