Pulling data from external sourcesFreely-available baselayers

• Climate

• Land cover

• Topography

• Geology

• Soils

• Fire frequency

• Nature reserves

More biological observations• Biocollections from

around the State

• Photographs and additional observations collected by various users

• Users can access data and its metadata via our Online Portal, Holos. Holos comes with built-in searching, charting, visualization and analysis tools

• The Data API’s open framework allows third-party developers to write their own tools.
