Land disappearances

[EllingDJ]

Land masses seem to drop out "above" -55 degrees latitude when producing non-stereographic Antarctic maps.

A: basemap(limits = c(-72, -35, -60, -40), rotate = TRUE)

B: basemap(limits = c(-72, -35, -57, -35), rotate = TRUE)

Land masses disappear above -55 in A but not in B.

Hmm...this is because the antarctic_land object extends to around -55 latitude, not -30 as it should:

sp::plot(antarctic_land)

In A you plot the antarctic_land and in B you plot dd_land. A clear bug. The solution is to remake antarctic_land and update the ggOceanMapsData package. I will close this issue once it is done.

Perfect. Otherwise great package. Thanks Mikko.

This issue should be fixed in ggOceanMapsData commit MikkoVihtakari/ggOceanMapsData@c5fbb78
