S411 ice charts for ECDIS
This site gives access to several ice charts in the S411 format intented for ECDIS and some information about the S411 format. The collection of legacy ice charts were mowed to https://www.icelogistics.info/ in 2025. The restructuring of this website to a S411 centered page is just taking place and should be finished in late summer, early autumn of 2025.
The sea ice charts in S411 format are intended for the use in an ECDIS (or another GIS). Please contact your ECDIS Provider if your system is still not capable for this.
Available actual ice charts are:

The previews are done with a simple python script and just should give an idea of the S411 content. The used colors are not transparent (as they would be as overlay for ECDIS), but solid. Depending on the region, the charts are shown in polar stereographic or mercator projection.
Actual charts as well as previous version are also available over ftp at ftp://ftp.bsh.de/outgoing/Eisbericht/S411/. Some background information is given here.
