Hi everybody! I have been struggling to clip my NDVI dataset to two polygons surrounding my research sites. When I do so it gives me this weird outcome where the values are seemingly inverted. You can see in the image the original is on the right and the clipped is on the left. The color ramp is the same for both. I'm wondering what I may have done wrong here? Is there a different process for clipping something like this? Basically i just want to get to the point where I can compare NDVI based on the areas of my two research sites. I don't know if there is maybe another way to get around this.
Weirdly the color ramp stays the same. So all the lower value points in the original are higher value in the clipped version and vice versa. I'm not sure what you mean by what format? When I run the tool it just saves it as a raster dataset.
The format of the Raster (File GDB Raster dataset, TIFF, IMG, etc)?
Does clicking the pixels in the same place also gives opposite values in popup? Then there some issue with the process.
In case the values are same (and symbology is different), then
- remove the clipped layer, add the layer again.
- Execute the Clip tool again. Save the output raster in TIFF format (*.tif) in a basic folder (not inside a GDB).
- Restart ArcGIS Pro.
