topic Raster Resample and pixel value in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/raster-resample-and-pixel-value/m-p/228841#M7918 <HTML><HEAD></HEAD><BODY><SPAN>Hello Forum,</SPAN><BR /><SPAN>I am about to resample raster ( going from 50X50 km to 5X5km) and calculate total pixel value within polygons. I am dealing with a geotiff which has a grid size of 50X50 km. The grid size is really big for some of my polygons. I want to either extract/clip value by polygons or perform zonal statistics. I am thinking to resample into 5X5km so that good number of grids falls inside smaller polygons then perfrom relevant task to get total pixel values within polygons.&nbsp; I wonder how resample works to assign pixel value from 50X50km to 5X5km ? For say, if a grid (50X50km ) has value of 1600. Does it calculate fractional value and assign to each cells to 5X5 km grid ?</SPAN><BR /><BR /><SPAN>Sorry if I didn't make my problem clear.</SPAN><BR /><BR /><SPAN>Thanks.</SPAN></BODY></HTML> Tue, 08 Apr 2014 17:29:54 GMT YamMagar 2014-04-08T17:29:54Z Raster Resample and pixel value https://community.esri.com/t5/geoprocessing-questions/raster-resample-and-pixel-value/m-p/228841#M7918 <HTML><HEAD></HEAD><BODY><SPAN>Hello Forum,</SPAN><BR /><SPAN>I am about to resample raster ( going from 50X50 km to 5X5km) and calculate total pixel value within polygons.
