arcpy批处理，使用栅格的范围裁剪矢量，并将裁剪后的矢量栅格化

应用场景：需要自动化地执行操作，将栅格的范围裁剪矢量，并将裁剪后的矢量栅格化。使用arcpy实现，代码如下：

import arcpy
arcpy.env.workspace = 'F:/DL_DATA/mass_buildings/test/sat'
rasters = arcpy.ListRasters("*", "tiff")
Output_Workspace = "F:/DL_DATA/mass_buildings/test/map_corr/ras/"
for ras in rasters:
    img = arcpy.Raster(ras)
    ext = img.extent 
    array = arcpy.Array()  
    array.add(ext.upperLeft)
    array.add(ext.upperRight)
    array.add(ext.lowerRight)
    array.add(ext.lowerLeft)
    polygon = arcpy.Polygon(array)
    fname = str(img)
    fname = fname.split('.')[0]
    clip_in_name = 'tmp/'+fname+'_clip_in.shp'
    clip_out_name = 'tmp/'+fname+'_clip_out.shp'
    label_out_name = 'tmp/'+fname[:8]+'_r'
    xy_tolerance = 0
    arcpy.CopyFeatures_management(polygon, clip_in_name)  
    arcpy.Clip_analysis("F:\DL_DATA\mass_buildings\massachusetts-buildings_corrected.shp", clip_in_name, clip_out_name, xy_tolerance)
    arcpy.env.extent = ext
    arcpy.PolygonToRaster_conversion(clip_out_name, 'aa',label_out_name,"CELL_CENTER","NONE",1)
    arcpy.RasterToOtherFormat_conversion(label_out_name, Output_Workspace, 'tiff')
    print fname+'Done'
