EuroSDR project: Radiometric Aspects of Digital Photogrammetric Images

Project proposal May 2008 – Objectives – Project realization – Timetable– Project participants – Contact – Project progress

Objectives

• Improve knowledge on radiometric aspects of digital photogrammetric cameras
• Review existing methods and procedures for radiometric image processing
• Compare and share operative solutions through a comparison of these techniques on a same test data set
• Analyse the benefit of radiometric calibration and correction in different applications (classification, quantitative remote sensing, change detection etc.)

Project realization

Phase 1 – Review

Focus on the methodology itself. Report will be compiled based on literature research and query to sensor manufacturers, image providers, and image users.

• Query
• Short summary of the results
• Complete results (in preparation)

Phase 2 – Empirical study

The empirical investigations will focus on the processing of real data by test participants. Central research issues:

• Sensor radiometric calibration
• Image radiometric correction: restoration, pan-sharpening, tonal transformations, enhancement
• Radiometric processing chains: default processes of sensor post-processing software and methods of the test participants
• Applications (e.g. automatic classification)

Final analysis is performed by FGI and ICC.

• Emperical data description

Contact

The project is headed by
Eija Honkavaara and Lauri Markelin, Finnish Geodetic Institute (FGI)
Roman Arbiol, Institut Cartogràfic de Catalunya (ICC).

All activities in the project are aligned with the EuroSDR project “Medium Format Digital Cameras” under leadership of Görres Grenzdörffer, University of Rostock and the EuroDAC initiative on digital airborne camera certification, headed by Michael Cramer.

Project participants

National mapping agencies, camera manufacturers, software developers, mapping companies and research organisations are all welcomed to participate the phases 1 and 2. The FGI and the ICC will analyse the obtained results and compile the reports on the activities.

Project progress

• Official launch at the 112th EuroSDR Science Committee Meeting,14th-15th May, 2008, Oslo, Norway
• Project status report 26.9.2008
• Query distributed to sensor manufacturers and data providers on 1.10.2008
• Project status report 28.4.2009
• Short summary of the results
• Emperical data description
