I attempted to use the Extract Values to Points tool in ArcGIS Pro 2.1.2 with a set of about 1,000 points and a single band raster. Everything I tried resulted in null values or -9999, which I understand means null. I switched to ArcGIS Desktop 10.4.1 and used the same tool with the same data to perform the same task and it worked just fine. Is there something new about the way Pro is using this tool? Thanks!
