- The Plotter Lab currently resides on the first floor of Bldg
25, Denver Federal Center, and occupies approximately 2500 ft2
immediately below the Geologic Division GIS facility.
- Analog Kern PG-2 optical stereocompilation instruments-currently
four PG-2 stereocompilation instruments are configured for rectified
analog transfer of data from aerial photographs to stable- or
paper-base map materials. Although this technology has been with
the Geologic Division for 25 years, it remains a heavily used
component of the geologic mapping component of Plotter Lab services.
- Digitally encoded Kern PG-2 stereocompilation instruments-two
PG-2 stereocompilation instruments are configured for digital
compilation of 3-D coordinate map data from aerial photography
using commercial stereocompilation software (Zeiss Cadmap/Bently
Microstation). This configuration eliminates the necessity for
subsequent digitizing or scanning of 2-D map data and enables
3-D data collection for modeling studies.
- Analytical Zeiss/Kern DSR-11 stereocompilation instrument-one
Kern DSR-11 analytical stereoplotter accomodates all project
requirements for non-conventional photogrammetric compilations
including aerial and hand-held, vertical and oblique photography,
multi-model stereo-strip aerotriangulations, automated DEM collection
and repeat deformation photogrammetric applications with automated
deformation vector determination. Currently this is the only
facility in the United States, and one of two in the world, with
the ability to orient and rectify multi-model strips of hand-held
photographs for use with analytical stereocompilation instrumentation.
A twin-sister of this analytical facility resides in our photogrammetry
collaborator's laboratory at the Technical Institute of Denmark.
- Soft-copy Photogrammetry-Recently cquired Zeiss Phodis
AT software installed on Silicon raphics hardware enables full
digital stereo image rectification with 3-D vector superimposition
for use in mapping, custom DEM, orthophoto and vector base material
production. Utilization of high-resolution digital imagery (7
micron scan resolution) integrates 3-D model studies with remote
data acquisition and seamless GIS integration. Currently available
for use only with aerial photography with upgrades to satellite
image capability in FY98.
