    Concluding remarks

    K. Lehnert: Supporting Science & Education with Geoinformatics

    Concluding Remarks

    • GI is necessary to support Geoscience research & education.

    • While the number of GI systems is growing, coordination and integration of systems is insufficient.

    • Open access to scientific data is fundamental.

    • Organizational and cultural challenges need to be addressed to make GI a real science infrastructure.

    • Scientists and educators need to actively participate in the development of GI.
