Besides the large format cameras based on film material and the multi-head
solutions with separate heads for the different colour channels there exist the need
for compact camera systems based on medium format. Latest developments regarding
resolution of CCD-Chips, adaptation on lenses solely for the digital imagery and
the demands of the survey market regarding the footprint as well as the progress in
digital post-processing and photogrammetric mapping caused reactions of the manufactures
of cameras to cope with the new demands. This article introduces the usage
of professional lenses adapted to digital backs and possibilities to produce a larger
surface area by using an interconnected camera system with up to eight single cameras.
This also allows the simultaneous use of RGB and Infrared in visible wavelengths
e.g. for forestry surveying. Together with the integration into LiDAR systems, mapping
and surveying especially in the growing demands of infrastructural analysis can
be performed fast and cost effective. This presentation describes some case studies
with regard to infrastructural projects within land use management and urban development.
