我有以下代码,它使用我需要的数据从 shp.file 创建我需要的 txt 文件。我有一个名为profiles 的文件夹,其中包含一些名为(profil1.shp、profil2.shp、profil3.shp 等)的形状文件。我想知道如何创建一个循环,以便脚本为每个文件创建一个具有相同名称的 txt 文件(例如,对于profil1.shp 创建profil1.txt,profil2.shp 创建profil2.txt 等等)。
import ogr, os, sys, osr
os.chdir('..\profiles')
file = open('profil1.txt', 'w')
driver = ogr.GetDriverByName('ESRI Shapefile')
datasource = driver.Open('profil1.shp', 0)
if datasource is None:
print 'Could not open file'
sys.exit(1)
layer = datasource.GetLayer()
feature = layer.GetNextFeature()
while feature:
id = feature.GetFieldAsString('ID')
Distanta = feature.GetFieldAsString('DIST')
Z = feature.GetFieldAsString('Z')
geom = feature.GetGeometryRef()
x = str(geom.GetX())
y = str(geom.GetY())
file.write(id + " " + Distanta + " " + "[X]:" + " " + x + ' ' + '[Y]:' + " " + y + " " + " " + "[Z]" + Z + " " + "\n")
feature.Destroy()
feature = layer.GetNextFeature()
datasource.Destroy()
file.close()
编辑:代码返回一个无法打开的文件。包含文件及其各自名称的文件夹的照片。可以安全地假设我做错了什么。
import ogr, os, sys, osr,os.path
os.chdir = ('C:\Users\Andrei\Desktop\profil3')
l = os.listdir('C:\Users\Andrei\Desktop\profil3')
for i in l:
if i.endswith('.shp'):
s1 = s.split('.')[0] + '.txt'
file = open(s1, 'w')
driver = ogr.GetDriverByName('ESRI Shapefile')
datasource = driver.Open(i, 0)
if datasource is None:
print 'Could not open file'
sys.exit(1)
layer = datasource.GetLayer()
feature = layer.GetNextFeature()
while feature:
id = feature.GetFieldAsString('ID')
Distanta = feature.GetFieldAsString('DIST')
Z = feature.GetFieldAsString('Z')
geom = feature.GetGeometryRef()
x = str(geom.GetX())
y = str(geom.GetY())
file.write(id + " " + Distanta + " " + "[X]:" + " " + x + ' ' + '[Y]:' + " " + y + " " + " " + "[Z]" + Z + " " + "\n")
feature.Destroy()
feature = layer.GetNextFeature()
datasource.Destroy()
file.close()
