Alex,

I noticed the discussion on Slashgeo and thought of contributing, but I
didn't have too much to say.  There was a specific ASCII TIN format for
Arc/Info 7.x but I don't know that it is significant anymore.  Shapefiles
can be used for TINs, but OGR doesn't support the special types for that
very well (if at all), though shapelib can access them.  I don't believe
OGR supports any specific TIN formats.

Best regards,
