وصف قصير

⧼wm-license-information-description⧽
English: Lake Superior bathymetric shaded relief map contoured with interval 25 m (100 m with thicker lines). The deepest point, roughly off its southeastern shore, is marked with "×". For land, the vertical datum is sea level; for bathymetry, low water datum of the lake.

According to NGDC information, Lake Superior data this map is based on are incomplete.

The map was created using the Generic Mapping Tools, GMT, version 5.1.1.

The coordinates of deepest point are taken from the NOAA Great Lakes Environmental Research Laboratory webpage (www.glerl.noaa.gov/, kml file Google Earth Great Lakes Tour).
The contours are generated by the GMT program, not downloaded from the NGDC website because they are not available for Lake Superior.
The color palette of the depth scale was made to be more or less similar to the color palettes used on the NGDC maps of other Great Lakes.
