在做三维场景的时候,经常会涉及多种不同DEM数据格式之间的转换,如ASCII、GRID、IMG、TIFF等等,遇到大数据量时,我们就需要批量转换功能了。
下面使用python脚本来实现批量转换,把f:\\test文件夹下的*.grd栅格文件转换为*.TIFF文件并存于其下的TIFF子文件夹中:
- #
Import system modules - import
sys, string, os -
-
dir
= 'F:\\test' -
- #
Import arcpy module - import
arcpy -
-
files
= os.listdir(dir) - for
f infiles: -
os.path.splitext(f)[ 1]== '.grd': -
Script arguments... -
Input_raster_file = dir + os.sep + f -
-
Local variables... -
Output_data_type = -
Raster_Format = -
Output_Workspace = -
-
=============== file name process ====================== -
basename = os.path.splitext(f)[ -
Output_raster = Output_Workspace + os.sep + basename + -
-
os.path.exists(Output_raster) False:== -
Input_raster_file -
Process: Raster To Other Format (multiple)... -
arcpy.RasterToOtherFormat_conversion(Input_raster_file, -
Output_Workspace, Raster_Format) -
-
Output_raster
# Import system modules import sys, string, os dir = 'F:\\test' # Import arcpy module import arcpy files = os.listdir(dir) for f in files: if os.path.splitext(f)[1] == '.grd': # Script arguments... Input_raster_file = dir + os.sep + f # Local variables... Output_data_type = "FLOAT" Raster_Format = "TIFF" Output_Workspace = "f:\\test\\TIFF" # =============== file name process ====================== basename = os.path.splitext(f)[0]; Output_raster = Output_Workspace + os.sep + basename + ".tif"; if os.path.exists(Output_raster) == False: print Input_raster_file # Process: Raster To Other Format (multiple)... arcpy.RasterToOtherFormat_conversion(Input_raster_file,Output_Workspace, Raster_Format) print Output_raster
