On the detailed zoom levels this WMS has everything that is also shown on the well-known OpenStreetMap style. For the smaller zoom levels (i. e. the larger map scales), the presentation has been optimized for faster display in a WMS environment and has less detail.
In contrast to reprojecting or scaling raster tiles, the WMS computes the perfect image for every map request. This results in the best possible image quality, without distorted fonts or other artifacts.

The EarthOnDrive-WMS supports high resolution output and can therefore also be used to produce raster maps for printing.
