I am using National Land Cover Data from Multi-Resolution Land Characteristics Consortium. I am looking at central states for changes in forest versus grassland cover classes between 2012 and 2015. The data are rasters with land cover classes that have names and values for the classes and area values for the class coverages. How do I find the change from, for example, mixed forest (#143) to shrubland (#152), during the years mentioned above? I am hoping to get a new raster that will show where the changes occur and that includes a table with some kind of count or indication for the amount of land changed. This is probably a basic type of analysis, but something totally new to me. Would I do this with Raster Calculator or another function in the Spatial Analyst toolbox? I'm not even sure how ask the calculator for a specific class in a field, in a layer. For example:


or some such.
