使用python从shapefile中删除记录

完全按照你描述的程序对我来说似乎很好。我首先打开一个形状文件:

>>> e = shapefile.Editor('example')

此文件有三种形状:

>>> e.shapes()
[<shapefile._Shape instance at 0x7f6cb5f67dd0>, <shapefile._Shape instance at 0x7f6cb5f67f38>, <shapefile._Shape instance at 0x7f6cb5f6e050>]

我删除第一个形状并保存文件:

>>> e.delete(0)
>>> e.save('example')

现在我重新打开文件:

>>>e=形状文件。编辑器(“示例”)

我可以看到它现在只有两种形状:

>>> e.shapes()
[<shapefile._Shape instance at 0x7f6cb5f6e518>, <shapefile._Shape instance at 0x7f6cb5f6e560>]

我不熟悉 pyshp 但这可以通过使用 ogr ,它允许使用矢量数据,并使 gdal 图书馆

from osgeo import ogr

fn = r"file.shp"  # The path of your shapefile
ds = ogr.Open(fn, True)  # True allows to edit the shapefile
lyr = ds.GetLayer()

print("Features before: {}".format(lyr.GetFeatureCount()))
lyr.DeleteFeature(0)  # Deletes the first feature in the Layer

# Repack and recompute extent
# This is not mandatory but it organizes the FID's (so they start at 0 again and not 1)
# and recalculates the spatial extent.
ds.ExecuteSQL('REPACK ' + lyr.GetName())
ds.ExecuteSQL('RECOMPUTE EXTENT ON ' + lyr.GetName())

print("Features after: {}".format(lyr.GetFeatureCount()))

del ds
