Thanks Bill and Ian,While I might still try the warped 3D cone, I am currently focusing on creating an ellipse at descrete points along the radar radial. I have sucessfully created the ellipse and will soon map it to lat/lon/elev coords and resample the terrain data.
My new question with this technique is can VisAd tell me the percentage of data that fills the ellipse?
More specifically, if I use a Gridded2DSet (ellipse) to resample terrain data (lat,lon)->alt, is there a (simple) way to calculate the number of alt values that have been sampled with respect to the size of the ellipse?
Eg. ******** * * * | * * || * * ||| * ******** 20% of the ellipse is filled by alt values. Thanks for your help! -kevin.
