ASPRS: The Imaging and Geospatial Information Society has posted to its web site the full text of the draft report of the Camera Calibration Review Panel and established a two-way on-line discussion forum to facilitate review and comment. This report posting and discussion forum supports the independent panel formed earlier this year as an advisory group to the United States Geological Survey (USGS) on the future of camera calibration and related issues.
The Camera Calibration Review Panel serves as an independent advisory group to the USGS. Convened with the assistance of ASPRS, the panel has reviewed a wide range of issues related to sensor calibration facing the geospatial community in the future. In addition to validating existing requirements for aerial mapping camera calibration in the United States, the panel has assessed future technical developments related to sensor calibration and identified operational strategies to address the long term viability of these functions in support of the broad user community.
An initial progress report was presented at the 1999 ASPRS Annual Conference in Portland, OR, in May, as part of two sessions on camera calibration issues. Both sessions were well attended, and the participant’s comments clearly confirmed the importance of calibration to the community. A draft version of the panel’s report is now available.
"ASPRS encourages you to review the report in its entirety, and submit your comments, ideas, and suggestions to the panel," said John Boland, panel chair. "The panel is intended to be independent – not isolated. It is your participation and comments that will provide the report the validity it needs to be of value to the USGS."
The report begins with the panel charge, then moves onto discussions of the purpose of geometric calibration and the need for standards and specifications. It reviews imaging technology developments, acceptance of those developments by the community, and trends in support systems. General calibration methods, current practices in the United States and the international community, and calibration infrastructure options are included. The report concludes with recommendations and suggestions for future research.
ASPRS Executive Director James R. Plasker stated, "While the subject report was prepared with the input of vendors and users from the private, government and academic sectors, it is important to obtain comment from as wide an audience as possible before the report is finalized. The panel presentations at the ASPRS Annual Conference in Portland were a good start. Now, using the web-based forum, we hope to gain additional review and comment on the draft report." The comment period is expected to last 60-90 days, depending on the volume of traffic.
