I have downloaded 2 chlorophyll maps which generally have cell values of 0-255.
How can I convert these into real world values?
I have downloaded L3 choloprhyll data maps. I have extracted and attempted to convert the cell values in R, with no luck.
Is this possible in Arcmap and how would it be achieved?
# DN = digital number / cell value / cholorphyll L3 data# value = 10^[(DN * slope) + intercept]
# raster = Modis cholorphyll sattelite image
# Code ran in R
((values(raster)* 0.015) -2.0)^10)
# Does not return real world values (values between 0-64 mg m-3)
Linked below is one of the raster images I have attempted to convert into real world geophyiscal values, which was downloaded from Giovanni (after clicking the link, click plot, select an image and download as a TIFF. Attachment limits prevent me from directly uploading image. OR just download image attachment in comment below)
How can I convert the pixel values (0-255) of a cholorphyll L3 TIFF image into real word values, using Arcmap?
