Question 1

How long does it take to map a municipal cemetery from survey to web‑map launch?

Accepted Answer

Sentry Mapping’s cemetery mapping service instantly turns ground-penetrating radar and high-precision GPS survey data into a clean, scalable cemetery map. Every grave—including unmarked burials—appears in its exact location, and plot boundaries are redrawn automatically, giving you an accurate master map plus an interactive online version within a few days to a few weeks depending on the size of your cemetery.

Professional cemetery mapping with Sentry Mapping replaces time-consuming hand redrawing with automated digital drafting. After technicians scan your grounds with high-frequency ground penetrating radar, they capture accurate GPS points for each marked and unmarked grave. Those coordinates flow directly into GIS software, where AutoCAD-style routines auto-draft fresh lot lines, walking paths, and section labels. The result is a to-scale cemetery plot map that matches reality—no guesswork, no erasure marks.

Need to update a burial record later? Edits made in Chronicle cemetery management software immediately appear on both maps, eliminating duplicate data entry. Municipal GIS officers can also import the shapefiles and attribute tables directly into ArcGIS or QGIS, keeping citywide records in sync. Because the entire drafting workflow is automated from the original survey data, you avoid costly drafting fees and gain a future-proof, digital foundation for perpetual care, plot auditing, and heritage preservation.

Question 2

What are best practices for preserving heritage in historic cemeteries with missing records?

Accepted Answer

Sentry Mapping's cemetery mapping with ground-penetrating radar and easy software is the safest way to safeguard heritage when paper burial records are lost. First locate every marked and unmarked grave, digitize old ledgers and photos, create a searchable plot map, then share it online for staff and families.

Digital cemetery mapping protects fragile history even when ledgers are missing. Start with a non-invasive ground-penetrating radar cemetery survey to reveal every burial, marked or unmarked, without disturbing soil. Sentry Mapping crews couple high-frequency GPR with precision GPS for dependable unmarked grave detection and burial-plot mapping accurate to the inch. Drone imagery and headstone photographs are synced to each coordinate so caretakers see exactly what sits above and below ground in the cemetery GIS mapping portal.

Next, scan any surviving deeds, notebooks, or obituaries and import them into a cemetery management software program. The system links every document to the right plot, and its grave-locating search returns results in seconds, ending guesswork. Add oral histories while elders are still available, and flag cultural or veteran markers so maintenance crews can protect them.

Finally, publish a public-facing web map through Sentry Mapping that can be periodically edited to stay current, reducing staff calls and accidental plot reuse so descendants can find relatives online. If you need full record-keeping capabilities, we also offer a complete cemetery management software program.

Schedule an annual walk-through to capture new interments and condition photos; the GIS map updates in minutes, keeping heritage data alive. By combining GPR detection, digitization, and open GIS sharing you create a living record that respects the past and guides every future decision.

Question 3

What are the advantages and disadvantages of using Ground Penetrating Radar?

Accepted Answer

Ground penetrating radar lets you see every burial without digging, saving time, money, and heritage. It is quick, non-destructive, and pairs with GPS to build precise digital cemetery maps. Downsides: clay or water-logged soils weaken the signal and careless reading can mislead, so its vital to hire trained experts like the technicians at Sentry Mapping.

Ground penetrating radar (GPR) is the core tool behind Sentry Mapping’s professional cemetery mapping service. Rolling a low-power antenna cart across the turf, the system sends radio pulses into the soil and records reflections from disturbed layers, vault fragments or voids—ideal for grave locating, unmarked grave detection and utility avoidance.

Key advantages include:

Non-invasive scanning that protects fragile monuments and heritage
High coverage—two technicians can scan several acres a day, turning decades of paper records into accurate digital cemetery mapping and a burial plot map tied to centimeter-level GPS
Immediate insights—real-time profiles show occupied versus open plots, supporting smart space planning and revenue protection.
Seamless integration—each radar hit flows straight into our cemetery management software, giving staff and visitors a searchable, web-based cemetery GIS map.

Disadvantages, and how Sentry Mapping manages them: heavy clay or saturated soils can weaken the signal, so surveys are timed for drier spells and antenna frequency adjusted; raw hyperbolas can mislead the untrained, so GPR-certified technicians cross-check results with GPS and drone imagery to ±6-inch accuracy; and standard 400–900 MHz antennas read best to about eight to ten feet—if a target sits deeper, alternate methods are recommended.

With the right expertise provided by Sentry Mapping’s experts, GPR delivers a fast, respectful and verifiable map of every marked and unmarked grave.

Question 4

What are the hidden risks if a cemetery does not properly map its plots?

Accepted Answer

Cemetery mapping errors trigger big bills: you might sell an occupied plot, pay to move remains, lose revenue to unsold space, and waste staff hours hunting paper records. Professional ground-penetrating-radar mapping prevents these hidden costs and protects your reputation.

Without reliable cemetery mapping, money slips away. An inaccurate burial plot map can lead your team to re-sell a plot that already contains an unmarked grave. Correcting that mistake usually means a disinterment plus new vault, labor, and re-interment. Families may sue for emotional distress, adding legal fees and public embarrassment.

Fear of striking unknown burials forces crews to dig wider or avoid usable ground, leaving prime space unsold. Even ten “ghost” spaces equal tens of thousands in lost revenue. Staff also spend hours hunting ledgers for each request. Combined, all of these avoidable expenses easily exceed the cost of a professional survey.

Sentry Mapping removes those risks. Our ground penetrating radar cemetery survey detects every marked and unmarked grave, utility line, and obstacle. We deliver precise GPS burial plot mapping and targeted grave locating. You also receive a printed master map plus a searchable digital cemetery GIS map hosted free online. We include a read-only program that lets visitors walk straight to the grave on a phone, and it can be converted to a full cemetery management software program at most any time to keep your digitized cemetery records current. Professional cemetery mapping turns hidden costs into clear data so you can protect heritage, avoid liability, and unlock revenue.

Question 5

What is cemetery mapping?

Accepted Answer

Cemetery mapping is the process of creating an accurate, searchable map of every grave and plot in a cemetery, including unmarked burials. Using tools like GPS, GIS, aerial imagery, and ground penetrating radar, Sentry Mapping documents exact locations so you can protect graves, avoid double-sold plots, and guide visitors quickly.

Cemetery mapping is the process of documenting where every burial and plot sits, then turning that into a map your staff and visitors can search. Done right, it combines surface features like rows, roads, and sections with what is below ground.

Sentry Mapping provides professional cemetery mapping across the 48 contiguous United States using survey-grade GPS, cemetery GIS mapping, drone or aerial imagery, and ground penetrating radar cemetery scans for unmarked grave detection. Depending on your needs, that may include:

– Burial Plot Mapping to mark each gravesite and redraw plot lines

– Grave Locating for a specific missing or unmarked burial

– Cemetery Survey and Drafting to build an accurate as-built map even when paper records are wrong or missing

– Web Maps for Cemeteries that are clickable and searchable with no annual fee

Your deliverables typically include a printed master map plus a digital cemetery map you can open online to search names, view plot details, and see where space is sold, reserved, or available. For ongoing record work, Sentry also offers Cemetery Management Software with Chronicle, with two years of free Chronicle Viewer access when you partner, so you can keep the map and records current over time.
