说明：  针对地理学、地理信息系统、遥感技术与应用等专业的技术人员，在使用ArcGIS软件绘图时，可以采用Python 中Arcpy 模块，实现批量处理。 针对栅格数据即遥感影像，在对图像进行分析时，如变化检测，土地覆盖类型提取等。这些都需要依据光谱特征对图像进行分类，并对分类后的结果进行标记。(For the technical personnel of geography, GIS, remote sensing technology and application, arcpy module in Python can be used to realize batch processing when drawing with ArcGIS software. For raster data, that is, remote sensing image, in the analysis of the image, such as change detection, land cover type extraction and so on. All of these need to classify the image according to the spectral characteristics and label the classified results.)
