Sensing Calibration and Quality Assurance
Commercial Remote Sensing (CRS) Characterization, Calibration,
Verification, and Validation (C2V2)
May 26, 2004
Background
USGS Geography Discipline mission is to provide quality cartographic information for the United States
Responsible for calibration of airborne film mapping cameras
Recognized as a Center of Excellence by the National and International community
1952 - Multi-collimator built by National Bureau of Standards 1973 – USGS Optical Science Lab begins camera calibration 2000 - ASPRS panel of experts recognized the need for digital camera calibration
Background (cont.)
2002 - USGS HQ Commercial Imagery Project established, Dr. Lee pushing calibration requirements, the project is currently called CRS C2V2 Project
2003 – USGS EROS Data Center (EDC) digital camera calibration cage and software established
2003 – USGS w/NASA Stennis perform in situ evaluation of digital mapping sensor vendors
2003 – CEOS/ISRPS Joint Task Force on Calibration/Validation, developed Cal Val Terms of Reference
2004 – USGS EDC established an in situ range to compare/characterize digital sensors
ASPRS 10 Year Forecast
“…Industry members hold an optimistic view of the future industry growth, estimating that it will increase by 9 - 14% per year.” Estimated Aerial Sales (approx.): 2004 - $2B, 2010 - $4B Estimated Space Sales (approx.): 2004 - $1B, 2010 - $2B
“The development of new analytic methods and new geospatial technologies will lead to future growth, … Data customers especially desire higher resolution and improved positional accuracy.”
“Federal government policies . . . have had a major influence over over the development of the market for remote sensing data, new technologies and other applications within the geospatial industry.”
C2V2 Project Mission and Tasks
Support government & science user mapping mission requirements Support a broad range of airborne & satellite CRS data sources
Systems and sources must be adequately characterized so the data can be reliably used
Analog Camera Calibration - OSL Operations and Maintenance Perform analog film camera calibration and certification
Digital Camera Characterization and Calibration (Lab and In Situ) Partner with Federal, State, and Local agencies, industry, and
academia in understanding digital camera cal val processes Expand and develop calibration laboratories, in-situ test ranges,
methodologies, and develop cal/val software Continue data access and procurement of CRS data sets
Remotely Sensed Data Procurement Procurement, and data sales services and provide system level
evaluation of the contractor products
C2V2 Project Mission and Tasks
Remotely sensed data, the quality of the data, and utility of data must be established for the community and The National Map System Characterization/Calibration and Product
Verification/Validation Provide independent system characterization, product validation, and
utility/application development/assessment of satellite and aerial based mapping sensors and products
Create a coordinated center of excellence for Land Remote Sensing Data within USGS and the community
Instrumentation and In Situ Calibration Range Support and Analysis Provide instrumentation and analysis support in accordance with
established interagency agreements with NASA, NOAA, USDA, and other USGS groups.
Analyze, establish, maintain in-situ test ranges
C2V2 Project Mission and Tasks
Digital Imagery Policy and Standards Development Partner with Federal, State, and Local agencies, industry, and academia
in developing, testing, and implementing advanced techniques, policies, and standards
Develop digital camera calibration policies and standards Support The National Map Quality Assurance Program Provide support for the development, transition, and implementation of
system data quality requirements and applications for TNM National remote sensing policy in support of the civil
community Combination of System Characterization and Policy Development
Tasks Support the CRS Space Policy Implementation Project with respect to
C2V2 and Joint Agency Commercial Imagery Evaluation (JACIE) Calibration support for future systems; i.e., LDCM

USGS Research of Digital Sensors
Lack of knowledge about calibration procedures different system designs different procedures used from manufacturers
Complete system has to be considered multi-sensor system installations (i.e. GPS/inertial
components) calibration process under review
laboratory calibration and calibration by users/certified sites using test field calibration procedures
Establish test sites for evaluation of digital camera products Goal: Does data meet contract requirements and standards
Digital Sensor Calibration Assessment
Development of policy and standards required Development and testing of procedures required
In situ calibration testing Self-calibration solution to increase flexibility Calibration evaluation software, training/documentation necessary Recommendations on calibration flight and process design
Assess geometry, radiometry and spatial quality Assess stability and repeatability aspects Perform laboratory comparison Processing effects on data products; re-sampling
Calibration Implementation Plan
The USGS understands the importance of national data completeness, consistency, and accuracy
Characterization and calibration is key to consistent and accurate data
To ensure quality of digital mapping data, we must: Develop policies and standards Standardize Government contract Statements of Work Devise and implement quality assurance procedures Promote process certification criteria for providers Work with Federal and State organizations via ASPRS, digital
sensor calibration consortium, and Mapping Partner Offices
EuroSDR network Digital Camera Calibration briefing
European Spatial Data Research 18 country network pushing for digital camera calibration
Concerted integrated effort
Michael Cramer (Project leader), Institute for Photogrammetry (ifp) – University of Stuttgart
“There is a definite need to deal with calibration tasks” “Does standard calibration fulfil digital sensor needs?” International community has the same questions and
issues with digital system calibration and product validation
JACIE
Joint team - NASA, NGA, and USGS Formed to leverage government agencies' CRS data
characterization capabilities Each agency purchases/uses commercial imagery to support its
research and applications. Data accuracy and utility assessment is critical.
Analysis of IKONOS, SPOT, QuickBird, L-7, ORBVIEW Comparison with high resolution aerial data USGS established partnerships with local governments to
evaluate usefulness and application of JACIE imagery Results: Presented at JACIE workshop, USGS Open File Report,
NASA and NGA reports, JACIE journal papers, 8-10 November 2004 - JACIE 2004 Workshop at USGS HQ in
Reston, VA
Consortium Development Strategy
Establish a North America Digital Sensor Data Consortium Include Federal Civil and Military agencies, academia, and
industry Use ASPRS and CEOS groups for support
In close cooperation with EuroSDR and other international activities Use CEOS/ISPRS Forum and Task Force
Panel on digital sensor calibration and product validation standards
Panel on establishment of international test ranges develop range standards and available ranges
