SECTION MEETING
Baltimore MD – Washington DC – Harrisburg PA

TOPIC: Using Digital Photogrammetry for Rock Slope Mapping and Characterization

ABSTRACT:
New applications of photogrammetry have emerged with the advent of digital cameras, high-speed computers, and software capable of capturing and processing digital images and vast amounts of point cloud data. One such application is the mapping and characterization of rock slopes, which offers several advantages: 1) data can be collected safely from challenging to reach areas; 2) exposure to traffic and rockfalls is reduced; 3) a robust set of measurements can be collected quickly; 4) photogrammetry provides coordinates of each measurement; 5) discontinuities with limited exposure or having shallow dips can be measured by digitizing their trace; and 6) human error in recording the measurements is reduced. Although photogrammetry is useful for quickly and safely mapping rock surfaces and measuring discontinuity orientations, additional field reconnaissance may be necessary to collect other data depending on project requirements. Field reconnaissance is also necessary for validating the image model and mapping areas obscured by occlusion, vegetation, or other features. This presentation will cover the process of using terrestrial digital photogrammetry for rock slope mapping and illustrate how it was applied to the proposed conversion of a diabase quarry to a water supply reservoir in Virginia and highway rockfall mitigation projects in Pennsylvania.
PRESENTER:
Bill Roman works out of the headquarters of Gannett Fleming, Inc., in Camp Hill, Pennsylvania, where he is Chief Geologist in the geotechnical section of the company’s earth sciences and hydraulics practice. He earned a Bachelor’s degree at Beloit College in Beloit, Wisconsin, majoring in Geology and French. During his 31-year career with Gannett Fleming, he has used both majors, having begun his career as a marketing rep in Gannett Fleming’s international department and having worked on a variety of geotechnical projects in the realms of transportation, water supply, and environmental engineering since joining the firm’s geotechnical section in 1988. Bill is a registered Professional Geologist in Wisconsin, Pennsylvania, and Tennessee and a past president of the Harrisburg Area Geological Society.
