EDM Baseline software
The EDM instrument calibration software called Baseline enables users to calibrate their EDM instruments using one of three WA calibration baselines. An updated version of the calibration software is released every two years after the re-calibration of the EDM instrument baselines. Re-calibration was last completed in July/August 2021.
The current distribution version 2021.09.02 contains baselines named Curtin 2021, Kalgoorlie 2021 and Busselton 2021 in application Version is 126.96.36.199. These replace the Curtin 2019, Kalgoorlie 2019 and Busselton 2019 baselines in Version 188.8.131.52 that should no longer be used for EDM instrument calibration.
The software runs on Windows OS (32 and 64bit). If you have issues running the software after install, try re-installing in a new directory.

Note: Baseline software source code is available for developers on GitHub.
Digital level bar coded staff calibration
A barcode staff calibration range has been established on the Land Surveyors Licensing Board's examination site at Boya and consists of two observing pillars and a series of 21 stainless steel pins set in a solid granite outcrop. Landgate regularly monitors and remeasures the test range to ensure its ongoing accuracy and stability.
Landgate now offers an online staff calibration data processing service to ensure staves are calibrated using the latest range data. You can access the application from https://staffcalibration.es.landgate.wa.gov.au/. Note that the application may take 30 to 40 seconds to load.
This service replaces the previous downloadable user processing “Staff” software application.
GNSS testing facility
Landgate maintains GNSS testing facility located at Curtin University. The GNSS network consists of 5 concrete pillars that are regularly monitored (horizontally and vertically) to ensure its stability. This GNSS test network guideline [PDF 0.5MB] is also provided to encourage surveyors to take a uniform approach when testing their GNSS equipment.
The GNSS testing facility is available at Curtin University, Kent Street, Bentley, 24hrs 7days a week.
