I have two large rasters: One defining zones (private properties, with unique value for each property) and one of land cover change (deforestation data, with values for the year it has been deforested).
What I want is to calculate the amount of deforestation for each year on each property. I will later categorize the properties by property size, but I do not want to do it at this stage. And I would like to be able to plot the results spatially as well.
Also, I am interest on the size of the deforested patches, i.e., adjoining raster cells deforested on the same year. Is there a way to calculate this area without transforming into polygons?
I know that using polygons I could use intersect and it would give me exactly what I'm looking for. But these are VERY large rasters, it is simply not possible to use polygons for this. I looked into Zonal Statistics but as values for deforestation are categorical, that doesn't solve it. I'm currently trying to fix a bug while doing Tabulate Area (backgoung processing crashes), but still I wouldn't be able to plot the results.
Is there any different approach for this? I feel it's a simple query that I just haven't found the right tool(s) yet... I'm using ArGis 10.2.2
