Context:

• some projects focused on the South Pole require a web visualisation using TerriaJS, and hence need data to be projected in 3031 CRS
• currently that's not possible

Options:

• use 4326 for a 3D view
• visualise data only in the 2D view based on Leaflet and have a 'South Pole/3031" mode that users can enable
• Some examples of Leaflet based South Pole web maps: http://www.soosmap.aq/ and https://nilas.org/#0/-72/8

What would option 2 entail?
