Point File Validator
Explore advisory duplicate-id, coincident-coordinate, easting/northing-order and zone-extent checks with a bundled fictional CSV point file.
Free advisory field tool — every result is computed in your browser from the inputs you provide and is advisory and unverified, not for survey deliverables. Where a published guideline applies, results only ever read “within guideline” or “exceeds guideline — review”. The full working is shown for every calculation so each step can be re-checked. Registered surveyor confirmation required before reliance.
Real-file selection is disabled during the synthetic public beta.
Load the built-in fictional point file below. No customer data is required.
Starter list only — replace it with your firm’s code table (comma, space or newline separated). Leave it empty to skip the code check. The list stays in this tab like everything else here.
What the checks look for
- PARSE
- the row could not be read as id,E,N[,RL[,code]]
- DUP-ID
- the same point id appears more than once in the file
- EN-ORDER
- the values look like northing,easting order — column order may be swapped
- E-RANGE
- the easting sits outside the theoretical MGA zone extent — units or zone may be off
- N-RANGE
- the northing sits outside the expected Australian MGA range — units or zone may be off
- COINCIDENT
- two different ids sit within the module's coincidence tolerance (stated in the finding message) — possibly a duplicate shot or a renamed point
- RL
- the third column is not numeric — the RL may be missing or the columns shifted
- CODE
- the point's code is not in the code list you supplied
This public-beta demonstration uses bundled fictional rows inside this browser tab. No customer file, file name, coordinate or project value enters analytics. Findings are advisory prompts to look again at specific rows; every professional decision remains with the registered surveyor.
Advisory output — confirm independently before reliance.
Safety & scope
SurveyMarkup helps prepare and review working information. Every professional decision remains with the registered surveyor, and original data and final outputs require qualified review.
Assistance only - professional review remains required.
