Virtual Construction Site

The most ambitious project in my ecosystem: an interactive, offline-first map of a linear railway construction site that combines official line geometry (PKP PLK / DB) with chainage calibrated against stations.

It handles markers with attachments and comments, storage yards with a materials calculator (ballast, sleepers, rails), per-kilometre notes and PL/DE layer separation, with export to KMZ/KML/GeoJSON. A native app (Tauri) with a local database — works fully offline.
