CRS Job Setup Checklist

Checklist
Set up the coordinate reference system for a job correctly before you collect or process data — datum, projection, zone, heights and transformations.
Still outstanding
- Horizontal datum set
- Projection and zone
- Vertical datum / height system
- Units correct (m, not ft)
- Correct transformation selected
- Geoid / AusGeoid model loaded if needed
- No mixing of datums in one job
- Project CRS matches the controller / GIS
- Imported data re-projected, not assumed
- Control coordinates in the right CRS
- CRS recorded in the job notes / metadata
- Check point verifies the setup
Study support only — follow your lecturer and the official assessment brief. Nothing here is stored.
How to use this calculator
- Tick each item as you confirm the datum, projection, transformation and software settings for the job.
- Watch the completeness and outstanding list update.
- Clear every item before you collect or process any data.
How it works
Most coordinate blunders come from a wrong or mixed CRS: the datum, projection/zone and height system must all be set, and any transformation (e.g. GDA94↔GDA2020) selected, before data is collected or imported.
This is a browser-only setup aid — record the CRS in your job notes so anyone using the data later knows exactly what it's in.
Worked example
A GDA2020 job in WA. Datum GDA2020, projection MGA Zone 50, heights AHD via AusGeoid, the controller and GIS set to the same CRS, and a check point confirming the setup.
Frequently asked questions
What happens if I mix datums in one job?
Coordinates can be out by a metre or more (e.g. GDA94 vs GDA2020) with no obvious error. Keep one datum per job and transform imported data explicitly — never assume it matches.
Is this official course material?
No. It is free study support mapped to surveying course levels — not official North Metropolitan TAFE content or advice. Always follow your lecturer and the official assessment brief, and check your own working.
