Question 1

How can I convert my cemetery’s paper records into searchable digital records?

Accepted Answer

Sentry Mapping turns paper ledgers into a living, searchable database. We scan and key your records, confirm every burial with ground-penetrating radar, map each plot by GPS, then load everything into an online Geographic Information System (GIS) and cemetery-management software. Staff and visitors can now search names or lot numbers in seconds.

Converting box-loads of yellowing documents into a modern cemetery GIS is easier than you think. First, our team collects copies of your plot cards, ledgers, and old hand-drawn maps and scans them into high-resolution images. We transcribe key fields, such as name, dates, lot number, and owner, so nothing is lost.

Next, certified technicians walk every row with high-frequency ground-penetrating radar to detect marked and unmarked graves, while GPS and drone imagery fix each burial plot to sub-inch accuracy. These layers feed into a digital cemetery mapping database.

After quality checks, you receive: 1) a printed master map for the office, 2) a password-protected web map the public can search by name, and 3) two free years of Chronicle cemetery management software. Chronicle lets you update burials, attach deeds or photos, and print lot certificates without extra subscriptions. Because the system is cloud-based, your records are safe from fire, water, and employee turnover. The result is accurate burial plot mapping, easy grave locating, and peace of mind that you will never resell an occupied space.

Question 2

How can I locate unmarked graves in an old cemetery without disturbing the ground?

Accepted Answer

Use high-frequency ground-penetrating radar (GPR) to scan the cemetery surface, then overlay the subsurface reflections on a precise GPS/GIS map. This non-invasive method detects unmarked grave shafts, outlines each burial plot, and creates a digital record—so you find every grave without digging or disturbing the soil.

Ground-penetrating radar cemetery surveys are the gold standard for unmarked grave detection because they read what lies below the turf instead of moving it. During a Sentry Mapping cemetery survey, technicians roll a high-frequency GPR cart across each walkway and row.

The antenna sends radio waves about 12 ft deep; when the signal hits a disturbed soil column (the signature of a grave shaft) it bounces back, creating a hyperbola visible on screen. We record every reflection with survey-grade GPS, then feed that data into our cemetery GIS mapping workflow. Within days you receive a digital cemetery mapping file that pinpoints each burial plot—marked or not—overlaid on recent drone imagery. Because the process is contact-less and lightweight, there is zero damage to headstones, landscaping, or fragile historic soil layers.

Beyond the map, you get a printed master plan, a searchable web map, and two free years of Chronicle cemetery management software. Staff can click any plot to view burial details, upload documents, or confirm availability before selling a space. This combination of GPR grave locating and intuitive software eliminates guesswork, prevents accidental disturbance, and preserves heritage while maximizing usable ground, all without a single shovel hitting dirt.

Question 3

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 4

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.

Question 5

What is the difference between a “burial-plot map”, a “web-map”, and a “GIS survey”?

Accepted Answer

A burial-plot map is the precise, static master layout of every grave and available space, produced from a one-time GPR/GPS survey. A web-map is the online, clickable version of that map that staff and families can access online to search from any device. A GIS survey is the underlying field data-collection process that feeds both products.

Think of the three deliverables as steps in one streamlined cemetery-mapping workflow.

1) During the GIS survey, Sentry Mapping technicians walk every row with survey-grade GPS and ground-penetrating radar equipment. The instruments record x-y coordinates, depth readings, and attributes—marked and unmarked grave locations, utilities, pathways, trees—creating a rich spatial database. This is the foundation of professional cemetery GIS mapping and integrates seamlessly with municipal or county GIS systems.

2) We produce the burial-plot map from the GIS survey data. This is the authoritative, to-scale master plan you can print, frame, or keep on the grounds. Every lot line, section number, and interment is plotted in its exact position, so you instantly see which plots are occupied, reserved, or available for sale.

3) We then publish the same data as an interactive web-map so your staff, grounds crew, and even visitors can zoom, search a name, or tap a grave for details on a phone or tablet. The web-map lives in the cloud, receives free updates when new burials are added, and links directly to Chronicle’s cemetery management software for digital record-keeping.

Together, the GIS survey, burial-plot map, and web-map turn outdated paper charts into a living, searchable, digital cemetery mapping system that eliminates double-sold plots, speeds grave locating, and preserves your cemetery’s heritage for generations.
