Python Gdal 栅格数据处理之图像重采样

一、功能

  将栅格数据重采样成与参考栅格图相同大小的分辨率。

二、代码

from osgeo import gdal
def resampling_img2(img_path, out_path, refer_img_path):
    """
    :param img_path:待重采样影像路径
    :param out_path：输出重采样影像路径
    :param refer_img_path：参考影像路径
    """
    gdal.AllRegister()
    dataset_re = gdal.Open(refer_img_path)
    tran_RefImg = dataset_re.GetGeoTransform()

    dataset = gdal.Open(img_path)
    x_size = dataset.RasterXSize
    y_size = dataset.RasterYSize
    array = dataset.ReadAsArray(0, 0, x_size, y_size)
    if len(array.shape) == 3:
        im_height, im_width, im_bands = array.shape
    else:
        im_bands, (im_height, im_width) = 1, arr
