1. ASPRS 2005 Annual Conference, Baltimore, Maryland Overview of USGS Calibration Activities U.S. Department of the Interior U.S. Geological Survey

2. ASPRS 2005 Annual Conference, Baltimore, Maryland ASPRS Camera Calibration Study Panel study completed in 1999 Study findings and recommendations: Standards development inherently governmental USGS should continue camera calibration USGS should develop methods for digital sensors

3. ASPRS 2005 Annual Conference, Baltimore, Maryland Analog camera calibration upgrades Analog calibrations performed on custom-built colliminator instrument since 1973 Over 100 analog calibrations per year Modified to accommodate super-wide angle lenses Lighting and electronics upgrade 2003 Evaluating alternatives for Kodak glass plates Will keep present analog calibration process operational for the foreseeable future

4. ASPRS 2005 Annual Conference, Baltimore, Maryland Interim Digital Capabilities Contract awarded to Pictometry to develop and build a laboratory calibration capability for small format digital cameras System delivered and operational at EROS Nat Calibration based on “cage”, Australis software, and the SMAC model Calibrations being performed on research basis

5. ASPRS 2005 Annual Conference, Baltimore, Maryland OSU In-situ Calibration Study Grant awarded to OSU in 2003 to develop software to perform in-situ calibration In-situ range established in cooperation with Ohio DOT Software delivered in 2004 and being tested Currently testing in-situ calibration methods Need to establish standards for in-situ sites and policy for in-situ calibrations

6. ASPRS 2005 Annual Conference, Baltimore, Maryland JACIE Activities Joint efforts by NASA, NGA, and USGS to perform characterization of commercial satellite products Space Imaging, Digital Globe, and Orbimage Annual JACIE Workshops to report system performance and applications by government, academia, vendors, and users

7. ASPRS 2005 Annual Conference, Baltimore, Maryland Extension of Stennis Test Site for Product Characterizations Stennis test range enhanced for airborne platforms and digital cameras Cooperative agreement with NASA to perform characterization of digital orthophoto products Geopositional accuracy and spatial resolution determination Acceptance letter and final report provided to vendor and posted on USGS Web site

8. ASPRS 2005 Annual Conference, Baltimore, Maryland IADIWG Formation Inter-agency Digital Image Working Group established by BOR, BLM, COE, FSA, FWS, NIST, NGA, NOAA, NRCS, USFS, and USGS Kickoff meeting held and charter being drafted “Broiler-plate” specifications, guidelines, and standards for digital image acquisition being drafted Host workshop to review initial draft Final draft by October 2005 and presented at ASPRS Pecora 16

9. ASPRS 2005 Annual Conference, Baltimore, Maryland Next steps Work with camera manufacturers to review and approval factory calibration methods Work with data providers on camera acceptance process and quality control guidelines Establish new policies on camera calibration for the United States Work with International groups Extend characterization methods to LIDAR and other sensors

10. ASPRS 2005 Annual Conference, Baltimore, Maryland Long-range Plans Evolve camera calibration, product characterization and quality checking into a quality assurance program for The National Map a nd USGS partners

11. ASPRS 2005 Annual Conference, Baltimore, Maryland Recall Spectrum: Camera certification System certification Product characterization Quality control of deliverables Approved processing methods Best practices by data providers ISO certification

12. ASPRS 2005 Annual Conference, Baltimore, Maryland Seeking ASPRS support Need to establish a formal certification process at several levels: Sensor manufacturers Sensor acceptance by data provider Monitoring Data provider’s best practices and processes to maintain system calibration Product characterization of products offered Guidelines for quality control of data and product deliverables
