Hi Don,I prefer to have my data shaped like (lon,lat,alt)->foo but my domain set can be 100x100x25. I can't use a Linear3DSet because my altitudes are not regularly spaced and a Gridded3DSet requires 250000 values, most of which are redundant. As I understand it, I could define the set as a ProductSet of 3 Gridded1DSets with 225 (100+100+25) values. Just thought I'd try to reduce memory usage a bit. No Biggie.
Thanks, Doug Don Murray wrote:

However there have been other VisAD improvements that help, like the CartesianProductCoordinateSystem which allows you to make a "product" of multiple CoordinateSystems. Is there a particular need to use ProductSet? As you know, there are many ways to skin the same cat in VisAD.
