Drone Based Geophysical Surveys for Groundwater Applications

Presented on Tuesday, December 3, 2019

Drones have been used for photogrammetry and high resolution LIDAR surveys for several years.  Recently magnetometers have been deployed from drones.  This presentation will provide a general overview of drones and drone based mapping, but will focus on geophysical mapping with drone based systems.  Case histories will be presented that demonstrate drone based magnetic surveys to locate abandoned well casings and pipelines.  Two case histories will be presented demonstrating the use of drone based magnetometry to explore the Crestone Crater in Great Sand Dunes National Park to determine the structure and vertical extent of the feature, and an example where a drone based magnetometer survey was used to map basaltic bedrock for a reservoir siting study.  The presentation will provide an overview of several developing electromagnetic instruments that will allow electrical conductivity mapping in depth ranges of a few meters to several hundred meters.
