- Equal Area SRID for Australia 1 answer
I have a polygon shapefile showing mining areas across all of Australia. I want to calculate the area for each of the polygons however they have been provided in a Geographic Coordinate System (GDA_94).
Can anyone tell me what projected coordinate system I could use that would enable me to calculate the areas of each polygon?
Will I need to transform the data and how might this affect the calculations given the size of Australia (i.e. it covers multiple GDA or UTM zones)?
