The Arctic Permafrost Geospatial Centre (APGC)

With support of the ERC Starting Grant project PETA-CARB we are establishing the Arctic Permafrost Geospatial Centre (APGC) at AWI. The APGC is designed as a web interface showcasing high level projects with permafrost focus and provides an entry point for their geospatial product dissemination needs. With support from the AWI Computing and Data Center the APGC has been linked with other AWI data infrastructure components (e.g., PANGAEA) to facilitate and sustain coherent discovery, view, dissemination, and archival of permafrost geospatial information. In addition to featuring ERC PETA-CARB project datasets, the APGC has already been selected to also feature datasets from other relevant projects, namely the IPA Action Group on Ice Rich Yedoma Distribution and Characteristics and the European Space Agency (ESA) project GlobPermafrost.

First components of the APGC portal are scheduled to go online in 10/2016 with a first selection of datasets from these projects. The APGC can also be used by other AWI groups and international partners to store and serve permafrost-related geospatial information to the public through a webserver. We hope to grow the APGC to become the place to go for discovery of spatial datasets relevant for permafrost research on all scales.

The APGC features two core services for data discovery: an Open Access Data Catalogue and an Open Access WebGIS Application.

The Data Catalogue allows searching for project-specific geospatial data by tags, keywords, data type and format, licence type, or geographically, provides a data preview figure, localizes the dataset on a zoom- and pan-capable basemap, displays a variety of metadata, and links to a permanent DOI-based archival link at the PANGAEA data repository. The Data Catalogue is based on the open source CKAN data catalogue architecture, allowing geospatial data categorization associated with defined projects based on metadata standards.

The WebGIS application, currently still under development, will rely on OGC-standardized Web Mapping Services (WMS) and Web Feature Service (WFS) technologies for data display and visualization. The WMS/WFS services are provided through the Data Catalogue. The WebGIS Application will provide a platform-independent and visually interactive platform for displaying both raster and vector geospatial data from featured projects.
