栅格数据集属性 (arcpy)

摘要

Describe 函数将返回栅格数据集的以下属性。还支持数据集属性。

栅格数据集将返回 "RasterDataset" 的 dataType。

属性

属性	说明	数据类型
bandCount (只读)	The number of bands in the raster dataset	Integer
compressionType (只读)	The compression type LZ77 JPEG JPEG2000 None	String
format (只读)	The raster format Grid ERDAS IMAGINE TIFF	String
permanent (只读)	Indicates the permanent state of the raster. False if the raster is temporary, True if the raster is permanent	Boolean
sensorType (只读)	The sensor type used to capture the image	String

Raster Dataset properties example (stand-alone script)

The following stand-alone script displays some properties for a raster dataset.

import arcpy

# Create a Describe object from the raster dataset
#
desc = arcpy.Describe("C:/data/preston.img")

# Print some raster dataset properties
# 
print "Band Count:       %d" % desc.bandCount
print "Compression Type: %s" % desc.compressionType
print "Raster Format:    %s" % desc.format
