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 modulesimport sys, string, osdir = 'F:\\test'# Import arcpy moduleimport arcpyfiles = 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
