Description

more
This layer resumes the hydrographic network of the Democratic Republic of Congo represented in a linear form. It includes the River, the main rivers, the secondary rivers, the tertiary rivers, the semi-permanent rivers and the lake. It was first produced by the Inventory and Forest Management Directorate on the basis of large-scale interpretation (1 / 50,000) of Landsat satellite imagery, followed by technicians from the Provincial Environment Coordinators of Bandundu, Ecuador and P. Orientale as part of the Spatial Information Management System (SyGIS) project. The attribute table was filled with the basic maps of the Geographical Institute of the Congo, extracts from forest title maps deposited by logging operators and the field knowledge of MECNDD agents. The original cartographic data has been produced with the technical support of World Resources Institute (WRI). Original data has been created since 2008 as part of the project to convert old forest titles to forest concession contracts. Day is carried out according to the availability of the data.
