About the GREN Global Map Working Group

The GREN Global Map working group of volunteers from the R&E Networking community, working on data formats and applications facilitating collaborative, interactive network maps.

The initial criteria for the success of the delivered visualisation product are:

A dynamic/interactive map (zoomable with selectable layers and sections), which also supports printed versions;
The ability to show intra- and inter-NREN nodes and connections, including some meta information (e.g. link speed);
The ability to show connected institutions and major science infrastructure and instruments;
A model where data is maintained by individual (N)REN operators and collected automatically, in a common format, in order to reduce update overhead and keep the map continuously up to date; and
Achieving a critical mass of participation.
