How It Works

Three steps from checkpoint CSV to a defensible, branded PDF.

STEP 1

Upload

Upload your checkpoint CSV with surveyed truth and model coordinates.

STEP 2

Compute

RMSE, CE90/LE90, accuracy class, and the correct Tested/Produced statement.

STEP 3

Two-Sided

Operators generate reports. Buyers verify deliverables. Both get defensible accuracy.

For buyers

Accepting a Drone Survey Deliverable?

If you're a utility, DOT, or construction GC receiving a mapping deliverable, you should demand a defensible accuracy report. Upload the vendor's checkpoints and verify their accuracy claim independently — for free.

How Does Your Accuracy Compare?

Opt in to the anonymized accuracy benchmark and see how your positional accuracy ranks against peers in your vertical. No raw coordinates stored — aggregate only.

AccuracySuite provides advisory computations aligned to ASPRS Positional Accuracy Standards, Edition 2. It is not a certification, not a licensed land survey, and not a substitute for a surveyor's stamp. Results reflect only the data you supply. The operator/surveyor retains professional responsibility.
