Equal Area SRID for Australia – Best Coordinate System for Accurate Spatial Analysis

australiacoordinate system

Does anyone know the SRID for an equal area projection that is suitable for the whole of Australia?

I realize that I could make my own (which I have done) but I am looking for one that is present already that I can use in both PostgreSQL and Proj4

You could try the GDA94 / Australian Albers (EPSG:3577), or the Australian Albers (EPSG:17365).

[GIS] Area calculation: Albers Equal Area vs Pseudo Mercator

Pseudo Mercator does not have real metres as units. At the equator it fits to metres but the more to the poles you come, the greater the distorsions are. The measurement tool takes care of that, but the field calculator does not.

So you have to choose another CRS. Most UTM CRS are restricted to their defined area, and might produce wrong results outside.

The to_crs method also accepts the full proj4 string specification (or in dictionary presentation), so you can do

gdf = gdf.to_crs("+proj=eck4 +lon_0=0 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs")

without the need for an EPSG code (proj4 definition from https://epsg.io/54012)
