QH Lạng Sơn

QH Lạng Sơn is a Chrome extension for quickly viewing Lang Son's 2030 land use and construction planning. Users can check whether a specific land plot falls under planning by searching with sheet and plot numbers, entering coordinates, or clicking directly on the map. The extension also lets you pin plot information for later review and sync pinned data across devices.

Data is sourced from official planning portals and provided for reference only; the app does not represent any government agency and has no legal authority. QH Lạng Sơn streamlines parcel lookup and planning visibility for residents, surveyors, planners, and real estate professionals who need fast access to local planning maps and plot details.
