摘要：With the introduction of the new aerial digital mapping cameras, the operational aspects for aerial photo flight projects will change. New task, like digital image data handling and data copy in the filed will be implemented into the workflow. Instead of a film, digital data will be shipped and archived. The camera operators and the crew have to get familiar with the new work steps. The Z/I Imaging DMC Digital Mapping Camera System is used as an example to explain the operational procedures and the data workflow. To set up a proper mission planning the required GSD ground sampling distance has to be determined. Referring to the traditional film camera, this is a combination of photo scale and scanning resolution. After a photo flight mission the digital film has to be developed. The airborne mass storage device with the raw image data will be removed from the aircraft to the office, where the image data post processing will take place. If the crew is away from the home base on an outbound mission and has no access to the post processing workstation, the image data will be copied from the airborne mass storage device to a different media, like removable hard disk drives or tapes. The handling of this process has to be full automatic to reduce time and costs and to reduce the stress for the crew. To get the camera ready for the next mission as quickly as possible is an important factor. The data copy can either be done in the aircraft or in the hangar or hotel room. The digital cameras are offering new possibilities for on-site quality checks. A first image data quality evaluation can be done in the air during the mission. Especially for areas with air space restrictions this will be a big time and cost saver.
