Identifier: ll_proj
Identifier: ll_projprojection
The longitude/latitude projection. This is a read-only identifier.
Other longitude/latitude projections with a shifted longitude may be created when wraparound for Pacific Rim display is required. This is achieved by copying ll_proj to a new projection and redefining the origin. Shifts in latitude are ignored.
projection ll_pacrim = ll_proj
ll_pacrim.origin = (180,0)
