I am using zonal statistics as table for calculating statistical parameters in different size disc and I also use a raster layer(canopy cover) as input. I have reclassified NODATA as 0 value. I have used 780 points for creating different size buffers (outside buffers) around these points. My buffers overlap but are not dissolved. Then I have used these buffers seperately and their FID and a raster layer as inputs of zonal statistics as table. Calculations are doing well for small buffers (r=50,100,200,500m), but the result tables just includes 766 rows for my 1000m buffer and 750 rows for my 2000m buffer. How I can solve the problem?
I found a solution: The problem is that zonal statistics as table does not support overlapping features. Fortunately,the Spatial Analyst Supplemental Tools, created by Esri, includes something called Zonal Statistics2 and this can be helpful in this case.
