Lowest Points contains duplicate values

[adgiles]

Running the lowest points tool in ArcMap, it seems that the results contain a point for every pixel in the lowest area, that are close together and of similar value, using the sample elevation in the testdata folder you get the following results:

In this case the lowest points returned 2046 points as a grid around the lowest elevation values:

I think the tool would be better if neighbouring pixels of the same values are converted to polygons and the center point of each polygon returned.

Fix applied in PR #243, if change accepted please can somebody verify

@adgiles That is correct. If your selection area includes a lake (which should be a low point) then the surface of the lake should have the same lowest values. w.r.t. spacing the number and arrangements shows the area of the lake. Reducing to a single point obscures this (a reason why it's called Lowest Points, and not Lowest Point)

[adgiles]

ok if that is the way the tool is designed and expected to work then PR #243 can be ignored

@adgiles not ready to kill the creativity yet. So lets use this as a chance to think about improving this guy. So if a multiple point output doesn't work for flat, low areas... should we think about alternatives, like making an optional output low area polys?
