ArcGIS Desktop Basic 10.1 with Spatial Analyst and 3D Analyst
I have multiple neighboring polygons which I unionize. On occasion the result has slivers where the multiple polygons meet. I have been searching on the simplest way to get rid of these slivers but it seems like all tools work on features or feature classes. The result is a IPolygon element which I am drawing to the screen so don’t use the IFeature or IFeatureClass objects.
The before and after looks like this:
The end result should be one complete polygon with no slivers. The dimensions of the polygons are in 2 to 3 miles and the slivers are very tiny. I've zoomed in very close so estimate the slivers to be about ~5FT which is negligible for my purposes.
To unionize I have tried:
ITopologicalOperator4.Simplify seems only ensures the topology is correct Integrate_management and RepairGeometry_management require feature classes Eliminate requires Desktop Advanced which I don't have
My goal is to unionize the collection of IPolygon objects with no slivers?
