Hi folks,

We're thinking about building a marine navigational system in Squeak 
for the Microship project <http://www.microship.com>. Squeak will 
already be doing a lot of other things (including talking to a GPS) 
so it makes sense to have it do charts as well.

There are a number of free charts available in a vector form called 
IHO S-57. We'd like to use them if possible.

However, before starting to do something like this ourselves (Steve's 
not too sure that this would be a good first Squeak project), it 
makes sense to ask whether anyone else has done this in Squeak or 
another Smalltalk. There is some open source code in another language 
that we can look at if necessary.

So: has anyone out there done any mapping/GIS/charting applications 
using Squeak? Might you be willing to share your code?

Thanks,
