Re: Gridded2DSet

```
Once again, Don, you save the day!

Higher Resolution:

Lower Resolution:

```
"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!

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.
