Remote Sensing (GPR) Resources
This page is dedicated to informing communities and individuals about remote sensing and ground penetrating radar technologies, including their uses, limitations, and alternatives. We also provide resources on how to approach planning a remote sensing survey, as well as resources for training and open-source software for those who wish to build capacity and learn more about these technologies.
If you haven't already, it is recommended to review a few of the INTRODUCTORY GUIDES to understand the role of GPR or other remote sensing techniques in searching for unmarked burials of missing children and other important considerations for this work.
As a quick note, there are multiple ways to speak about certain types of information and definitions that are presented here. Below we quickly provide some high-level definitions of common terms to help provide some clarification as you view the different resources.
Remote Sensing - the scanning of the earth to obtain information about it often without making physical contact. There are multiple types of remote sensing technologies which can be broadly categorized into ground-based, airborne, and satellite techniques.
Near-Surface Geophysics - is a field of study that uses specific technologies and methods that focus on studying small-scale features in shallow areas of the Earth's subsurface.
Ground Penetrating Radar (GPR) - is a type of ground-based remote sensing technique used in near-surface geophysics that uses radar pulses to image the subsurface.
LiDAR - stands for Light Detection and Ranging. An airborne remote sensing technique that uses light in the form of a pulsed laser to explore the Earth's surface.
