GPX Editor

This tool accepts GPX data and enables editing of track points, routes, and metadata to improve accuracy, interoperability, and shareability. It serves hikers, cyclists, runners, GIS analysts, and GIS technicians who need to repair corrupted files, reorder waypoints, trim long tracks, or adjust timestamps before publishing to communities or analysis pipelines.
Under the hood it parses GPX XML, validates against GPX versions, and applies edits deterministically. Required operations include reordering or splitting tracks, updating waypoint attributes (name, description, elevation), and normalizing times to ISO 8601. Optional operations include smoothing paths, filtering out outliers, and exporting to alternative formats. Non-destructive by default; maintains a change log for reproducibility.
Core features provide distance and ascent calculations using haversine and elevation delta, integrity checks for missing coordinates, and conflict resolution when multiple segments share timestamps. The tool preserves original data lineage, attaching a summary of changes and the before/after metadata to assist reproducibility.
Use cases span field data collection, post-processing of outdoor trips, and data cleaning for dashboards or mapping projects. Unique differentiators are strict adherence to GPX structure, non-destructive edits by default, and optional batch processing for large files. Output GPX remains valid for standard GIS tools.
