I'm working with a NETCDF file and am running the following code and the nodata option of the CopyRaster command doesn't appear to be working as I expect. The CopyRaster successfully creates the raster but in the properties the maximum value is still displayed as the value in the CopyRaster command. I've also tried entering the 36-digit number instead of the scientific notation and I get the same result. I'm not sure if it's the large value that's the problem or if I'm overlooking something.The nc variable I'm working with has the large value for water bodies and the remaining cells between 0-1 (floating point) so if the nodata option worked I'd expect a max <= 1.import arcpy
from arcpy import env
arcpy.CheckOutExtension("spatial")
from arcpy.sa import *
arcpy.env.overwriteOutput = True
arcpy.env.workspace = r"G:\data\NETCDF"
NetCDFFile = r"G:\data\NETCDF\year.nc"
GDB = r"G:\data\NETCDF\GCM\Hist_Output_Part_Burn4.gdb"
NetCDFFileProp = arcpy.CreateObject("NetCDFFileProperties", NetCDFFile)
##for i in range(0,int(NetCDFFileProp.getDimensionSize("year"))):
for i in range(0,1):
## # convert month from a floating point to an integer (prevents error in naming raster)
DIMENSION_VALUE = int(NetCDFFileProp.getDimensionValue("year",i))
print 'Working on Dimension Value: ', DIMENSION_VALUE, '(index ', i, ')'
# delete existing raster if it exists
if arcpy.Exists( GDB + "\\" + "year" + str(DIMENSION_VALUE )):
print '--- deleting ', "year" + str(DIMENSION_VALUE)
arcpy.Delete_management( GDB + "\\" + "year" + str(DIMENSION_VALUE ))
# create raster layer from NetCDF file
arcpy.MakeNetCDFRasterLayer_md(NetCDFFile, "part_burn", "lon", "lat", "year_"+str(i), "", "year " + str(DIMENSION_VALUE))
# create raster
arcpy.CopyRaster_management("year_"+str(i), GDB + "\\" + "Hist_PB_"+str(DIMENSION_VALUE+1895), "", "", "9.96921e+036")
#reclass raster
#Notify when finished
print "Finished!"
Thanks,Mike
