Local planning inputs

Local processing without upload or storage.32KiB per field,1MiB complete result,one-second Worker deadline. Editing cancels work and clears old diagrams/exports. Edit text rows for keyboard positioning/reordering. No external map tiles or device location.

Diagram and data

Edit inputs and build. All previews are generated locally.

Processing model and limits

GPX track segments only, ≤2000points/200segments; longitude[-180,180); reject segments crossing the antimeridian (split at the dateline first); reject DTD/entities/stylesheet, unsupported namespaces/extensions and malformed XML. Haversine sphere radius6371000m, horizontal distance, positive/negative elevation differences; never bridge segments. Duration sums consecutive timestamped legs; report incomplete timing/elevation. Not GPS accuracy or geodesic certification. Local data only. Each field ≤32 KiB; ≤200 records, ≤80 graph nodes/300 edges, JSON depth30/nodes10000, ≤2000 coordinates. Complete result ≤1 MiB; diagram ≤8 million pixels and16384px per side. Edit text to move/reorder items; build again. SVG is a readable model, not an externally rendered image.

How to use this tool

Edit the labeled text fields, build, inspect the diagram and data, then copy or download JSON/SVG. Text editing provides the keyboard alternative to dragging.
