The purpose of the Harrisburg Area Geological Society (HAGS) is to stimulate geologic thought, advance and disseminate geologic knowledge, and provide fellowship amongst area individuals interested in earth sciences. Monthly meetings present a realm of geologic topics, ranging from tectonics, coal, carbonate groundwater geochemistry, geomorphology, engineering geophysics, and ore mineralogy. Field trips allow members to visit geologic sites within and beyond Pennsylvania. All events are open to the public and free unless otherwise stated.
Meetings are held in person and on Teams at 6:30 PM on the second Thursday of the month, except summer months. Before the meeting a reception is held at 4:30 PM. Please email the HAGS secretary to be added to the email list and with any questions.
Benefits of a Budget-Conscious Drone Program
Presented by: Craig Ebersole, P.G. - PA Geological Survey
Meeting Date: November 10, 2022

Presentation Summary: Drone technology is more accessible than ever before and has numerous geologic applications. Recognizing the importance of this new technology, The Pennsylvania Geological Survey began its drone program in 2019. From its inception, the Survey’s drone program has been steadily expanding its capabilities with a budget-conscious approach. This talk is designed for those interested in implementing a drone program. In addition to examining the Survey’s drone equipment, software, and methods, this presentation will also review improvements to field safety and efficiency. Examples of high-resolution aerial imagery will illustrate applications ranging from use in publications to photogrammetry.
Speaker Bio: Craig Ebersole graduated from Juniata College in 2009 with a B.S. in Geology and later obtained a GIS certificate from Penn State. He is a Senior Geoscientist in the Pennsylvania Geological Survey’s Geologic and Geographic Information Services Division in Middletown, PA. Prior to joining the Survey, Craig worked in private industry on environmental cleanup and GIS projects and in the PA Department of Environmental Protection’s Safe Drinking Water program. His workplace passions include data management, making maps look their best, learning new GIS techniques, and philosophizing with colleagues about communicating science.
