Curious - does anyone know where there is a database of depth soundings? (Lat, Long, MLWL) I feel like this should be cake for someone with a better programming background than me to extract from the NOAA S-57 files you can download. In fact, I think it'd be really cool if you could get all the "point" data out of an S-57 and put it into spreadsheet form for export into any mapping program. Any opionons on this?
