I am using ArcGIS Pro (2.4.2) to analyze a 5-band multispectral image captured with a Matrice 200 (UAV). All image processing has been done with Agisoft Metashape, which includes calibrating spectral reflectance with a calibration panel and stitching the imagery together into a final orthomosasic.
When I look at the imagery in ArcGIS, I notice that my RGB values are very, very high. Much higher than the typical 0-255 RGB values that is expected for imagery. An example of the values that I am receiving is included below:
What is the reason for this, and how could I convert them back to the 0-255 range?
