Permafrost-related research data - their accessibility, visualization, and publication using GIS and WebGIS technology

Antonie.Haas [ at ]


Permafrost regions are highly sensitive to climate changes. The monitoring of key variables and identification of relevant-processes is of topmost importance in these environments. ESA DUE GlobPermafrost ( provides a remote sensing data service for permafrost research and applications. This service was extended by permafrost modelling (time series), implemented in the new ESA CCI+ Permafrost project (2018-2021). The service comprises of the generation of remote sensing products for various regions and spatial scales as well as the specific infrastructures for visualisation, dissemination and access to datasets - PerSys. PerSys is the ESA GlobPermafrost geospatial information service for publishing and visualisation of information and data products to the public. Data products are described and searchable in the PerSys data catalogue (, and data visualisation employs the AWI WebGIS-infrastructure maps@awi (, a highly scalable data visualisation unit within the AWI data-workflow framework O2A, from Observation to Archive. maps@awi WebGIS technology supports the project-specific visualisation of raster and vector data products of any spatial resolution and remote sensing origin. This is a prerequisite for the visualisation of the wide range of GlobPermafrost remote sensing products like: Landsat multispectral index trends (Tasseled Cap Brightness, Greeness, Wetness; Normalized Vegetation Index NDVI), Arctic land cover (e.g. shrub height, vegetation composition), lake ice grounding, InSAR-based land surface deformation, rock glacier velocities and a spatially distributed permafrost model output with permafrost probability and ground temperature per pixel. We established several WebGIS projects for the adaption to products specific spatial scales. For example, the WebGIS ‘Arctic’ visualises the Circum-Artic products. Highly resolved data products for rock glacier movements are visualised on regional scales in the WebGIS projects ‘Alps’, ‘Andes’ or ‘Central Asia’. The PerSYS WebGIS also visualises the stations of the WMO GCOS ground monitoring networks of the permafrost community: the Global Terrestrial Network for Permafrost GTN-P managed by the International Permafrost Association IPA. The PerSYS WebGIS has been continuously adapted in close co-operation with user at user workshops and at conferences and the International Permafrost Association (IPA).
