Fix Things

Description

Fix things like GSHHSWorld.

Usage

.fixGSHHSWorld(world)

Arguments

world

data.frame – PolySet of polygons for the global shorelines

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).
