Spatial data often have defects that may include incomplete polygons, sleathers (non-uniform administrative boundaries), overlaps, having points that belong to more than one polygon, etc. I have a collection of spatial data in .shp format, which I wish to clean up. They include administrative boundaries and population/point data.
To clean the data, I'll have to first discover the defects. This process is hectic. I'm hoping that there are tools that I can use to automate this process.
I'm using GeoServer and PostGIS. I'm looking for tools that can I can use for the defect discovery.
