The team at Miromaa Aboriginal Language & Technology Centre developed these sets of icons initially for their app developments. They have designed these to represent the many word categories or semantic domains used in documenting languages, They are making these available for use to help Aboriginal and Torres Strait Islander and other Indigenous communities map language and other elements using Google's mapping tools (ie: Google Earth, Google My Maps) or other applications that accept custom icons. Miromaa will continue to add to this collection of icons.
At the 2019 Indigenous Mapping Workshop held in in Perth, Google and Winyama made available for the first time their initial set of icons to help Aboriginal and Torres Strait Islander communities map cultural and natural resources using Google's mapping tools (ie: Google Earth, Google My Maps) or other applications that accept custom icons.
These icons were designed by Dennis Golding, a Freelance Designer with Google’s Creative Lab and a descendant of the Kamilaroi/Gamillaraay people from the North West of New South Wales to represent a broad range of Indigenous experience like subsistence harvesting, cultural and sacred sites. This set of icons will grow over time.
