I'm conducting a research project and i need to identify (using gis and gaez database) the crop suitability index values for maize and wheat with coordinates as input.
So far I've been able to recover the map showing the distribution of the values, but if i click on the pixel to obtain the value, it only returns the value "255" for every location in which I checked.
It is an image and when you click on a pixel it is most likely returning the color value for the pixel for the red, green and blue bands. Do you have a legend or meta data that translates the colors to crop suitability classes? or does the data have a table you can open that provides the classification?
