Fix Things

Description

Fix things like GSHHSWorld.

Usage

.fixGSHHSWorld(world)

Arguments

Details

Determine PID of Antarctica, which is used to extract the current Antarctica. The continent is rebuilt from left to right, creating a new, very wide Antarctica. It is then clipped and merged into the existing world (with other polygons).

Value

A revised PolySet of the world with a peeled version of Antarctica.

Note

This function is not called by any PBSmapping functions. It can be used after 'importGSHHS' uses ylim=c(-90,90).
