Survey linework software for CAD and GIS handoff

Use SurveyMarkup to prepare and review coded linework before it goes to CAD or GIS. The Map Linework workspace can flag missing codes, geometry issues and CRS metadata inconsistencies, but it does not verify coordinate authority — every export stays a working file for review.

Synthetic sample geometry — no real client data needed.

Advisory only

Advisory and unverified — not for survey deliverables. A registered surveyor must confirm any output before it is relied on.

What SurveyMarkup can flag or organise

  • Missing or inconsistent feature codes
  • Geometry that looks worth a manual check
  • CRS metadata mismatches before export

What it cannot prove or certify

  • It does not verify coordinates are correct
  • It does not certify cadastral linework
  • It does not replace CAD/GIS drafting review

Draw and code survey geometry

Build or import linework, apply feature codes and keep the output structured for downstream drafting. The workspace is designed around the codes Australian crews already use.

  • Feature-coded points and lines
  • KERB, FENCE, TREE, EDGE and similar codes
  • Structured layers ready for review

Preview GDA2020, GDA94 and MGA metadata

See the coordinate reference selections that travel with the linework so mismatches can be caught before export. CRS handling is a preview and metadata-plausibility aid — coordinates remain unverified.

Check export readiness, then hand off

Run advisory checks before exporting CSV, DXF, GeoJSON or KML. The exports are reviewable handoff files, not survey deliverables.

Worked example · synthetic

Field-coded linework for a small subdivision is prepared for CAD handoff.

What SurveyMarkup surfaces

  • Two points with missing feature codes
  • A polygon that does not close
  • Project datum GDA2020 but one layer tagged GDA94 — a CRS mismatch to review

Reviewer's call: The surveyor corrects the codes and confirms the CRS before the DXF is used. The export stays an unverified working file.

Frequently asked questions

Can I export DXF?

Yes — Map Linework supports advisory CSV, DXF, GeoJSON and KML export. The files are working handoff files for review, not final deliverables.

Does it verify GDA2020 coordinates?

No. CRS handling is a preview and metadata-plausibility aid. Coordinates remain unverified and must be confirmed by a registered surveyor.

Is it a replacement for my CAD package?

No. It is a review and handoff aid that complements 12d, Civil 3D, QGIS and similar tools — it does not replace them.
