Wellington Sea Level Rise

Jun 2017

A twist on the familiar Wellington coastline showing a map of the dramatic impact of a 9 metre rise in sea level on the city.

In this hypothetical map, a 9 metre sea level rise means that Evans Bay and Lyall Bay are now connected, Miramar has become a harbour and shoreline of Lambton Harbour resembles something closer to its historic boundary. LIDAR contour data provided by the Wellington City Council meant that it was possible to derive this hypothetical new coastline with high accuracy.

I created this design as part of the 7 Day Cartography Challenge. You can check out the rest of the maps I made over the 7 days here.
