Points that intersect polygons and points that don't

I have a few thousand points in an SDE layer and I need to see which points intersect or overlay a polygon layer (hundreds of polygon features). Intersecting points will get a risk value assigned to them (I was thinking through a test filter and attribute creator). Non intersecting points just won't have a risk value and all points whether intersecting or not get written to a point featureclass I already have created in SDE. I've tried PointOnOverlay, Intersector, and even SpatialFilter but I must be setting this up wrong. Any ideas? Many thanks

pointonareaoverlayer should work, points will get an overlap value of 1 if they intersect 1 polygon and so on. Are your 2 datasets in the same coordinate system?

Hi @jbears40,

If none of the points seem to be overlaying the polygon, please use Inspectors to check the data right before the overlayer or SpatialFilter, to ensure that it does graphically overlap.

If the points and polygons have different coordinate systems, they may need to be reprojected before overlaying.

UTM and BLM lol.. one dataset was in UTM 27 15N (meters) and the other was in BLM 27 15N feet so that has to be what the issue is. I'll make sure everything is in the same coord system and try PointonOverlay again. I'll respond back and accept answers if that works. Thanks for the fast advice everyone!
