Hello
We are beginning to do some work with MayaVi2 on oceanographic datasets.
Virtually all of these data are spatially located according to latitude,
longitude and depth which constitute an unstructured grid. For the
visualization to be useful to use we need to display the data using a
projection scheme so that the map is not distorted.
I have not yet found any examples using mapping projections and am
wondering if MayaVi2 can handle this? I assume so, but don't know if
perhaps there is a specific module?
As an example of what I want to create, imagine a map of bathymetry off
the coast of California, and then overlay an isosurface of oxygen
concentration in the water = 1.5 ml/liter (based on vertical profile
data). The profiles were collected on an irregular spatial pattern of
stations along ransects normal to the coast. The vertical samples were
collected at an irregular set of depths on each profile. The final
visualization would resemble a layer of cloud lying across mountain
ranges where the peaks of the mountains and ridges rise above the
isosurface layer. This is a representation of the oxygen minimum layer
in the water column.
