I have a bunch of UK polygons that are saved in my PostGIS database as WGS84 projection. I would like to calculate the area of these polygons using
According to this answer I can save these polygons in any equal-area projection to do this. Is it really true that I can use any equal-area projection? For example, if I save them in US National Atlas Equal area (SRID 2163) will that work?
In any case, is there a UK-focussed equal area projection that it would be most appropriate to use?
