OSL Staff Support Ongoing Research Requests

By • Mar 18th, 2011 • Category: Highlights

One service that the USGS Optical Science Laboratory (OSL) provides is researching historic calibration and aerial mapping project information for users from across government, academia, and industry.  These requests for information come from users of film aerial imagery who need information regarding the camera used to generate the film imagery obtained from USG or other archives.

In a typical week the OSL staff support 10 – 15 requests for assistance from a broad variety of users.  However, examples of this week’s requests were from a USGS glaciologist, the California Department of Transportation, an environmental remote sensing company from Virginia, a mapping company in Nevada and a researcher from the University of Wisconsin who asked for assistance with film imagery from the 1930s.  OSL staff report that in recent months there has been great interest in imagery over Antarctica and Alaska, two regions where USGS aerial imagery is in high demand for historical trending of environmental change.  For more information, please contact Scott Stephens at the USGS OSL 703-648-4692 or the RST Project Manager Gregory L. Stensaas, 605-594-2569,

is Web administrator for the RST site. Please email with any questions or concerns.
