What training or qualifications should a cemetery-mapping service have for GPR work?
A qualified cemetery-mapping service employs manufacturer-certified GPR technicians, FAA-licensed drone pilots, and GIS/GPS specialists who follow OSHA safety rules and carry full insurance. Sentry Mapping meets these standards, offering cemetery-only expertise, high-frequency ground-penetrating radar, sub-inch GPS, and turnkey maps for every marked or unmarked grave nationwide.
Ground-penetrating-radar cemetery surveys are only as reliable as the people behind the cart. Look for a provider whose staff have completed manufacturer training—e.g., GSSI or Sensors & Software operator courses—so they can tune high-frequency (400–900 MHz) antennas, filter noise and interpret hyperbolas correctly for accurate unmarked grave detection. Survey-grade RTK GPS skills are equally critical; sub-inch positioning drops every reflection into the right burial-plot polygon, feeding precise digital cemetery mapping and burial plot mapping.
A top-tier team pairs GPR certification with formal GIS competency and can deliver ESRI-compatible shapefiles or load results straight into cemetery management software. Because projects also blend drone photos with radar data, at least one crew member should hold an FAA Part 107 Remote Pilot certificate and understand photogrammetry. On-site work also calls for OSHA 10-hour (or higher) safety training.
Sentry Mapping meets every requirement. Our cemetery-only focus means each technician is factory-trained on world-class GPR, versed in heritage-preservation etiquette, and backed by precision GPS with drone imagery. The result is a printable master map plus a no-fee, interactive cemetery GIS web map that shows every marked or unmarked grave—giving you confidence to sell plots, plan future interments, and protect your cemetery’s legacy.
