Shapefile Repair Tool 1.0
I’ve posted before on two free Windows apps for fixing corrupt shapefiles, Shape Checker and Shapefile Repair Tool. PerryGeo describes a third option: use the command-line tool ogr2ogr to re-write the shapefile under a new name, hopefully with the corrupt parts fixed. From that post, and from its comments, you would use the following command operation:
- Run the Repair Geometry tool in ArcToolbox Data Management Tools Features. After running the Repair Geometry tool, go back and run Check Geometry again to make sure that all corrupt features have been removed. Rerun the Check Geometry and Repair Geometry tools as many times as required. Export the data to a geodatabase, and copy it back to.

ogr2ogr is available as part of the installable FWTools package, but can also be installed using the OSGeo4W program covered earlier covered earlier on this blog.

Don’t like command-line operations? The free ogr2ogr GUI ogr2gui can do the same operation, with a little extra effort:
1. Select the corrupt shapefile as the source, and set the Target type as “Shapefile”:
2. Add in the “-skipfailures” switch by typing in the line command box below:
3. Click “Execute”, and you’re done. Unfortunately, I didn’t have a corrupt shapefile to test it on, but worked fine on a good shapefile. If you’ve got a corrupt shapefile, let me know if it worked for you.
Keep in mind that this isn’t a guaranteed fix. PerryGeo’s post quotes a 90% success rate, and the comments to the post note that sometimes in a corrupt shapefile, the fixed file may not have the attributes correctly linked to the matching shapes. YMMV.
