Mapping the vegetation of the Lake Tana basin, Ethiopia, using Google Earth images
The basin of Lake Tana is one of the most important watersheds
in the Nile Basin. It is of great significance to the economy and politics of
Ethiopia. In the past, the natural vegetation of the Lake Tana basin was
heavily damaged to facilitate the continued expansion of cropland. Vegetation
must be conserved and restored to protect the natural environment and
maintain the biodiversity of the Lake Tana basin. In this research, we mapped
the vegetation of the Lake Tana basin through visual interpretation using
high-spatial-resolution images provided by Google Earth and field survey data
to provide detailed information of the actual vegetation state for planning
conservation and restoration. A total of 33 171 polygons were generated to
represent the vegetation patches of the Lake Tana basin on the map, and the
validation using surveyed vegetation plots indicated that 90 % of the
patches were correctly identified. The DOI of the dataset used for map
production is https://doi.org/10.4121/uuid:48d45053-36f6-411b-96b1-7ae0e22d56d0. We
expect that this vegetation map could benefit vegetation conservation and
restoration in the Lake Tana basin.</p
