The NA1 Matrix provides links to ground-based instrumentation that is available to European planetary scientists, and which has the capability of supporting and complementing space missions. It not only contains the major observatories, but includes also medium- and small-size telescopes and instruments from professional facilities and amateurs that can fulfil niche requirements for the community. The matrix includes a tool to locate the facilities on the map.

This Splinter will give an overview of the NA1 Matrix for the public, demonstrating the usability and functionality of the system. The matrix is available online under http://europlanet-na1.oeaw.ac.at/matrix/.
