CEMETERY MAPPING WITH GSSI GROUND PENETRATING RADAR SYSTEMS

Non-destructive GPR surveys are critical components of field investigations. Archaeologists commonly use GPR to locate, investigate, and protect/avoid cultural resources. This includes mapping unmarked graves and site assessments prior to construction activities.

Archaeologists and forensic specialists rely on GSSI ground penetrating radar (GPR) as a key tool for non-invasive investigations, whether the goal is landscape-scale site mapping, excavation planning, or locating forensic targets or sensitive cultural resources. GSSI’s remote sensing technologies have augmented the traditional archaeological and forensic toolkits for almost 50 years.

CEMETERY MAPPING

In cemeteries across the United States, there are the “forgotten” burials of unmarked and lost graves. This is usually a byproduct of fallen and/or relocated grave markers, though in some cases there may never have been a stone or other marker. Unmarked graves are also common to historical landscapes, battlefields, and crime scenes. Geophysical techniques, such as GPR, are needed to non-destructively locate these burials in cemeteries and in other locations.

Cemetery surveyors typically look for grave shafts that are vertical stratigraphic cuts, hyperbolic targets suggestive of coffins or vaults, and geometrical patterning in 3D time slices. Your challenge is to explore the subsurface without disturbing the burials. Every cemetery is different, and local environmental and soil conditions can complicate the investigation.

  • UTILITYSCAN COMPACT GPR SYSTEM

    UtilityScan is a cost effective GPR solution ideal for archaeological, cemetery, and forensic work. The system provides excellent resolution, unparalleled data quality, and enhanced depth penetration. UtilityScan incorporates our patented HyperStacking technology which provides better data in less-than-ideal soil conditions and exceptional resistance to external noise.

    During field projects, lots of gear means that space is always at a premium. UtilityScan weighs just 34 pounds and can collapse to fit in the back of a small vehicle or even in an airline overhead compartment. The system’s small footprint is also beneficial during surveys – smaller size means better access to tight spaces or getting closer to walls, trees, or grave markers.

  • SIR 4000 RUGGED, HIGH-PERFORMANCE GPR CONTROLLER

    The SIR® 4000 is GSSI’s professional-grade, rugged (IP65) control unit and it is designed to interface with digital and analog antennas. The SIR 4000 works seamlessly with nearly every GSSI antenna, meaning you could survey cemeteries today, and tomorrow perform deep testing evaluations on a floodplain.

    As field scientists, we can rarely choose our site locations. To acquire the best data possible we need reliable, powerful, and user-friendly GPR equipment. The SIR 4000 incorporates advanced display methods and filtering capabilities for in-the-field processing. These include an intuitive Manual Gain process (for optimizing data display) and on-screen linear gain, high-and-low pass frequency filtering, and background removal. The SIR 4000 includes a real-time hyperbolic matching feature so you can quickly and accurately calculate soil dielectric in the field.
