I'm trying to map (using ArcMap 10.6.1) some climate change data and I'm not entirely sure how to classify the raster datasets. For this work I am focusing on four different climate change scenarios:
-2040 RCP 2.6 -2090 RCP 2.6 -2040 RCP 8.5 -2090 RCP 8.5 (RCP is epresentative Concentration Pathway and relates to greenhouse gas emissions, the lower the number the better....)
I'm focusing on things such as temperature + precipitation changes in any of the above four scenarios.
How should I classify this data?
Should I have the same number and range of classes for any given scenario using Manual classification, or should I use Equal Interval for each of the given scenarios?
My gut feel is that values should remain the same over the four different scenarios, however in the RCP 2040 it then becomes difficult to highlight any changes. I also am wary of adding too many classes (trying to stay below 5, 7 max) as things start looking a bit too complicated the more classes that are added.
