Calibration of survey equipment
Surveyors have a legal obligation to ensure that their equipment is standardised (s. 20 of the Survey and Mapping Infrastructure Regulation 2014). For distance measurement, this means that measurements are traceable to the national standard. This can be achieved by doing a comparison test on an electronic distance measurement (EDM) calibration range which has a current Regulation 13 certificate under the National Measurement Act 1960.
Although tests carried out during instrument servicing provide a level of confidence that the equipment is performing correctly, they do not give legal traceability of length measurement.
To assist surveyors, we maintain electronic distance measurement equipment (EDME) calibration baselines throughout Queensland.
EDME comparison procedure and booking sheets
We recommend that surveyors use the following procedure and booking sheets to achieve legal traceability of length.

- EDME comparison booking form (PDF, 165KB)
- Meteorological observation booking sheet (PDF, 81KB)

- Gold Coast
- Mica Creek
- Townsville 2 – read warning notice below
For enquiries regarding baselines, software and calibrations, contact the appropriate Regional Calibration Officer listed on the baseline information pages.
Pillar 2 is suspected of a disturbance. Use discretion when processing observations to and from this station.
EDM calibration processing software
We have worked with our counterparts in other states to develop calibration processing software for use nationally.
The baseline software can be downloaded from the link below. Read the software guide before downloading the software to ensure correct operation.
In addition to the software, you will also require the instrument-specific values, which can be obtained from the relevant manufacturer. The instrument values required are shown when adding a new instrument in the software.
