遥感图像的裁剪有多种方法,比如按照指定的shapefile图形裁剪,即Arcgis工具箱中的Clip工具。Clip工具在Arcgis工具箱中有两个:一个在分析工具(Analysis Tools->Extract->clip里面),和主要是针对矢量图形的裁剪,而不针对栅格数据;另外一个是在Data Management Tools->Raster->Raster Prossesing->Clip,这个是采用矢量图形或者栅格图形的范围对待裁剪图像进行指定区域的裁剪。
1.工具介绍
Arcgis中还有一个工具也可以实现对遥感图像的裁剪,这工具就是Split Raster,该工具位于:
Data Management Tools->Raster->Raster Prossesing->Split Raster路径下。
我们打开该工具参数设置窗口,参数的具体解释如下图:
英文参数解释如下:
Input Raster:The input raster dataset to be split into tiles.
Output Folder:The output folder, where the tiles will be created.
Output Base Name:The prefix for each file name. The tile number is then appended to complete the file name, which starts with 0.
By default, the prefix is the same name as the input raster.
Split Method:The tiling method to be used when splitting the raster dataset. It will determine the size and number of tiles for each output dataset.
