MAPPING ALL OF VIETNAM


The Vietnam nationwide coverage created by Visicom includes:
  • 331210 sq.km of Regional countrywide model;
  • 3D models of 74 Vietnam cities;
  • Population maps of all Vietnam;
  • Population maps of all 74 cities;
  • Geo-database with semantic infrastructure information: 314 532 POIs.
In order to complete the project and ensure the required accuracy it was bought over 95 stereo-pairs of satellite imageries with 0.3-0.5 m/pixel resolution. Accurate and reliable spatial orientation of them was made based on the set of 200 GCPs (Ground Control Points).

3D CITIES - KEY FIGURES:

  • Total area - 5053 sq.km;
  • Buildings quantity: 12,000,000;
  • Roads network: 75 000 km;
  • 2 m resolution of DTM, DSM, Clutter, Clutter heights;
  • 2-3 m accuracy in all parameters.
The vegetation layers and their heights were captured using the recognition algorithms which are based on the artificial intelligence (AI), in particular neutral networks. 

The geo-database might be used further across multiple industries where relevant and up-to-date information regarding the built-up territory is needed:
  • Urban planning environmental management;
  • Transportation;
  • Risk mitigation; 
  • Emergency response;
  • Infrastructure rollout, etc. 

DATA FORMATS

The data are compatible with any RF modeling tool including: Atoll/Mentum Planet/Asset/ICS Telecom/ESRI ArcGis  etc.

The data samples are available for free  https://visicomdata.com/samples?lang=en#vietnam
