I am running a hot spot analysis for clusters of points within Myanmar using model builder. As the country is long and has many coastal and inland borders, I think the lack of data outside the country is affecting the result. I created a raster to mask out areas outside the country so the analysis would only be inside the borders. I set the geoprocessing environments using the mask but it didnt make any difference to the result. Is there a way to set the mask within model builder? Or any other hints?
