Tutorial: Map Tour of Survey Mark Locations

This tutorial takes you on a guided tour of notable survey mark locations across multiple Australian jurisdictions. Each stop uses a fly-to action link to navigate the map to a specific location. Click each link to fly there and explore the marks in the area.

info

Remember to switch the active jurisdiction in the header dropdown to match each stop on the tour. Survey marks are only visible when the correct jurisdiction is selected.

Comparing jurisdictions​

As you visit each stop, notice the differences between jurisdictions:

  • Data schemas — Each state exposes different metadata fields for survey marks. See the jurisdictions reference for details.
  • Symbology — Mark type icons and colours vary by jurisdiction. The Layer Manager shows the available mark types for the active jurisdiction.
  • Mark density — Urban areas generally have more marks than rural areas, but density varies by state.
tip

Use the Layer Manager to toggle specific mark types on and off as you explore each location. This helps you focus on the mark types most relevant to your work.
