python - GDALWarp 返回 NULL 且未设置错误

Question

GDALWarpDestName 返回 NULL 且未设置错误

我正在尝试将几个栅格(tif 格式)重新采样为粗分辨率，而 gdalwarp 运行结果为空

def resam(inDs):
 gdal.Open(inDs)
 (shotname,extension) = os.path.splitext(os.path.basename(inDs)) # get the filename and extension
 outDs = shotname+'_232_ave'+extension      #result tif of resample
 gdal.Warp(outDs, inDs,
              format = 'GTiff',
              xRes = 232.03572204, yRes = 232.03572204,
              resampleAlg = gdal.GRA_Average)
if __name__ == '__main__':
files = os.listdir(path)

for file in files:
        inDs = file # input tif
        resam(inDs)

预期结果应该是将当前路径目录中的所有文件重新采样为 xRes*yRes 分辨率，即 232.03572204。

“GDALWarpDestName returned NULL without set an error”可能是由错误或无效的输入引起的，因此请检查您的 inD。
