Sample Description
Ground Penetrating Radar (GPR) is extremely effective at locating subsurface utilities and other materials, however, it does have certain limitations. Ground and soil conditions, weather, and the type of material being located are just a few of the potential limiting factors. In the event that conditions are not suitable for GPR scanning, an alternative recommendation can be made.
Yes, our mapping services not only identify existing graves but also clearly show which areas of your cemetery are available for new burials. With our detailed maps, you can easily plan for future burials, maximizing the use of your space while respecting the resting places of others. This makes it much simpler to manage your cemetery’s capacity and plan ahead.
Contact Sentry Mapping by phone or through our website and a representative will be in touch with you as quickly as possible. Our representatives can help you to figure out how GPR services can meet your needs.
GPR is extremely accurate! While accuracy is reliant upon various external factors such as ground and soil conditions, Sentry Mapping’s standards ensure that we are able to obtain the best results possible in each situation. Through past experience, when using a utility locating antenna for scanning, the accuracy is +/- 6 inches to the center of the object being located and +/- 10% to the actual depth.
Yes, you can. Our services provide you with a digital, searchable map of your cemetery, making it straightforward to track and locate specific burial plots. Whether you’re looking for a particular individual or need to show visitors to their loved one’s site, our maps make the process quick and stress-free. This digital tool is designed to be user-friendly, ensuring anyone can navigate it with ease, which greatly simplifies the management and visitation of your cemetery.
Yes. GPR cemetery surveys are completely non-invasive: the radar cart rolls across the turf without touching monuments, and the radio waves are lower power than a cell-phone call. Sentry Mapping’s process leaves the soil, turf, and even the most fragile 1800s marble or sandstone headstones untouched.

Yes. High-frequency ground-penetrating radar can still pick up century-old graves in most soils because disturbed soil layers, vault remnants, or voids remain detectable. While resolution fades as coffins decay, Sentry Mapping’s specialized GPR and GIS workflow regularly finds 19th-century burials and older, as long as site conditions (soil, depth, moisture) are reasonable.

Sentry Mapping uses non-invasive high-frequency Ground Penetrating Radar (GPR) to scan every square foot of the site. This allows us to detect soil disturbances that mark burials, GPS-tag each hit, then publish the results on an interactive GIS cemetery map. The entire survey is completed without any form of excavation, preserving the historic grounds.
