1. What is GLUES and the GLUES GDI?

GLUES (Global Assessment of Land Use Dynamics, Greenhouse Gas Emissions and Ecosystem Services) is the coordination project of the international research program 'Sustainable Land Management' of the German Ministry of Education and Research (BMBF). One of the outcomes of GLUES is the GLUES Geodata Infrastructure (GDI), which is the common data and service platform for the 'Sustainable Land Management' funding measure and related scientific projects. It is a network of Web services enabling standardized access to distributed geodata bases and analysis functions. For scientists it provides a communication and dissemination platform and a sustainable infrastructure for the documentation of scientific outcomes. Stakeholders get access to scientific results and support for land management decisions.

2. How can I use the GLUES GDI?

Members of the GLUES and the regional projects of the 'Sustainable Land Management' funding measure can publish and share data and metadata in the GDI. The provided data pool can be freely used within the 'Sustainable Land Management' funding measure but also by other interested scientists or stakeholders (please have a look at the conditions of use of the data you are interested in). The data catalog enables for searching data, services and applications. Visualization services and browser clients allow for interactive map views as well as time series and data provenance visualization. They can be freely used for outreach activities and stakeholder work. On request, we also provide the source code of the tools we developed for the GLUES GDI. Therewith you can integrate the Time4Maps client in your project website, for example.

3. Can I publish my own data or web services in the GLUES GDI?

For the partners of GLUES and the regional projects of the 'Sustainable Land Management' funding measure there are several possibilities to promote and publish own data in the GDI. The first and easiest step is to publish describing metadata in our catalog. Therefore you can get an login to the catalog and register your data by acquiring corresponding metadata (for the login please contact Carola Paetzold (carola.paetzold at If you are running an OGC CSW Catalog in your project we can also connect it to the GLUES Catalog and include it for external searches or harvesting. Data visualization and download services can also be registered in the catalog and integrated in the GDI. The implementation of such services depends on the specific requirements of your data and your project. In general, we prefer to use standardized OGC web services, but this is not an absolute condition. The GLUES-GDI team provides support and guidance documentation for metadata acquisition, data licensing, administration and setting up Web services in the GDI and corresponding authentication and authorization components. Please contact us!

4. I want to use a dataset: are there any usage restrictions or licenses to consider?

Most of the available data and documents can be freely used but require a citation of the authors. Detailed information about access restrictions, conditions of use and licensing of a particular dataset can be found in the corresponding metadata description in the catalog.

5. How can I use the applications developed for the GLUES GDI?

In the GLUES project, the GDI team has developed several Web clients and tools to visualize and explore scientific data of the Sustainable Land Management research program. The source code of the developed software is open source, so interested developers can use or modify source code, suggest further developments or implement his own extensions. Some of these open source projects are already available via the 52° North metadata management community in the 52° North GitHub Repository. These projects are licensed under The Apache Software License, Version 2.0. For our software projects that are currently not available in the Web, we provide the source code on request. Please visit our source code page for more information [information about source code usage].
