How to Map a Cemetery Without a GPS Survey
Cemetery GPS and GPR surveys cost $5,000–$25,000+. For most cemeteries you don't need one. Here's how to build a working digital cemetery map in a single afternoon, for $0, using just a satellite image or a scanned paper map.
You can map a cemetery without a GPS survey in a single afternoon using cemetery software like CemeteryBase (included in the $99/month subscription). Two approaches: (1) use Mapbox satellite imagery as the base layer and trace plots from above; (2) scan and upload your existing paper cemetery map as a visual overlay. Most cemeteries use a hybrid — satellite for accuracy, paper map for section labels and historic plot numbering. Self-serve mapping gets you 1–3 foot accuracy — enough for family navigation, deed generation, and online plot sales. Commission a GPS or GPR survey only if you need sub-inch accuracy, unmarked-grave detection, or legal-grade documentation.
Self-serve vs GPS survey, by dimension
When self-serve is enough and when the GPS survey is worth $5,000+:
Three approaches to self-serve mapping
Satellite imagery base layer
Best for: Modern cemeteries with visible headstones from satellite
Mapbox satellite imagery is recent (updated every 1–3 years for most US cemeteries) and shows headstones clearly at high zoom. Best for cemeteries from the last 50 years with maintained stones.
Pros
- Always current
- No paper map needed
- Free aerial reference
Cons
- Cloud cover or tree canopy can obscure plots
- Historic flat markers may not show
Paper map upload as overlay
Best for: Historic cemeteries with detailed paper records
Scan your existing paper cemetery map (any quality from clean printed PDF to faded hand-drawn document) and upload it. CemeteryBase displays it as a translucent overlay you can trace plots against.
Pros
- Captures historic plot numbering exactly
- Shows informal section labels
- Useful when satellite imagery is poor
Cons
- Need to scan/upload paper first
- Lower coordinate accuracy than satellite
Hybrid (paper + satellite)
Best for: Most real-world cemeteries
Use satellite as the foundation and paper map overlay for section labels and historic plot numbering. Toggle between the two as you draw.
Pros
- Best of both
- Reduces errors
Cons
- Two assets to manage
Step-by-step self-serve mapping
Pick your base layer
Two options: (A) Scan your existing paper map and upload it as a visual overlay; (B) Use Mapbox satellite imagery centered on your cemetery's address. Satellite is usually easier and more accurate for modern cemeteries; paper map overlay is better for historic cemeteries where the paper has section labels and informal notes.
Center and zoom
Type your cemetery address into the map search. Zoom in until individual headstones or rows are visible. Save the view as your default zoom level.
Create your sections
Name each section (e.g., Garden of Peace, Section A, Veterans Row, Old Pioneer). Optionally draw the section boundary polygon directly on the map by clicking corner points.
Use the grid tool for regular sections
For sections laid out in regular rows and columns: select the section, click "New Grid," set the row/column count and plot spacing (typically 4 feet wide x 8 feet deep for adult plots). The tool generates dozens or hundreds of plots in one click.
Adjust individual plots
After the grid is generated, you can drag individual plots to align with visible headstones in the satellite imagery. Most cemeteries spend more time on this step than on the initial grid generation.
Handle irregular sections manually
For sections with no regular grid (historic, family plots, mausoleum), click on the map to place individual plots one at a time. Slower, but flexible.
Link plots to burial records
Import your burial records via CSV. CemeteryBase auto-matches by plot identifier. If your records use plot IDs like "A-12" but the map plots are unnumbered, you'll do a one-time numbering pass.
Review and publish
Walk through the map zoom by zoom. Compare against your physical cemetery. Fix any misalignments. When satisfied, publish the public page so families can search.
When the GPS survey is actually worth it
- You have many suspected unmarked graves and need ground-penetrating radar to find them
- You need sub-inch accuracy for state or county legal-documentation requirements
- The cemetery is large (10+ acres) with irregular layouts and historic plots
- You're a non-profit cemetery and donors fund the survey as a heritage-preservation grant
- You want a one-time survey + then keep CemeteryBase as the working digital system

Frequently asked
Do I need a GPS survey to digitize my cemetery map?+
No. Most cemeteries digitize their map self-serve using either a scanned paper map as a visual overlay or Mapbox satellite imagery centered on the cemetery's address. The visual grid tool generates hundreds of plots per click. A GPS survey gives you sub-inch accuracy and finds unmarked graves, but is not required for a functional digital map.
How much does it cost to map a cemetery without a GPS survey?+
$0 with CemeteryBase self-serve — included in the standard $99/month subscription. A professional GPS or GPR survey from Sentry Mapping or CIMS costs $5,000–$25,000+ depending on cemetery size and survey type. For most cemeteries the self-serve approach is sufficient.
When should I commission a GPS survey instead of self-serve?+
Three cases: (1) you have many suspected unmarked graves (ground-penetrating radar is the only way to find them); (2) you need sub-inch accuracy for legal or regulatory reasons; (3) the cemetery is large (10+ acres) with irregular plot layouts where the grid tool would struggle. For typical churchyard or municipal cemeteries with marked graves, self-serve is fine.
How accurate is self-serve cemetery mapping vs a GPS survey?+
Self-serve mapping using satellite imagery is accurate to about 1–3 feet — enough to identify the right plot when a family visits. GPS surveys are accurate to under 1 inch. For navigation and visualization purposes the difference doesn't matter; for unmarked-grave detection or legal-grade documentation, GPS is required.
Can I upgrade from self-serve to a GPS survey later?+
Yes. If you later commission a GPS or GPR survey, the resulting CSV with lat/lng, KML, KMZ, or shapefile can be imported and will replace or supplement your existing plot data. Burial records linked to plots are preserved through the import.
What if my cemetery has irregular plot layouts?+
The grid tool handles regular rows; for irregular sections (historic, family plots, mausoleum walls), draw individual plots manually by clicking on the map. Slower than the grid, but flexible. Some cemeteries use a combination: grid for the modern sections, manual placement for the historic ones.
How long does self-serve mapping actually take in practice?+
For a typical 1,000–3,000 plot cemetery: 1–3 hours total — about 60 minutes for sections and grid generation, 30–90 minutes for individual plot adjustments, and the rest for record linking and review. Cemeteries with 5,000+ plots can take a full afternoon.
