I currently work with large sums of lines data. I am editing them using different GIS software. I've realized that I can detect node problems in arcmap10.1.

I would like to know if it's possible to programmatically snap the detected dangling nodes and other issues. I have Microsoft Visual Studio 2010 (C#) installed with ArcObjects, but I am struggling with the code to develop such a stand-alone program.

This would make my work so much easier in the future as I have to manually snap these detected dangling nodes.

  • Why are you writing a program if you are looking for and correcting topological issues? You don't say what license level you have but if you have ArcEditor license why not use the Topology rules to identify and correct your data? If you do not know what I am talking about then have a look at the help file. Without more description sounds like you are re-inventing the wheel? – Hornbydd May 29 '14 at 9:17

I would suggest the Integrate ArcGIS tool instead if there are only slight imperfections in the data.

  • Be careful what tolerance you use, I've seen Integrate fix weeks worth of manual work and also completely destroy features. keep a backup copy of your data before running integrate and visually check your results are suitable before investing more time in the data. – Michael Stimson May 29 '14 at 22:37
