There are numerous applications of 3D city models: town planning, architecture, municipal asset management, security and defence, emergency evacuation planning, accident and catastrophy risk assessment, locationing services, information services, virtual reality, commercial visual effects and advertisments, telecommunications, visualizations, fly-through animations, and so on.
With Scontech applications you can produce a 3D model of buildings automatically by using airborne laser data and (optionally) images. An approximate model of little detail can be created even from a point cloud of less than 2 points on a square meter but the more dense the point cloud, the more accurate and detailed the 3D model. A complete result will be obtained by scanning the area from both air vessel (airplane or helicopter) and ground vehicle, matching the point clouds to each other.
Photo-realistic 3D City Model is a computerized model of a city. We use these models to give the user a picture of the world as it appears. In a photorealistic environment, the user may take a virtual city tour to find out where to find attractions.
In symbolic 3D City Model, we symbolize groups of features by colors or patterns and are stored in GIS database. In regular 2D GIS systems, symbolic data is often mapped onto the 2D layers showing land use, traffic or population. To create the third dimension, we add the object elevation as an attribute to each 2D form (building footprint or other multi-cornered object).
3D city models are used in a wide range of areas. In the navigation, they help to improve the recognition of the current position. In the map, they are indispensable in order to present the future appearance, for example, calculating gaps. Scontech provides digital and physical 3D city models, especially for your application based on your required area and level of detail of the model.
We have already completed more than 5000 km² 3D city models in the LOD2 and LOD3 with measured wall and roof colours for over 20 cities globally. Our 3D models are used for traditional applications such as urban planning, environmental modelling, navigation and location-based services.
