We have a variety of base and thematic data available for download via this web site, including elevation models, orthophoto quads in MrSid format, and DRGs for the entire state of Oregon.
The Libraries now offer GIS data distributed to public computers across the library system. We are striving to offer the most current version of our most requested data via this method.
Due to licensing restrictions and technical limitations, much of our data can only be distributed on disk. Assistance with finding and using data in our collections is generally available during regular business hours.
These maps do not necessarily have data for download, but are good examples of online tools developed to visualize a given set of themes, such as earthquake population change over time or natural disasters. Map Mashups are included here.
