GEOLOGICAL PHOTOGRAMMETRY LABORATORY Technique

The Plotter Lab was established in 1971 for use by the Geologic Division personnel in photogrammetric compilation of geologic map data from aerial photography. While this fundamental goal has remained unchanged, the scope of photogrammetric developments supported through cooperative agreements with commercial and academic institutions has expanded the lab's role to include all aspects of Geologic Photogrammetry including aerial, terrestrial and close-range applications in fields of geologic mapping, volcano hazards, landslide monitoring, earthquake hazards, erosional geomorphology, glacial deformation studies, paleoseismology, underground fracture studies, nuclear wast disposal and weapons testing. All aspects of three-dimensional coordinate data acquisition from photographic base materials is currently addressed by the lab. GIS Integration: The Plotter Lab provides high-resolution 3-D coordinate data acquisition for subsequent export to GIS systems. We rely heavily on commercial 3-D cad software from which data can easily be migrated to any number of customer-supported GIS systems.
