I'm trying to extract values from a raster file dataset (called land_use) to polygons (in a file called Hydro_buff) that I have created. I read a few questions on that topic but some other issues come up.
I have tried "zonal statistics" but I get a raster output when I just need a feature output. So I tried using "zonal statistics as table" to then join the two tables together (join to Hydro_buff) but it doesn't work because for some reason I go from 74 034 polygons to just 31 426 after using zonal statistics as table so lot of the polygons have Null value. All of my polygons have a UID that I created using the "create Unique ID" tool.
I checked the extent of both of my files and only 10 000 polygons don't overlap the land_use
Does anyone know what the problem is ?
