Color Schemes for Bathymetry Maps.

Summary

To show the nuances of water depth on bathymetric maps, the color scheme to mark the changes from one depth contour to the other is an important visualization task. This note shows graphically various schemes that may be suitable. Twenty-one schemes were evaluated. The schemes are first presented as small images, four to a page, after which a link is provided that allows one to download a detailed map of any of the 21 schemes looked at, and examine it’s impact. The one eventually chosen by the author is the very last scheme, scheme 21, or Figure 6b. What it shows pretty clearly, with easy-on-the-eye contrasting colors, is that the lake, as a whole, is shallower south of the Glendale bridge, especially the coves.
