ASPRSPanel on USGS Progress on Remote 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/valsoftware • 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
C2V2 Team • Phil Rufe/Mike Duncan/Tim Saultz • Mid-Continent Mapping Center • George Lee • Western Region Geography • Greg Stensaas, Ron Parsons, Jon Christopherson • EROS Data Center and SAIC • Jeff Sloan • Rocky Mountain Mapping Center • Jay Storey • Eastern Region Geography • NASA Stennis • Vicki Zanoni
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 USGS Research of Digital Sensors
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
