Geo-Services of T-Systems comprehend a wide variety of services such as:

• Geo-Consulting as a complete assistance or specialized consulting on Geodata-Provision or Geodata-Management
• Geo-Analyses and Geo-Processing
• Specification and implementation of Spatial Data Infrastructures (SDI) and GIS-Solutions for Business Processes, based on COTS and/or Open Source software  

Please find some more information about  projects in 2011 in the following paragraphs:

Evaluation of Digital Surface Models

Digital Surface Models (DSM) contain the heights of the bare earth as well as the three dimensional geometry of every feature on the ground like vegetation, buildings and bridges.

The height information in DSMs is important for radio link systems as well as mobile communication planning purposes.

During 2011 T-Systems evaluated such models based on various methods , e.g.:

• Laserscanning
• InSAR / IFSAR
• Matching of aerial photos
• Matching of satellite images
• Modelling of DSM based on 3d city models
• Synthetic DSM based on Landuse Data and street vectors

For the evaluation and final client recommendation on the provision and use of DSM data a geo specific point of view as well as the perspective of a radio communications network planner was taken into account.

Web Map Services for Cadastral Maps

WMS – WebMapServices – are a smart and easy way to visualize spatial information via the web.

Almost all German Federal Cadastral Offices of the 16 federal states offer the usage of well defined WMS for e.g. real  estate maps.

However, the technical, legal and financial conditions differ enormously. Customer driven a nation wide detailed investigation on the WMS in all federal states has been carried out.  

As a followup, the offered WMS are tested for their suitability, terms and conditions to fulfil the customer needs for an easy utilisation of the  WMS.

Market Investigation for Clutter Data

Digital Landuse Data (DLU) – also referred as Clutter Data – are important data in the field of telecommunication for the analysis and optimisation of complex mobile radio networks as the condition of the earth’s surface has a considerable influence to the coverage of a mobile radio network.

As landuse in the real world is changing permanently over time,  a regular update of the data representation,  is recommended at the latest every five years.

A wide variety of data is available at the geodata market, howeveronly a few datasets fit into the high quality requirements of mobile radio network planning.

And – this is an important factor as well – the price has to fit into the budgets.

A global market investigation was carried out for one of our customers.

Fibre to the Home

“Fibre to the x” – is a generic term for any broadband network architecture using optical fiber to replace all or part of the usual metal local loop used for last mile telecommunications.

The decision which areas will be covered by this technology depends on several factors with different prioritisation.

Among others, prominent roles play  the existing investment funds, the market share and the present market environment.

By the use of geospatial databases and GIS technology the different factors could be analysed and valuated successfully with the help of T-Systems.

Extensive Geo-Analyses, consulting concerning the use of GIS, optimisations of workflows and last but not least manpower led to an improved and accelerated overall planning process.

Spatial Analyses for the evaluation of the effect of business activities

By merging mobile and fixed networks to a common, spatially structured "Access network" more complex questions have to be answered in the business processes of telecom providers.

For the strategic development and operative control of such networks spatially related processes are required.

T-Systems established a business process for the geographical representation of scenarios of different radio communication services as well as the calculation of statistics for different administrative units.

Both, the coverage representations and the coverage statistics are stored in a central database and can be retrieved, analysed and represented together with other spatial data in Geographical Information Systems and web-applications.
