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 ArcGIS Engine , ArcObjects or just ArcGIS Desktop?

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: result1

This tool is only available with ArcEditor and ArcInfo licenses.
