I am using ArcGIS 10.8. When I use point feature class from file geodatabase as input to Sample tool (using OBJECTID as unique ID field, see 1st attachment) output sample table has duplicate rows for point with same OBJECTID (2nd attachment). Environment setting extent, cell size and snap raster all set to raster in question.
I can get sensible output by converting points to raster, but it is an extra step I am trying to avoid.
Anyone has the same experience?
