Hi,
I'm trying to calculate the leaf area index of different vegetation species at each state in the US and I'm using a netcdf (.nc4) raster file for the LAI and a usual shapefile (with polygons) for defining the state boundary. I converted the net cdf file into a raster file using the "Make NetCDF raster layer tool". I'm using the Clip tool (< Raster Processing < Raster < Data management tools < Arc toolbox) in the arctool box to clip the raster layer and the polygons. So in this case, my output extent are the states that I choose from the shapefile and the Input raster is the raster layer ofcourse. I also checked the "Use Input Features for Clipping Geometry" option so that the raster dataset is clipped onto the perimeter of the shapefile.
Here is my question: Sometime, there are additional pixels that are created in the output raster dataset, that are actually not present in the original input raster layer. And these pixels also have a value associated with it, which is a cause of concern since some states which should actually have a zero value in it, have a random number in the output file.
Could someone explain what's happening or the possible reasons for this?
Thanks!
