摘　　要：为了进一步提高“遥感图像处理实习”教学的质量,在增强学生对算法理解深度的同时简化编程难度,比较了各种开源遥感图像处理平台,选择基于GDAL进行遥感图像处理实习教学,设计了GDAL编程实习环节,主要包括遥感图像的输入输出、遥感图像波段组合、遥感图像投影转换和遥感图像几何纠正,并采取将ERDAS操作和GDAL编程教学实践相结合的方式实习。通过GDAL遥感实习教学应用实践,改变了遥感实习只强调操作流程和过于注重基础编程的实习状态,提高了实习教学的效率和效果。In order to improve the quality of remote sensing image processing practice teaching,and to enhance students’understanding of the algorithm while simplifying the difficulty of programming,GDAL is selected for teaching course by comparing several open source platforms.The practical teaching includes import/export of remote sensing images,band combination,reprojection and image merge,and take the way of combining ERDAS operation with GDAL programming teaching practice.Through the application practice of GDAL,the practice state that only emphasizes the operation process and the basic programming is changed.It concluded that GDAL is helpful for improving the practice efficiency and teaching effect.
