Ground penetrating radar (GPR) is an easy to use, non-invasive technique used to map contacts between materials with different properties (i.e., density, electrical conductivity and dielectric permittivity). Common terrain applications include mapping stratigraphic contacts, ice thickness, peat thickness and lake and river bottom substrate. We have also used this tool to detect and map unmarked grave sites in cemetery projects, buried object detection, and for mapping buried pipelines and other infrastructure within a specific study area. Our GPR capability includes both field surveys and post-survey (desktop) processing using specialized GPR processing software. JDMA currently owns a Noggin 250MHz GPR system which can be configured for use as either vehicle / ATV towed (for larger study areas) or in a modular smart-cart system (for small, detailed studies). Additional antenna frequencies (100MHz to 1000MHz) can be rented and integrated into JDMA’s GPR system if necessary.
