Hi all,

I am currently using VisAD to render my data, but want to take OpenMap
for a spin also. This means extending Layer and writing DODSLayer or
NetCDFLayer. But I don't really understand how extending layer actually
does the trick, which also results in my not really understand how to go
about extending layer.

What I know how to do is to get the array of floats that represents my
data samples, and munge them into whatever form necessary - be that a 3d
array, or objects, whatever, I can slice and dice to the appropriate
data representation. What I don't understand how to do is to create the
requisite objects inside OpenMap. The FAQ says, "Once you have that, you
can create a list of OMGraphics that OpenMap will place on the map". Is
there an easy way to go from my data arrays to the OMGraphics list? I
have gridded data which I would like to represent as either contour
lines or color-shading, and point data which I would like to represent
as point measurements.

Anyway, I know I don't have the most perfect grasp of the openmap
system, but I'm hoping the user community won't mind some newbie questions!
