Xem vị trí sổ hồng is a free Android application developed by Nhà Đất Hoàng Sơn. It helps users to locate real estate properties using VN-2000 coordinates on land certificates. The app shows the position of land on Google Maps, and draws a diagram of the land plot on the map. Users can enter the coordinates or scan the coordinates from a photo, and the system recognizes the coordinates on the land certificate, saving time.

The app is designed to be user-friendly and intuitive, providing an easy way to locate real estate properties. It is a useful tool for those who need to find the location of a property quickly and accurately. However, the app is only available in Vietnamese, which may limit its accessibility to non-Vietnamese speakers.
