The Extract Values to Points tool in ArcGIS Pro extracts and records the cell values of a raster in the attribute table of an output point feature class. In some cases, running the tool returns the value '-9999' instead of the correct raster cell values.Cause...
If the Input point features value is a point feature class with no spatial index, a warning will be issued. To improve tool performance for an input with a large number of points, create a spatial index. See the Add Spatial Index tool for more information. The tool will fail to execut...
