Once again, Don, you save the day! Higher Resolution: http://www.cimms.ou.edu/~kmanross/VCPRPE/KIWA-hiResAP.gif Lower Resolution: http://www.cimms.ou.edu/~kmanross/VCPRPE/KIWA-lowResAP.gif"Resolution" is defined by A) the number of points along the radial line and B) the number of radials sampled per degree azimuth.
Now, is there a way to connect the dots so that I have several discrete 2D "blobs" instead of rows of points? I.e., from the above examples, you can make out 2D features that basically indicate mountain tops.
Thanks again! -kevin. Don Murray wrote:
Kevin- Do you want to just plot points where the intersections occur? If so, then just create a FieldImpl of your points as: (index -> (lat,lon) The Gridded2DSet would indicate that there is some relation betwee all the points. On a 1D manifold, this would be a line (like your selector line) and on a 2D manifold, this would be a grid. As just points in a FieldImpl, they should just show up as points. Since they will be discontinous, this seems like a good approach. You could use a ConstantMap to PointSize to set the size of the points. Another approach would be to use the same Gridded2DSet that is your domain of the PPI panel and create a FieldImpl of (lat,lon) -> (value) where value would be some number (not NaN) at the set indexes where the intersection occurs and NaN everywhere else. Map value to RGB and it would give you a color map of the intersection points. you could use valueToIndex with your array of lat/lons to figure out which points should be NaN and which should have a value.I hope that is clear, but am certainly willing to explain further if needed.
