Sample (spatial analyst) bug in 10.5.1.7333

MilesSpathelf1

I have an issue where the sample tool incorrectly reports values from a raster when using a point file. For example a point lies entirely within a raster cell and the sample tool provides a result of "49" when the identify tool correctly provides a results of the actual cell value of "19"

Hmm, I do get the same results as you when I bring in the tif as all bands instead of just band 5. In my table the Nenana__14 is the same as the original band 5. This reports the correct values unlike when I ran the sample tool on just band 5. In that case I only selected band 5 within the tif to bring into ArcMap and ran that with the sample tool.

Do your sample results look like this? I only have 10.6 available. What looks different is what is assigned to RGB if you have 5 bands

MilesSpathelf1

The Tiff has 6 bands

The point shapefile is used for sampling and wouldn't need to have related attributes.

No other layers are in my data frame

For example when I sample band 5 alone I get these values from the Sample tool in the output table

topo_seque 1 (alluvial site) - 49

topo_seque 2 (mid slope) - 48

topo_seque 3 (upper slope) - 44

From the identify tool I get these values by identifying from all layers and selecting each point ID in turn

ID 1 (alluvial site) - 53

ID 2 (mid slope) - 45

ID 3 (upper slope) - 19

Your tiff... info reports a value for R, G, B

Your shapefile just has totally unrelated attributes.

What values are your expecting? and by chance are there other layers in your dataframe?
