Map data

Map data

As a leader on the high-resolution market, Viet Hai has become a major supplier of map data dedicated to RF planning and network optimization for mobile operators, equipment vendors and planning tool providers. Our products address all wireless technologies


Map data for Country Coverage

These products are dedicated to large coverage areas and contain 4 layers:

GeoImage_25mCountryOrthoimage: source of information used to create the database
Vector: different types of linear infrastructures and networks
DTM: height of the earth surface
Clutter: different types of land use.

We typically suggest 4 different resolutions, depending on the level of detail accuracy and details required: 100m – 50m – 25m and 20m


Map data for City Coverage

These products are used in city environments and contain 4 layers:

GeoImage_5mCityOrthoimage: Source of information used to create the database.
Vector: different types of linear infrastructures and networks.
DTM: height of the earth surface.
Clutter: different types of land use.

Products are provided in 3 resolutions, depending on the level of accuracy required: 20m – 10m and 5m


Map data – 3D Buildings

GeoImage_3Dbuilding

A Critical Input for Planning LTE Overlays. High-resolution 3D digital maps provide the world model for RF planning and optimization in populated urban centers. If you are considering multi-floor receiver heights and small-cell planning, this is the digital map datafor your project. These products are dedicated to city center coverage and contain 5 layers:

GeoImage_3Dbuilding

Orthoimage: source of information used to create the database
Vector: different types of linear infrastructures and networks
DTM: height of the earth surface
Clutter: different types of land use.

DHM: height of the building.

This product is typically provided in 2m and 5m resolutions.


Population Maps

GeoImage_PopulationThis product is an additional layer, which can be useful for network planning and optimization. This map allows you to have a realistic estimation of the population and the way it is dispersed inside a city or a country.

We have developed a specific method using population figures (issued by legal entities) and geodata. Our mathematic mean square methodology associates a population density to each clutter class, to recreate an additional layer called “population map”.

 

 

 

 


Ubanism

This product is used in urban planning, or by entities that require very realistic 3D models such as as municipalities, government agencies, etc.

GEOurba is based on the specifications of GEOmetris 3D Buildings 2m. The only difference is that we insert the real textures of each building. These textures can be extracted from aerial/satellite imagery or from street maps.
