Focal Statistics, memory issues after multiple calls

WeiMao — Thu, 28 Mar 2024 21:46:03 GMT

I'm writing some code using python to call arcpy. I found that after I called focalstatistics many times, arcgis pro would just crash and there was no record.

My code is shown as follows, and self.smthc = 7, and factor is 500. Raster is just a DEM downloaded from USGS, and the resolution is 1m. It's about 2,000 rows and 2,000 columns.

def smoothDEM(self, raster, factor):
    """smooth the raster factor times"""
    neighborhood = arcpy.sa.NbrRectangle(self.smthc, self.smthc, "CELL")  
    smoothed_dem = raster
    for i in range(factor):
        smoothed_dem = arcpy.sa.FocalStatistics(smoothed_dem, neighborhood, "MEAN", "DATA")
    return smoothed_dem

The recode from Windows Event Viewer is shown as follows,
