Expert Cemetery GPR Mapping Services

Our cemetery mapping services help identify each burial site and mark the location with our innovative mapping system and design.

Careful care should be taken with locating unmarked graves and identifying each burial to ensure history is preserved. Unfortunately, due to damaged, lost, or inaccurate cemetery records, many graveyards no longer have access to detailed information regarding the exact layout of their burial plots or those that are resting in the cemetery.

Enjoy a visually appealing, verified for quality and accuracy, the map that can be displayed for visitors for decades to come. Not only will you receive a hard copy for historic preservation, but you will receive an electronic copy that can be added to your website for the community to explore from their homes.

How Does GPR Work to Map Cemeteries?

Our highly trained field technicians complete a scan of each square foot of the area to be mapped. As the real-time Ground Penetrating Radar (GPR)  data appears they will mark the detected graves. 

This data can be difficult to read without the proper training. When the signal reflects off a marked or unmarked grave the GPR’s display shows a hyperbola or conical curve shape.

Understanding Your Cemetery’s GPR Profile

Ground Penetrating Radar (GPR) allows us a glimpse into the subsurface makeup of your cemetery’s land, and the layout of the graves located there. Your cemetery’s GPS and GPR profile allows you to make informed choices for future planning while offering better service to the patrons visiting their loved ones. 

Cemetery Mapping with Ground Penetrating Radar (GPR) detection is the least destructive geophysical testing method available today meaning no grave will be left disturbed.

Graves that are 50 years old or more produce less distinct hyperbola and are difficult to detect compared to newer graves that are much easier to locate.

Cemetery Mapping with GPR

Often, when cemeteries are initially plotted, small parcels of land are sectioned off into lots. These lots are sized and allow for a specific number of graves. As land prices rise and space becomes scarce, it becomes imperative for real estate to be used efficiently and allow for as much revenue to be made as possible.

Ground Penetrating Radar (GPR) scans with Sentry Mapping allow cemetery managers to adjust and ensure the land is used in the most economical way possible.

Case Study

Preserving heritage at a 150-year-old cemetery.

Problem:

A 150+ year-old historic cemetery faced a significant challenge: it had no records or maps of its burial sites. This lack of documentation left the caretakers unsure about the availability of space for new burials, raising concerns about the preservation of the cemetery’s heritage and the respect due to those interred.

Solution:

Sentry Mapping Services stepped in with a comprehensive approach to solve the cemetery’s challenges. Utilizing advanced Ground Penetrating Radar (GPR) technology, the team meticulously scanned the entire area to locate unmarked graves. This thorough investigation was followed by the creation of a detailed map that not only marked every known burial but also included names, birth and death dates, creating a rich tapestry of the cemetery’s history. To complement this, Sentry Mapping provided a clickable and searchable web map, making navigation and management effortless for the caretakers—all at no additional cost.

Result:

Thanks to Sentry Mapping’s expertise, the cemetery now has a clear understanding of its layout and capacity for future burials. This newfound knowledge ensures that every inch of sacred ground is used respectfully and efficiently, honoring the memory of those at rest. Moreover, the digital tools provided have secured the cemetery’s heritage for future generations, making it easier for families and historians to connect with their past. The once uncertain terrain of the cemetery is now a carefully mapped and cherished space, its legacy preserved and its management streamlined.

Common Questions

Are GPR cemetery surveys safe for areas with fragile historic headstones?

Quick Answer

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.

Can ground‑penetrating radar still detect graves that are over 100 years old?

Quick Answer

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.

Hear From Our Satisfied Clients

Sentry Mapping surveyed and mapped three cemeteries in our small community. It was amazing how many unknown graves were found, many dating as far back as the 1800s. The older cemeteries had rocks and pieces of wood for grave markers that had been moved or lost over the years. With the help of Sentry Mapping our community was able to put a permanent marker where each grave was located. We were very pleased with Sentry Mapping. They did a fantastic job and I would recommend them to anyone who needs this service.

We hired Sentry Mapping to locate my great-grandfather’s grave which was without a marker for more than 100 years. Due to a lack of cemetery documentation, our new memorial was placed in his guardian family’s plot; however, we could not rest until we were sure we had found his actual resting place. Sentry Mapping located Fred and the cemetery now recognizes his burial in their documents. It is a huge relief to know we got it right! His life needed this celebration, and we needed the peace of closure. Thank you so much, Benton, we truly appreciate all that you did for our family!

I couldn’t be happier with my experience working with Sentry Mapping for remapping our cemetery! They made the whole process so painless and easy- Benton was so easy to communicate with and was a HUGE help in cleaning up a giant mess. Thank you so much for your services!
