Monitor of Settlement and Open Space Development (IOER Monitor)


The IOER Monitor is a service of the Leibniz Institute for Ecological Urban and Regional Development (IOER). It provides data and information for land cover and land use structure and change for the whole of Germany, particularly regarding sustainability.

About the Data Centre

The data research centre allows for accessing the data via a browser-based viewer, through geoservices and downloads.

Data is provided on an annual basis and available in high resolution on grids and administrative levels. The data sets provided are based on research results of the IOER. The metadata (data sheet) of the individual data sets give insights on used methods, calculation and used data. Among others, geotopographic data (ATKIS Basis-DLM), land cover data (LBM-DE), official building footprints (HU-DE) and house coordinates (HK-DE) as well as other geospatial data are used as input data.

The Research Data Centre provides access to the data via a map viewer with comprehensive tools and via geo services and downloads. As required the data can be obtained by interested scientists for Germany or for specified spatial delimitations and time periods. An overview of the more than 80 data sets including calculation methods, spatial and temporal reference and the corresponding export functions via geoservices is available at www.ioer-monitor.de/indikatoren.


The available data comprises indicators for the structure and change of settlement areas, open space, landscape, natural risks and energy: in particular urban sprawl, land take, soil sealing and ecosystem services.
