I am working on creating a project boundary for a specific area. To do this I merged several data sets including roads,rivers & railroads (polylines) and lakes, civil townships & congressional townships, (polygons converted to polylines) into a single polyline feature class. I then split the polylines at every intersect in the data. I then created a subset of the data using only the nearest features to the project area to create a boundary.
My problem is my data has some issues with overlap. In some areas the civil townships are coincident with bodies of water or roads and the polyline for both types of feature are overlapping (or close to overlapping) in my subset of the data. I would like to clean up the data so there is only 1 line for each section of the boundary and duplicate boundary lines are deleted. after I get a clean polyline feature I was planning and using the feature to polygon tool to create the the final boundary.
Is there a simple method of cleaning up this data? I already have used topology rules to clean up a few thing such as dangles, but I couldn't really find a rule that applied to my situation.
any advice would be appreciated.
