KMZ to GPX Converter

Purpose & problem: This tool converts KMZ geodata packages into GPX, enabling reuse in GPS devices, GIS software, and mobile mapping apps. It accepts KMZ inputs (zip archives containing KML) and outputs GPX with equivalent geographic entities. Core logic: unzip KMZ, locate KML, parse Points as GPX waypoints, convert LineString/Track segments into GPX tracks, and preserve coordinates, altitude where available, and timestamps when present. Benefits include data integrity, broad compatibility, and support for field-to-desk workflows. Target users include field technicians, trail mappers, surveyors, and developers integrating GPS data into analysis pipelines. Unique value lies in automatic feature mapping, minimal attribute loss, and batch processing capability for project-scale data. Core features include: file-based input, KMZ unzip, KML-to-GPX mapping, preservation of lon/lat/elevation and time, support for tracks and routes, optional version selection, and per-file output packaging for downstream workflows. Use cases include converting expedition routes for GPX viewers, exporting survey points to mobile collectors, and preparing mapping data for open-source GIS communities.
