# 第1节 批量裁剪和批量重采样

* 说明：本人这是刚入门时学的 python和arcgis,由于快要毕业啦，不管好不好用，反正当初是实现了我要的功能，虽然现在回头看下确实比较烂，但是作为一种经验，也就放出来啦，毕业就转行了，这里就当做是一个留念吧。

## 1.利用arcgis的 ExtractByMask 工具进行批量的裁剪

```python
import arcpy
from arcpy.sa import *
path = "G:/GEE/spartinaWater"  # 工作路径
arcpy.env.workspace = path
rasters = arcpy.ListRasters("*0.tif", "tif")
arcpy.CheckOutExtension("Spatial")
inMaskDataAll = ["site4_20171231_20180931.tif"]
for inMaskData in inMaskDataAll: 由于我需要裁剪的不仅是 2 个掩模，所以用了两个 for 循环
    for inRaster in rasters:
        ractByMask = ExtractByMask(inRaster, inMaskData) # 裁剪的工具
        ractByMask.save(path+'/'+str(inMaskData)[:5]+'_'+inRaster[:25]+'.tif')
        print(inRaster)
```

## 2.下面是利用 Resample\_management 批量进行重采样的工具

```python
rasters = arcpy.ListRasters("site*", "tif")
for inRaster in rasters:
    arcpy.Resample_management(inRaster, path+'/'+inRaster[:-4]+'_re.tif', 
                              "20171002R2.tif", "CUBIC")
```
