Disclaimer Regarding the Accuracy of the Aerial Photo Project Online Map Tool

Air Photos are not online

The Aerial Photo Project Online Map Tool is designed to help you determine whether or not the Map Collection, University of Washington Libraries has air photos for your place and time period of interest.  To view and make reproductions of the air photos you must visit the Map Collection.

Aerial Photo Projects: Approximate Coverage Areas

The areas highlighted in blue on this map show the approximate boundaries for the air photo projects held in the University of Washington Libraries Map Collection.  This tool is intended to help you determine the likelihood that there are air photos available for your area and time period of interest.  To determine whether photos are available for your exact area of interest, you must examine the photos on-site.  We are not able to provide services to identify and reproduce air photos for people who cannot come to our collection.  We hope that this tool will help you determine whether a trip to our collection is worthwhile.

For the majority of each area represented in blue on the map, we are very confident that there are air photos in our collection.  However, our confidence about the availability of air photos is weaker for those areas at the edges of each blue area.

Why isn't this online air photo finder 100% accurate?

The coverage areas shown in blue on this online map were created using GIS software based upon visual examination of the detailed flight line indexes.  Many of our flight line indexes overlay the information about individual air photos onto accurate maps.  However, several of our flight line indexes are photo mosaic images or handmade maps, created by visual comparison of the photos to topographic maps.  In these instances the accuracy of the coverage area as represented on the flight line index is an approximation.  Putting these approximated coverage areas into an online tool which is capable of pinpointing precise latitude/longitude coordinates, or township/range locations, implies an accuracy which does not exist.
