I converted a Landsat-8 image from 16-bits to 8-bits in ArcGis. Now I want to extract the new values but there is something wrong. I have two different Z values: pixel and stretched values. The most important values are stretched (0-255) but I cannot extract. When I use the tool "Extract Multi Value to Point" the result is 255 for every point.
Somebody know what can I do to extract the stretched values or what is wrong with the process?
Thank you all
it extracts the actual pixel value, not the stretched value
perhaps you need to go through this process first Color correcting raster data—Help | ArcGIS for Desktop
