• Classification of digital cameras (photogrammetric perspective):– Line Cameras (ADS 40)– Large format digital frame cameras (??)– Multi-head digital frame cameras (DMCTM, UltrCam,
DiMAC 2.0)– Medium-format Digital Cameras (MFDC):
• Mass-produced MFDC for mapping purposes (DSS, DiMAC Light)
• MFDC for mapping purposes from data providers (DAC 101)• Amateur medium format digital cameras (AMFDC)

MFDC from Data Providers
• DAC 101: Camera assembled by Selkirk Remote Sensing• The camera utilizes a 60mm Rollei lens with a Rodenstock Apo-Sironar shutter and a
22 megapixel digital back (5440x4080 Imacon Ixpress 132 Digital Back with 9µm pixel size)

MFDC: Relevant Questions
• Is the use of amateur MFDC in mapping applications a temporary or permanent phenomenon?
• How to develop meaningful standards for evaluating the outcome from the calibration procedure?
• How to develop meaningful standards for evaluating the stability of the involved camera?
• Is there a flexibility in choosing the stability analysis tool, which is commensurate with the geo-referencing procedure to be implemented for this camera?

• Regulating the use of imaging systems in mapping applications can be done through either:– Having a government body (third party) responsible for
the evaluation/calibration of the imaging systems.• Widely adopted for analog cameras (USGS, NRCAN).
– Certifying the imaging systems.• Suitable for digital imaging systems intended for mapping
