I have a question about zonal statistics as a table. I have 200 circles (1 mile radius) and need to extract the mean value of a raster dataset to the individual circles. So each circle would have a mean value of the raster grid underneath it. I thought the best way to do this is Zonal statistics as a table and then join the table to the feature class file using the circle ID. However, when I go back to double check the results some circles have 'null' values, which makes no sense because there is a raster underneath it. What is happening? and how can i fix it?
