Geodetic benchmarks are fixed physical markers with precisely known coordinates, used by surveyors for referencing measurements, calibrating equipment, and validating GNSS setups. In AZ, these control points are maintained by national mapping agencies and international networks such as EUREF, IGS, and NGS, plus OpenStreetMap contributions from local surveyors.

SurveyingPedia aggregates these public datasets into a single searchable map. Each point on this page is cross-referenced with its source agency, and linked to a detailed datasheet with satellite imagery, coordinates in multiple reference systems, and community verification status.

Data is refreshed daily via automated harvesters, and new points are added continuously. If you are a licensed surveyor in AZ and want to contribute your records or correct an existing entry, create a free account and join the community.
