Network & Routing Analysis

Find the shortest path along a line network, or generate a service area showing everything reachable within a distance. Distance-based analysis along your network's actual geometry — not a driving-directions engine.

Two Kinds of Network Analysis

Shortest Path

Click a start and end point on your network — get the real shortest route along the actual line geometry and its exact distance.

Service Area

Click an origin and set a maximum distance — see everything on the network genuinely reachable within that range.

Frequently Asked Questions

Does this account for one-way streets or speed limits?

No — this is distance-based shortest path and service area analysis along your network's actual geometry, not a driving-directions engine. One-way restrictions, speed limits, and turn restrictions aren't modeled.

My network has small gaps between lines that should connect — what happens?

The snap tolerance setting merges nearby line endpoints (within the distance you set) into a single connected point before analysis, so small digitizing gaps don't break connectivity. Increase it if two segments that should connect aren't being treated as connected.

What file formats can I upload as a network?

GeoJSON, Shapefile (zipped), GeoPackage, KML/KMZ, or a spreadsheet with coordinates — any line/polyline layer representing roads, paths, or drainage.

Can I export the results?

Yes — the route or reachable network exports as GeoJSON, Shapefile, or KML.

Need real routing with turn restrictions, speed, or time-based analysis? Our team can build that on top of your actual network data.
