https://community.esri.com/t5/arcgis-online-questions/sampling-random-generated-points/m-p/1029899#M38637 <P>Hi, I am using Arc GIS pro 2.7.1. I have been trying to generate a table to show the values of cells from two rasters that I have (NDVI and a classified image) associated with some randomly generated points. I am using the Sample tool to do this.</P><P>I was able to sample my own GPS data just fine, but when I attempt to sample the random points that I generated it gives me the error that the input feature class does not have a spatial index. Also when I attempt to generate a feature class through this tool I end up with an empty table.&nbsp;</P><P>The random pts have X Y data associated with them, so I am not sure why it isn't letting me sample them like I did with my own data.&nbsp;</P><P>What does it mean that the random pts feature class doesn't have a spatial index? How might I be able to fix this?&nbsp;</P><P>Thanks!&nbsp;</P> Wed, 24 Feb 2021 05:27:20 GMT Cheriejn 2021-02-24T05:27:20Z https://community.esri.com/t5/arcgis-online-questions/sampling-random-generated-points/m-p/1029899#M38637 <P>Hi, I am using Arc GIS pro 2.7.1.
