Abstract

Permafrost regions are highly sensitive to climate changes. To monitor key variables and to identify environmentally relevant-processes is of topmost importance in these environments. Beside data analysis and map creation capabilities, Geographical Information Systems (GIS) also comprise functionalities for mobile data acquisition in the field, data transfer, data monitoring, data description, as well as data sharing and publication of data as WebGIS Services (Web Map/Feature Services (WMS, WFS)). Due to their excellent usability GIS technology and services are very common in many scientific disciplines all over the world, and since most data formats are standardized data re-use and data interchangeability are guaranteed. We visualize field-derived and remote sensing derived research data, collected within Russian and German cooperation projects in the Lena River Delta, Laptev Sea Region (Siberia) on a Web GIS Platform. We visualize the locations of long-term discharge measurements and of soil sampling for organic Carbon and Nutrients. Geormorphological feature classes derived from satellite data and publicly available environmental data layers (e.g. vegetation, soils, and digital elevation models) display the broader regional and thematic context. AWI offers WebGIS services published under http://maps.awi.de/awimaps/. The WebGIS core components are ArcGIS for Server 10.3 and PostgreSQL databases 9.3 including Spatial Database Engine (SDE).
