Hi Roshan - Yes I used Euclidean distance in ArcGIS and clipped to my AOI/converted to the same projection in ArcMap. I then brought the file into LCM using the GDAL conversion utility and had to u...

Area of Interest
What is the largest area of interest you have seen evaluated by LCM? There is some interest at my work to apply LCM at a country or even global scale. I have only ever seen spatial modeling done at...
