Review coded linework with advisory checks
Advisory data-quality checks on coded geometry — MGA zone, CRS/datum, missing codes, duplicate/zero-length geometry, closure, GNSS. Exports are advisory review files.
- FAILOpen polygon S2 — blocks export (data integrity)
- WARNDuplicate point near id 2
- REFGDA2020 / MGA zone 56
- CHECKMissing feature code on point 4
Advisory only · registered surveyor confirmation required
Use a synthetic sample first.
Coded linework picks up missing codes, duplicates and open polygons. SurveyMarkup runs advisory data-quality checks and an export-readiness checklist.

What it surfaces.
Quick questions.
Is this a survey deliverable?
No. Every result is advisory and unverified, and not for survey deliverables. A registered Australian surveyor must confirm anything before use.
What data should I use during the public beta?
Please do not upload or paste confidential client data. Use the synthetic sample files or your own cleared test files.
Does it change my original files?
No — source data is unchanged. Outputs are separate advisory review files.
Safety & scope
SurveyMarkup does not certify survey accuracy, cadastral compliance, legal boundaries, or coordinate correctness. It helps prepare and review working information, but original data and final outputs must be checked by a qualified user before use.
Assistance only - professional review remains required.
Please do not upload or paste confidential client data during public beta. Use synthetic or cleared test files.
