Routing along your own network data — not a public road API, your actual survey lines, trail network, or drainage layer — needs real graph construction under the hood: every line segment connected into a proper network, with small digitizing gaps handled so the routing doesn't silently break at a gap that should have been a junction. Network Analysis builds that graph automatically from an uploaded line layer.

What you need before you start

Any line/polyline layer representing a connected network — GeoJSON, Shapefile (zipped), GeoPackage, KML/KMZ, or a spreadsheet with coordinates. Roads, footpaths, drainage channels, or any linear network works the same way.

Real-world line data almost never connects perfectly. Small digitizing gaps between segments that should join are extremely common. The snap tolerance setting merges nearby endpoints within the distance you set before building the graph, so those gaps don't silently break routing. If two segments that should connect aren't being treated as connected, raise the tolerance.

Two kinds of analysis

  1. Shortest Path

    Click a start and end point on the map. Get the real shortest route along your network's actual geometry, and its exact distance — not a straight-line estimate.

  2. Service Area

    Click an origin and set a maximum distance. See everything on the network genuinely reachable within that range — useful for coverage studies and facility planning.

What this doesn't do

This is distance-based analysis along your network's real geometry — not a driving-directions engine. One-way restrictions, speed limits, and turn restrictions aren't modeled. If you need real routing with those factors built in on top of your own network data, that's a service we can build.

Exporting your results

Both the shortest-path route and the service-area's reachable network export as GeoJSON, Shapefile, or KML — ready to bring into a report or another GIS workflow.
