I'm writing a Python code to read the points in a polygon shapefile and save them to a point shapefile.
I'm not sure about my approach so if you have a better idea (even if it is totally different from mine) please let me know.
So first I made a text file and stored the points' (x,y) in that .txt file. then I tried to make a point shapefile from the text file but it gave an error.
Here is the code (just the last part):
creat point shape-file from text file
import fileinput
import string
import os
env.overwriteOutput=True
outpath="C:/roadpl"
newfc="newpoint.shp"
arcpy.CreateFeatureclass_management(outpath, newfc, "Point")
infile="C:/roadpl/roadL5.txt"
cursor=arcpy.da.InsertCursor(newfc, ["SHAPE@"])
array=arcpy.Array()
for line in fileinput.input(infile):
point.X, point.Y = line.split()
line_array.add(point)
cursor.insertRow([arcpy.Point(array)])
fileinput.close()
del cursor
Here is the error:
Traceback (most recent call last):
File "C:\roadpl\P_Code_L5", line 49, in <module>
point.X, point.Y = line.split()
File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\arcobjects\_base.py", line 87, in _set
return setattr(self._arc_object, attr_name, cval(val))
RuntimeError: Point: Input value is not numeric
I made the input file (.txt file) from a polygon shapefile using:
cur = arcpy.SearchCursor("C:/roadpl/L5P.shp", ["SHAPE@"])
f=open("C:/roadpl/roadL5.txt", "w")
for row in cur:
geom = row.shape
row = geom.getPart()
for part in row:
for point in part:
print >>f, (point.X, point.Y)
f.close()
