Display values of mosaic data set

BenasPekarskis1 — Sun, 14 Aug 2022 17:39:25 GMT

I have applied raster function to calculate NDVI for Sentinel 2. The values of NDVI supposed to be in between -1 and 1. When I click to Identify the pixel value, I believe I get correct values, lets say 0.65, but in contents pane the values are displayed differently. See image.

Question:

How shall I set up symbology so it displays correct values in Contents Pane? In addition, because I use Raster Templates, it would be useful if I could incorporate this symbology into the Raster function.

Regards,

Ben

check your 'symbology', perhaps your color ramp is stretched. You can change the symbology type and the ranges there

Benas,
did you create your own "RFT" to achieve this, or use an Esri-supplied one? We have quite a number of optimized ones, resulting in Legends like this:

if you want to create something like this yourself, see this post: Classified Raster - Legend issue ... the recalss and attribute table process is what you are looking for.
If you want to use some of the ones we have developed, download this zip: https://www.arcgis.com/home/item.html?id=e6e1f20cb0374d28a6eed24f5c2ff51b and then open it, go to the folder ../Parameter/RasterFunction Templates and then analyze/use the one you need.

interesting!
