[Manifold-l] Surfer .GRD import

[Pat Waggaman]

In bathymetry, back when we were doing a lot of it - we needed the 
same Surfer to Manifold integration.

Our workaround - and this is several Manifold versions ago - was to 
export CSV from Surfer and then import those tables into Manifold.

East - West "squishing will occur with the cos(Lat) x 60 nm of 
"Longitude compression" as you near the poles.  If that is a problem, 
raise it as a separate issue, there are questions here of the source 
data projection and what you want as a finished product.

Cheers,

Pat
