I have two shape files.

  1. Polygon shape file
  2. Point file contains some points.

Now i want to delete all the vertex of polygon shape file which are available in point file.

I am using ArcGIS(ArcEditor) platform.

Any ideas.

via GeoWizards

Polygon To Point (with Vertices option)

combine (merge) both point files

select duplicate points - delete them.

rebuild polygons with Point To Polygon

Advantage is the attributes from the original polygon are preserved through the new point file

+1. At first glance it seems this would not work, but Ianko wisely records the original order of the polygon points in Polygon To Point so that *Point To Polygon" can use this to reconnect the vertices in the correct sequence. –  whuber Feb 24 '11 at 15:21
    
Hence why I use Geo-wizards more often than ArcGIS Tools - Ianko tools work more efficiently and have had better results with his tools. Only Safe Software's FME gives more control over feature manipulation. –  Mapperz Feb 24 '11 at 15:50

Here's my initial thinking (I'm not sure to what extent ArcGIS can help with tools to do these steps):

  1. Create a point layer from the polygon vertices, with additional fields to track polygon and vertex order.
  2. Select from the above layer using the original point layer, and then delete those vertices.
  3. Recreate the new polygon layer.

your initial thinking is absolutely right but i was looking for some tool (if available) before building my own. –  iRfAn Feb 24 '11 at 13:58

Thanks for all those who has participated in this thread For those who are interested in the solution, i am using Manifold to do this. Here is thread http://www.georeference.org/forum/t108320#108357 An other reason for me start working in manifold.

This is result of procedure you have mentioned via GeoWizard.

Till now i have not deleted any point, just converted polygons to point and then point to polygons.

Hi irfan, could you add this to your question instead of as a separate answer? thanks! –  scw Feb 25 '11 at 8:33
