NetLogo 7.0.0-beta2:

gis:set-coordinate-system

gis:set-coordinate-system system

Sets the global projection used for projecting or re- projecting GIS data as it is loaded.

The latter is preferred because it makes the code much more readable.

The same limitations on WKT support apply as described above in the documentation for load-coordinate-system
