�?�Both Input Features and Near Features can be the same dataset. In that case, when the input and near features are the same record, that result will be skipped so as not to report that each feature is 0 units from itself.
�?�The input features can be a layer on which you have performed a selection. The selected features will be used and updated during the execution of the tool. The remaining features will have the values of the newly created fields (such as NEAR_FID and NEAR_DIST) set to -1.
I still have to figure out how to exclude dissimilar species. There are enough different species that I want to avoid having to break them out into separate feature classes.
The problem is, if I do a spatial join of points to polygons, ArcGIS grabs the info from either polygon, so I can't be sure that a given point is related to the proper polygon. If I do a spatial join of polygons to points, ArcGIS grabs the info from whatever point is "closest" to the polygon, whether or not the point belongs to the polygon. So no matter which way I perform the join, I can't trust ArcGIS to have joined polygons to the points that generated them.
How can I get the proper polygons' identifier into the attribute table for the points, but only if the point belongs to the polygon?
Much head scratching here.
Thanks for any ideas.
