I have recently taken on a piece of work that involves the reshaping of a large number of polygons that represent planning applications. The polygons are often based around the extents of a properties and have been drawn by various people over a number of years to varying degrees of accuracy, often with missing or additional vertices to the vector base map they are based upon.
I need to reshape these so they align perfectly to the geometry of the vector base map and do not have gaps and overlaps between them. There are often multiple polygons sat on top of each other and thus far it has been the tedious process of selecting them individually and adding removing vertices in order to align them to the geometry below.
I am a somewhat novice ArcGIS user and am wondering if there is a more efficient way to carry out this process, retracing the boundaries in some cases is working but often as there are multiple polygons of only slightly different shapes sat on top of each other I am having a hard time tracing the base map below without having the trace tool pic up extra vertices I do not wish to be included or veering off the base laer I want my polygons to match.
If anyone has any advice on how to better carry out this task it would be much appreciated.
