I have to calculate the area of different land classes like forest,barren land etc from my classified land use data at different elevation zones at an interval of 100m. I have DEM of my study area also.

I have tried Zonal Statistisc as table tool and got the output table but i dont know how to identify the type of land class from the table. Can somebody give a solution? enter image description hereenter image description here

    Use Reclassify to divide your DEM into elevation zones, then use Zonal statistics to get land class area per DEM zone. – BERA Dec 14 '18 at 7:28
  • Thank you for the answer but may i know how to identify land class type from the above table .I have uploaded screenshots of zonal table and my classified land type training set .How can i understand which land type is specified in each row in the table.I am new to arcgis .Can someone help me. – Green man Dec 17 '18 at 7:15
  • i have converted it into jpg format..is it visible now?? – Green man Dec 17 '18 at 7:31

I think you would like to get something like this: enter image description here The codes are Corine Land Cover values, heights are in meters.

Expanding on BERA's answer I would approach this workflow like this: 1. Reclassify the DEM raster from exact elevation values to elevation classes based on 100m steps 2. Convert reclassified raster from raster to vector polygons enter image description here 3. Convert the LandUse raster to polygon enter image description here 4. Run Tabulate intersection on the two polygon layers giving the percentage of each Land Class in each elevation area. enter image description here 5. Export the values to excel and build a nice 100% stacked bar graph. Just use vlook-up to get the values for the clasess in order to get thea area for each class: enter image description here
