Data Library Formats and Coordinate System Information
Viewing Files and File Formats
 
GIS data files are generally compressed with a zip utility.  Spatial Data Library data sets use the statewide projection standard endorsed by the Oregon Geographic Information Council.
 
After downloading the file:
  • UNZIP the file.
  • Load the data set  into a software program that recognizes the file formats.
If you do not have the required software, a free program, ArcGIS Explorer, can be downloaded from ESRI.
 
Data Library File Formats
  • Shapefile
  • ARC/INFO export file (e00)
