AI agent for land surveyors

Datum and Coordinate System Check Agent

Every delivered file uses the required datum, coordinate system and units, with proof from check points.

Datum and Coordinate System Check Agent: what goes in, what the agent does and what you get

What it does

A survey is delivered in state plane feet and the engineer reads it as meters, or a vertical datum differs by 0.7 ft. This agent checks before delivery. It reads the project requirements and compares them with the datasets' stated coordinate systems, units and datums. It tests conversions on check points, such as a known benchmark, and flags mismatches. When a conversion fails the test, it fixes the setting and reruns. It repeats after any change. You approve the delivery package. Edge case: a file with missing projection metadata is held back and the agent infers a candidate from the coordinate range, to be confirmed by you.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

Read the steps as a list
  1. Delivery package assembled
  2. Read project requirements and file metadata
  3. Compare stated systems, units and datums
  4. Do all files state the required system and units?If not: Flag files with missing or wrong metadata and propose the setting. Back to step 2.
  5. Convert check points to the required system
  6. Compare results with known values
  7. Are all residuals within tolerance?If not: Correct the conversion setting and rerun. Back to step 5.
  8. Write the system statement for the delivery
  9. Surveyor approves the delivery packageThe agent waits here for your OK.
  10. Datum check record

How it decides

A file passes when its stated system matches the requirement and a conversion test on the check points agrees within tolerance.

  • Use the system named in the contract
  • Require tolerance on check points of 0.02 ft
  • Hold files missing metadata
  • Include a statement of units and geoid model

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Required system and datum
  • Tolerance (default 0.02 ft)
  • Check points
  • Delivery file types

What keeps you in control

It always asks you first

  • Surveyor approves the delivery package

Hard limits

  • Never deliver files itself
  • Never guess a system without confirmation

It stops when

  • Done: all files pass and package approved
  • Stop: requirement unclear

An example run

What happensFor a utility project in State Plane NAD83 feet, the agent found a CAD file with no metadata and a point file in meters. It converted both and tested on 3 benchmarks. One vertical value was 0.72 ft off because of the wrong geoid model, so it reran with the correct one and passed. The surveyor approved the package.
