I am using python script tools for ArcGIS 10.2, under Windows 8.1 64bit.
When I am using the arcpy.GetRasterProperties_management() command, it's very slow to process the data.
For example. I tried to get the maximum value for 14 rasters, if I use the batch mode of the system tool: Get Raster Properties, it uses only 0.19 seconds.
But when I am using python script tools to do this, it basically takes 1 second to print 1 value on the screen. So it takes 15 seconds to get the maximum value of the 14 rasters. So when I have hundreds of rasters to process, it takes too much time.
And this is when the CPU usage is 20%, which is the maximum usage when running ArcGIS on my laptop, sometimes the CPU couldn't even get there, when the usage is only 5 or 6%, it takes one minute to get all the values.
this is the code I use for this part:
for out_raster in out_rasters: try: raster_min = arcpy.GetRasterProperties_management(out_raster,"MINIMUM") raster_min = raster_min.getOutput(0) arcpy.AddMessage(raster_min) except: arcpy.AddMessage("No_data")so is there any way I can increase the speed? Thanks.
