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.
