3D Buildings

3D Buildings

• New developments in urban planning, urban
  landscape, real estate management, and so on,
  call for new demands for the 3D Object Model.
  The building models are the most important in the
  3D object model. With the development of 3D data
  acquisition, the visualization aspect often is
  detail considered.
• Sometimes, there is no suitable 3D data or the
  auto-reconstruct process is not perfect to depict
  sufficient details, for instance, the balcony
  and a small tower in buildings can not be auto-
  reconstructed. The operator has to do this by
  himself. The 3D data can be used to create two
  basic categories of objects
• point, line, and surface objects coinciding with
  a ground surface such as streets, roads, etc.
• volume objects that stick out the ground
  (buildings, towers, and so on ).

SATPALDAs 3D building models can have these two
categories. These models are derived
photogrammetrically from high-resolution
satellite and aerial imagery designed to support
developers, architects, networks, and urban
planners. Its about giving shape, height, and
elevation of the buildings based on the latest
remote sensing imagery. Height Mean Sea Level
(MSL) Above Ground Level (AGL)
Accuracy Absolute 1m (LE90) Delivery

• Applications
• These datasets are used for many simulations such
  as telecommunication, asset planning, analysis
• of the view
• Giving 3D tours in the real estate sector
• One can have a site layout
• Used in telecommunication projects
• Used in aviation where the height of buildings
  inside and near the airport is required
• Used in gaming and various simulators
• Used to measure the volume, and surface area of
  objects
• Incorporate new buildings into the existing urban
  model
• Edit the properties as per the modification
• Aesthetic assessment of an existing neighborhoods
