The Ministry of Economic Affairs and Communications and the Land Board have unveiled an application that has overlaid three-dimensional building renders over the map of Estonia, allowing people to visualize most buildings in Estonia.
3D twin, developed by AS Datel, includes three-dimensional models of buildings throughout Estonia. The ground elevation model and 3D models of buildings used in 3D twin are created by the Land Board.
This digital tool is especially helpful for the real estate and construction sectors, but can also provide important information to, for example, a private individual purchasing a house. The new digital tool allows a look at what a building would look like in the existing environment, what restrictions should be considered when designing the building, and how shadows will affect the building.
The 3D tool is mainly meant for decision-making when it comes to environmental decisions. The 3D building renders have been created with the help of an automatic data processing program that uses data from Lidar pictures taken from the air. The application allows for data to be entered into regular context, displaying it along with other map layers from the Land Boards databases. In addition to buildings, the map application also shows a height map of Estonia, to go with aerial laser-scanning point clouds and modeled vegetation in some areas. There is also an option to apply for information from different registries about buildings.
While the Land Board's 3D application shows the external walls and detailed roof shapes of the objects, the 3D twin application allows for construction registry objects to be overlaid to the existing layer of buildings. The data will provide important information to the construction and real estate sectors. Both the Land Board's 3D application and the economic affairs ministry's 3D applications are still in their demo stages. There will be more options and data layers added in the future, helping to make better choices in spatial planning.
