Coded linework QA checks explained with a synthetic example
Map Linework runs advisory data-quality checks on coded linework — MGA zone plausibility, CRS/datum presence, missing codes, duplicate points and zero-length geometry. Coordinates remain unverified.
Advisory and unverified — not for survey deliverables. A registered surveyor must confirm any output before it is relied on.
Missing or inconsistent codes
Features without expected codes or with near-duplicate code names are flagged for reviewer attention.
- BLDG vs BLDGF typos
- Empty code fields
- Unexpected code registers
Geometry quality prompts
Duplicate points, zero-length segments and closure hints are surfaced as advisory findings — not automatic rejections.
CRS and datum metadata
Declared GDA2020, MGA zone and AUSGeoid references are checked for presence and plausibility only.
