Snap Polygon vertices to Point features

Question

I have a set of polygons drawn using an inaccurate GPS PDA. these polygons are sharing nodes.

after post-processing GPS data to get accurate coordinates i have a set of all the nodes, then i have to update the vertices of already drawn polygons. the relation between old and new vertices is based on the nearest point.

how could i modify polygon vertices in this case, using(arcengine , arcobjects) or just a GIS algorithm.

May be the whole process is not good enough so any suggestion is welcome.

Answer 1

You can use Snap (Editing) tool from ArcToolbox. It can be found in ArcToolbox\Editing\Snap.

Set inaccurate polygons as Input features and accurate points after post-processing as Snapping Environment. Also set reasonable Distance parameter for points.

Result of my testing the tool:

PS this tool is only available with ArcEditor and ArcInfo licenses.
