A map for looking at land in Korea — cadastral parcels, zoning, sunlight hours and street view on one 3D VWorld map. For land surveys and solar site hunting.
- Click parcels, get the area. Every parcel you click is added to a list with lot number, land category, area (m²) and zone — with a running total in m² and pyeong.
- See the rules that actually apply. Zones are looked up per parcel from the official land-use plan, and the one that really restricts the land is shown first.
- Sunlight hours for solar sites. Average daily sunlight for each selected parcel, taking the surrounding mountains and terrain into account — the same method solar site-analysis tools use.
- Look without driving there. Street view opens side by side with the map and searches nearby roads, even for rural parcels with no road of their own.
- Real terrain in 3D. Slopes and ridgelines on an elevation-aware 3D map.
- VWorld 3D map; search by lot address, road address or place; recent searches; my location
- Cadastral lot numbers and boundaries as separate toggles; right-click for lot number, elevation and full address
- Selected-parcel list with totals; save and restore parcel groups
- Zoning layers: urban, management, agricultural/forest, nature conservation, farmland promotion, development promotion
- Solar sunlight analysis (12-month average, clear-sky theoretical hours)
- Distance and slope between two points, spot elevation
- Satellite map + street view split screen that follows your clicks
