Get Raster Properties获得栅格的信息

Summary

Returns the properties of a raster dataset.

Usage

• The property returned will be displayed in the geoprocessing window.

Syntax

GetRasterProperties_management (in_raster, {property_type})

Parameter	Explanation	Data Type
in_raster	The input raster dataset.	Raster Layer
property_type (Optional)	The property to be obtained from the raster dataset. <esri_enumhead><esri_enumvaluehd><esri_enumdeschd> MINIMUM —Returns the smallest value of all cells in the input raster. MAXIMUM —Returns the largest value of all cells in the input raster. MEAN —Returns the average of all cells in the input raster. STD —Returns the standard deviation of all cells in the input raster. UNIQUEVALUECOUNT —Returns the number of unique values in the input raster. TOP —Returns the top or YMax value of the extent. LEFT —Returns the left or XMin value of the extent. RIGHT —Returns the right or XMax value of the extent. BOTTOM —Returns the bottom or YMin value of the extent. CELLSIZEX —Returns the cell size in the x-direction. CELLSIZEY —Returns the cell size in the y-direction. VALUETYPE —Returns the type of the cell value in the input raster: 0 = 1-bit 1 = 2-bit 2 = 4-bit 3 = 8-bit unsigned integer 4 = 8-bit signed integer 5 = 16-bit unsigned integer 6 = 16-bit signed integer 7 = 32-bit unsigned integer 8 = 32-bit signed integer 9 = 32-bit floating point 10 = 64-bit double precision 11 = 8-bit complex 12 = 64-bit complex 13 = 16-bit complex 14 = 32-bit complex COLUMNCOUNT —Returns the number of columns in the input raster. ROWCOUNT —Returns the number of rows in the input raster. BANDCOUNT —Returns the number of bands in the input raster.	String

Code Sample

GetRasterProperties example 1 (Python window)

This is a Python sample for GetRasterProperties

import arcpy
from arcpy import env
env.workspace = "c:/data"
#Get the geoprocessing result object
elevSTDResult = arcpy.GetRasterProperties_management("elevation", "STD")

#Get the elevation standard deviation value from geoprocessing result object
elevSTD = elevSTDResult.GetOutput(0)

GetRasterProperties example 2 (stand-alone script)

This is a Python script sample for GetRasterProperties

import arcpy
from arcpy import env
env.workspace = "c:/data"
#Get the geoprocessing result object
elevSTDResult = arcpy.GetRasterProperties_management("elevation", "STD")

#Get the elevation standard deviation value from geoprocessing result object
elevSTD = elevSTDResult.GetOutput(0)
