This polyline shapefile depicts single-line drainages and lake centerlines worldwide ranked by relative importance. Includes name and line width attributes for creating tapered drainages. River data is primarily derived from the World Data Bank 2. All rivers received manual smoothing and position adjustments to fit shaded relief generated from SRTM Plus elevation data, which is more recent and (presumably) more accurate. Turn on centerlines to avoid data gaps. These data are represented at 1:10,000,000 scale. This layer is part of the Natural Earth Collection (v.2.0.0). Natural Earth is a public domain map dataset available at 1:10, 1:50 and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. Kelso, N.V. and Patterson, T.
