  • providing mapping control over NSW for aerial imagery capture and Light Detection and Ranging (LiDAR) remote sensing
  • using drones to digitally capture mapping information of essential telecommunications tower infrastructure for NSW
  • preserving the NSW State Control Survey marks and the cadastral fabric through the Preservation of Survey Infrastructure process
  • writing legislation, directions and guidelines for best practice standards related to a variety of survey activities
