Polyline to Polygon

[ChrisSlinko]

I have parcel data that is polyline shapefile and I would like to convert it to a polygon.  I've tryed ETGeoWizard Polyline to polgon and that did not work.  I've put in a request to have another shapefile sent to me but that is all the town has.  The problem is the town did not digitize the parcel's as individual polygons but as random lines.  Can anyone offer me any suggestions?  I'm using ArcView 10.1.
Any help would be greatly appreciated.  Thanks.

Hola Chris,

With only having a Basic license level of ArcMap, you are limited to tools within ArcMap to perform this process. I would suggest looking at options like you are with, ETWizard, Xtools, or maybe some ArcScripts. In regard to the issue though you seem to be encountering, I would suggest maybe importing the shapefiles into a File Geodatabase and then running the Check & Repair Geometry on the parcels feature class. Then I would run them through one of software or items suggested (ETWizard, Xtools, or maybe some ArcScripts). Good Luck!!
Gracias, Chris!

I hope the lines aren't totally random.  🙂 As Juan suggested you want to make sure you are dealing with good geometry.   I'll assume your problem is the lines have gaps that prevent polygons from being formed, and these are too large for the default tolerance to fix.    ET Geowizards has several line tools and clean polygon tools you could use to close those gaps as well as the option to adjust your tolerance.  I suggest you start reading the Build polygon, clean polyline layer and dangling nodes notes and then follow the recommendations therein.  The gaps may be such that you have to do some manual fixing, but the Export Nodes wizard can at least point you to places where you have gaps.

Once your polygons are built then you have to get the attributes into the polygons.  I'm not sure from your text where they are stored but check out a spatial join of either points or the lines to the new polys.

First you need to clean up the line work making sure the polylines close as John mentioned.  Sloppy line work is a curse for this kind of thing.

Then in ArcView try this:

You can form polygons from as many closed line shapes and from as many layers as you want in one go just by copying them all and merging them then running the procedure I outlined in the numerous previous posts on the subject using the "Auto-Complete Polygon" Task.  No need to use any out side tools; it was just never documented in 9.x, but also works in 10 and I'm not sure if it was documented there either.

you can use Feature to Polygon in ArcToolBox to convert polylines to polygon
