Ecological Atlas of the Baikal Basin: Cartographic Innovation

International experience in developing and generating the ecological atlas of the transboundary region, the Lake Baikal drainage basin, is provided. We examine the conceptual and organizational-methodological principles, the technique and practical results of mapping the natural and anthropogenic factors that are responsible for the ecological situation, the current state and transformation of the environment and its protection, and the present status of human health of a large region. We discuss the issues related to cartographic representation of the ecological conditions and factors along the shores and across the water area of Lake Baikal as well as to the incorporation of the thus produced atlas into the Internet.
