I am building a model with one raster layer defining where a certain plant is growing and several other raster layers with climatic conditions such as rainfall, temperature etc underneath the original. What I want to achieve in my model is to be able to define the minimum and maximum value of every climatic condition where my plant currently exists. Once I have that information defined I then want to predict where my plant can exist in the future by identifying the same conditions in future climates. Any help would be much appreciated. I'll try and be more specific with just one question... Can I from the Raster Calculator interrogate two raster layers by asking: Where this plant is present on one raster, tell me the max and min temperature on the second raster? I'd just like to know if the Raster Calculator can handle WHEREs and IFs please?
