Kucera has been performing digital stereocompilation work in-house since the 1980s and currently compiles new and updated digital planimetric and terrain model/topographic data. The scales and contour intervals range from 1″=10′/0.5′ contours to 1″=2000′/20′ contours.
Kucera’s digital stereocompilation technology includes both first order analytical (Zeiss P2/P3) and the most advanced softcopy (Cardinal Systems VR2, Z/I Imaging SSK) mapping systems.
Kucera’s Zeiss P2/P3 analytical stereoplotters are used for various types of newly produced mapping, including high accuracy/large-scale work where maximum pointing accuracy is required, smaller projects having new digital image requirements, and mapping of complex terrain (e.g., urban areas, heavily vegetated, and rugged areas).
The softcopy stereoplotters allow newly compiled/created and/or existing vector map feature data to be viewed stereoscopically on top of the corresponding digital stereomodels of project aerial imagery, and provide a variety of automated and semi-automated compilation features which allow updating work to be performed more efficiently and with greater throughness and accuracy.
In performing DTM and planimetric feature update work, the softcopy system operators thoroughly scan each stereo-image of the designated update area, with the review and update being performed by groups of related layers to maximize thoroughness. DTM updates are accomplished by outlining/windowing areas of change (i.e., areas where existing DTM elements do not match the terrain) and replacing the existing DTM for these areas with newly compiled DTM.
Updates to planimetric feature mapping include addition, deletion, or revision of existing features to represent current conditions. The updates are made directly on the softcopy plotter as identified, with ties being made to surrounding unchanged data as needed to maintain seamless transition.
