on the source (zip) files -- you wrote a 3601x3601 tile needs ~1.5G.  that is
~115 bytes per pixel; likely, some/much of that information will not be
required.  suggest recoding those, to a custom file format.

on the mesh2 storage -- what if meshes were only created on-the-fly[*], when
needed for rendering that part of povearth?  sure, performance hits everywhere,
but within budget.

another "budgeting" option would be to focus on a single continent, initially,
and only produce those meshes.  (maybe, when you retire, your pension will allow
you to buy more cloud-storage.  :-))

[*] ini file 'Pre_{Frame,Scene}_Command'.
