[GIS] Equal area world QGIS

coordinate systemqgis

when I use ArcGIS I normally use CRS: Cylindrical Equal Area (World) WKID: 54034

In QGIS I cannot find the same projection. When I re-project my file in ArcGIS and open it in QGIS it says I am using a custom CRS:

  • Generated CRS (+proj=cea +lon_0=0 +lat_ts=0 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs)

Is it true that QGIS doesn't have this CRS? I will use my custom CRS for now but for future projects my main question is: What is a suitable equal area projection with global coverage in QGIS? I was thinking about Lambert but can't find the right flavor.

The code numers 540xy are not official EPSG codes, but rather invented by ESRI to fit the wish for worldwide projections.

QGIS has some of them (naming them wrongly EPSG:540xy). But some are missing, because noone has implemented them. That's the reason why QGIS has to create a custom CRS for it. You can safely use that, or type in 540 in the Filter search box and look what similar worldwide projections are included.

As far as I can see, Lambert projections laea and lcc are only used for parts of the world, not worldwide.
