Digital Mapping Camera Replaces Film


The Cartographic Institute of Catalonia (ICC; Barcelona, Spain) is in the process of replacing film-based technology for transition to a fully digital workflow.

The Institute has purchased an Intergraph Mapping and Geospatial Solutions (Madison, AL) Z/I Imaging Digital Mapping Camera (DMC). The DMC is a large-format digital aerial camera system that will enable the ICC, which is the official mapping and geological agency of the Catalonian government, to complete the transition of its entire photogrammetric production processes to a fully digital workflow. The elimination of film-based data acquisition processes will enable ICC to dismantle its photo lab, thus gaining facility space as well as cut the time it took for film processing and scanning, thereby shortening total production time for orthophoto and map generation.

ICC required a data acquisition solution that could deliver quality aerial imagery from photoflights in non-optimal conditions and that could deliver multiple products such as black and white, color and infrared imagery in a single flight. Additional needs were for the imagery to be compatible for use with ICC's digital photogrammetric systems and workflows, specifically orthophoto and automatic aerial triangulation processes.

ICC selected the DMC after tests validated the camera met the agency's technical criteria of image quality, versatility and compatibility. Test flights flown over various types of terrain with resolution targets on the ground confirmed the imagery captured by the DMC was higher quality than traditional film-based systems.

"We are happy to put the final step in place to convert our entire process to a digital environment," says Josep Lluis Colomer, vice director, Cartographic Institute of Catalonia. "We will not only benefit from the time saved by having a completely digital workflow, but also from the highly precise imagery collected with the DMC."
