GIS Data Center
Welcome to the GIS Data Center from the Washington State Department of Natural Resources (DNR). Here is where you will find natural resources and related data for use in your Geographic Information Systems (GIS) software. The data are free to download at no charge.
The datum for the Washington State Department of Natural Resources (DNR) Geographic Information System (GIS) data is North American Datum 1983 HARN (1991 adjustment). The data are registered to the Washington Coordinate System of 1983, South Zone. Units are in U.S. Survey feet.
Please note that if you are using data in other projections or in other units (e.g. meters) your data will not be spatially aligned to DNR GIS data.
The GIS data available from this site are produced in different file formats depending on the type of data it is and how it is stored here at DNR.
Determining Fitness for Use
Many geographic data sets in use at the DNR have been developed for a wide range of purposes. Please give careful consideration to the issue of "fitness" for a particular use. Metadata (information about the data) is available from this site to aid in this process. Please feel free to contact the specified Contact Person (listed in the metadata) if you have any questions about the dataset. Determining "fitness for use" is solely the user's responsibility.
The Washington State Department of Natural Resources (DNR) provides these geographic data "as is." DNR makes no guarantee or warranty concerning the accuracy of information contained in the geographic data. DNR further makes no warranties, either expressed or implied as to any other matter whatsoever, including, without limitation, the condition of the product, or its fitness for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers of DNR, no warranty, expressed or implied, is made by DNR regarding the use of these data on any other system, nor does the fact of distribution constitute or imply any such warranty.
File Size / File Compression
GIS datasets can be very large files that can take a long time to download. Because of the size, most of the DNR GIS files are provided in a compressed format. You will need to be sure your computing environment has enough memory available to handle the size of the file you are downloading. You will also need to have a software utility available to uncompress the dataset. NOTE: TAR files cannot be uncompressed using a WinZip utility. You will need to use a Gzip utility or another utility compatible with your system software.
Questions About the Data
Questions about the data provided at this site should be directed to the Contact Person listed in the metadata. There may also be contact information on the Program Website link provided on the Available GIS Data

Different file formats or datasets may download differently, depending on your computing environment. The majority of the files available are in the shapefile format.
See How-To Download Shapefiles
The download instructions will be similar for other file formats. You will notice some differences in how different file formats download, such as when the online data agreement will pop up, etc. The differences are slight, but cannot be avoided.
