大多数研究都是采用一种提取或分类方法进行的，对整体提取精度关注较少。采

Most researches are conducted using an extraction or classification method and pay less attention to the overall extraction accuracy. Although the use of high-resolution remote sensing images can improve the classification accuracy, the data coverage is small and the cost is high, which is not conducive to the extraction of large-scale feature information.

Most studies are conducted using an extraction or classification method, with less attention paid to the overall extraction accuracy. Although the use of high-resolution remote sensing images can improve classification accuracy, but the data coverage area is small, high cost, is not conducive to a wide range of material information extraction.
