Data of the Baikal Web GIS

As supplementary material to their paper "Assembly and concept of a web-based GIS within the paleolimnological project CONTINENT (Lake Baikal, Siberia)" by B. Heim, J. Klump, H. Oberhänsli and N. Fagel, the authors published all data of the Baikal Web GIS though SDDB. [more ... ]

Abstract

Web-based Geographical Information Systems (GIS) are excellent tools within interdisciplinary and multi-national geoscience projects to exchange and visualize project data. The web-based GIS presented in this paper was designed for the paleolimnological project CONTINENT (Lake Baikal, Siberia) to allow the interactive handling of spatial data. The GIS data base combines project data (core positions, sample positions, thematic maps) with auxiliary spatial data sets that were downloaded from freely available data sources on the world wide web. The reliability of the external data was evaluated and suitable new spatial datasets were processed according to the scientific questions of the project. GIS analysis of the data was used to help answer questions such as how to quantify the sediment source provinces to assist studies on sediment provenance in Lake Baikal, and whether the visualisation of present-day vegetation distribution and surface pollen distribution supports the conclusions derived from palynologic analyses. The refined geodata are returned back to the scientific community by using online data publication portals. Data were made citeable by assigning persistent identifiers (DOI) and were published through the German National Library for Science and Technology (TIB Hannover).
