Hi! I am trying to use ArcMap 10.4 scatterplot matrix to show the correlation between tornado strength and elevation. I have a 10m DEM (32-bit floating point) for the state, along with survey points. I'm having trouble converting the DEM raster values to point values, in order to graph them on the scatterplot. When I use Spatial Analyst's "Extract Values by Points" tool, and it keeps giving me -9999 placeholders for the elevation column. I checked and both of my spatial references are NAD83 UTM, so it's not a spatial/projection issue. I can't figure it out. HELP!
