The Infrastructure Atlas (ISA) as part of the Gigabit Basic Book is a central information and planning tool for broadband expansion in Germany. It provides an overview for the initial planning stages of broadband expansion projects and serves to prepare specific shared use claims in the advanced planning process.

The ISA contains the infrastructure data of several 1,000 network operators and makes this available to authorized companies, but also to the federal government, federal states, districts and municipalities in the context of broadband expansion. The geodata, for example the route of fiber optic cables, is displayed on digital maps in the ISA.

You can view the infrastructure atlas if you

• are involved in a specific project to expand public supply networks or
• require access for general planning and funding purposes.

You must also belong to one of the following groups:

• Owners or operators of public supply networks and their contractors in the context of specific expansion projects on public supply networks. This may include, for example, telecommunications providers, but also energy and water suppliers.
• Regional authorities (federal, state, district and local authorities) and their contractors in the context of general planning and funding purposes
• the Federal Ministry of Digital and Transport (BMDV)
• other parties involved in the expansion of public supply networks

Access is only possible on request. It is limited in time and restricted to the area required for planning.
