Hi,

I have a hard time trying to extract pixels values from a raster. I tried to use Extraction function called "sample" by using the raster itself to extract values but it gives whole numbers as values extracted instead of decimal values. I need these decimals values but I have to idea how to get them. The raster show decimals values with Identify function.
Is there another way to extract pixels values into a table?

Thanks!

The reason you only see integer values is because the only way a raster will show an attribute table (including after extraction) is if it is an integer raster. To get non-integer raster values you would have to use the extract values to points tool. (Or other extract values to... tools)

Hope this helps, if you explain the purpose of extracting the values from your raster I could help a bit more.
