What is Active Topology?

Active Topology™ map editing in Maptitude mapping software automatically maintains the relationships between connected map features as you edit, helping roads, boundaries, and areas stay connected, aligned, and topologically correct. Move an intersection and the connected streets move with it. Edit a shared boundary and the geography remains consistent. Active Topology helps prevent the gaps, overlaps, slivers, dangling lines, and open polygons that can compromise GIS analysis.

The result is cleaner map data with less manual repair. Roads stay connected at intersections, shared boundaries stay aligned, and area features remain properly closed. For users editing streets, territories, service areas, ZIP Code-based geography, parcels, districts, or other connected map layers, Active Topology turns map editing from a fragile drawing task into a data-integrity workflow.
