I have a very large raster for which I am trying to compute zonal means using a shapefile that covers the same extent but has hundreds of thousands of individual polygons as zones. Trying to just use the large shapefile as the input feature zone and the raster as the value raster doesn't seem to...

I'm using a Ublox M8T with a Tallysman antenna which I have used with U-Center 8.818 and have written a ubx file. This ubx file can be taken into RTKLIB v.2.4.2p10 and I can create a nav and obs and a pos file by using the convert button in rtkconv. There is a nearby ( 2 miles ) continuously...
