Sediment Thickness of the World's Oceans & Marginal Seas

The map has been sent to MotherLode. If approved...

For advanced graphic cards, the pack has also the 8k png layers.
You can copy/paste the "st_8k.png" over your favorite 8k Earth' texture and
then save it as "st.png".

--------------------------------------------------------------------------------------------------
How to merge the ST 8k normalmap together with your favorite 8k Earth's normalmap:

- Open in a graphic editor the 2 textures and copy/paste your Earth's 8k normalmap within the
8k sediment thickness normalmap ("st_normal_8k.png");
- Shift the 8k Earth's normalmap layer beneath the ST 8k normalmap
- Set the 8k ST normalmap layer with the propriety "lighten" or "overlay"
- Make an unique layer (background) and save the image as "st_normal.png"

-------------------------------------------------------------------------------------------------
The dataset on which the textures are built comes from here:
http://www.ngdc.noaa.gov/mgg/sedthick/sedthick.html

Colors have been assigned through the discrete steps of the legend's numeric subdivisions.
White areas are not available data (NaN).

Thanks! Note though, that the manual intervenings have been the "overlaying" work; pixel points amongst colors haven't been blended.
