Cartography

Mapping information is strategic for the deployment or management of a network. At ATDI we have accumulated a sizeable catalogue of existing worldwide cartographic data. That infomation is stored on ATDI's large scale servers.

The ATDI mapping department can produce or convert any type of data including digital reference mapping (maps, satellite photos, aerial images, etc.), land occupancy or Digital Elevation Models (DEM).




System integration & management solutions
ATDI has developed complete networking, sharing and management solutions for mapping information. Large volumes of data in different coordinate reference systems need to be manipulated to process geographic information.
Intranet and Internet solutions can make all these geographic data easily accessible to users in the company, performing complex calculations whenever they are necessary.

Acquiring data

ATDI's expert cartographers can help you acquire and validate raw data. Once ATDI has confirmed the quality of the data, its acquisition is swift. The aerial photos, ground control points, satellite images and maps are then processed and formatted for the customers.

ATDI has developed a network of local cartographic partners, and is official dealer of the French National Geographic Institute (IGN), and of the U.K. Ordnance Survey.

Sourcing of existing data

ATDI's skilled professionals have accrued extensive experience in the sourcing of existing cartographic data. Using our partnerships with industry leaders and government agencies around the world, we can identify quickly existing data sets and ensure their quality.

Production

In addition to providing the software used to create the digital images and layers needed for audio planning, ATDI also has impressive production capabilities. Our cartographic department manages a large high resolution laboratory, with extensive production capabilities in digital stereo restitution and high resolution digitizing.
ATDI / SRTM. The revolution in medium resolution cartography


SRTM, Shuttle Radar Topography Mission
SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA). The Shuttle Radar Topography Mission (SRTM) obtained 1 arc second accurate data to generate an almost complete digital topographic database of Earth at 3 arc seconds resolution. The post-processing done by ATDI generates 90m (and even 50m) DTMs, fitting the following needs in terms of cartography:

  • Large areas covered (Regional, national and international scale)

  • Reduced cost and delivery times

  • The technical specifications are homogeneous and clearly defined over the Area Of Interest


High and Homogeneous Quality Datas
By using a unique acquisition mode all over the Earth, a single technical specification can be defined.

  • Absolute vertical accuracy : 16 m

  • Relative vertical accuracy : 10 m

  • Absolute planimetric accuracy : 60 m

  • Relative planimetric accuracy : 45 m

  • Sampling : 3 arc seconds


Low cost / High quality
The post-processing handled by ATDI (ICS Map Server software) is therefore time effective:

  • Tiling and geoconversion

  • Local treatment over coastal areas


Technical specifications of the ATDI/SRTM product:

  • Planimetric resolution : 90 m interpolable up to 50 m.

  • Altimetric resolution : 16 m.

  • Projection over a metric grid

Off-the-shelf catalogue
ATDI's software tools work using cartographic information in 2D and 3D. ATDI always offers its customer a complete solution including the software and the relevant cartography:

  • the topography of the terrain (Digital Elevation Model, also known as Digital Terrain Model), used to perform calculations,

  • an image (Digitised Maps, Satellite Views or Aerial Pictures), used to display the coverage results in an understandable way.


The ATDI mapping department can also produce or convert any type of data.
