Using Nautical Charts
and Bathymetric data with GIS
We
use scanned nautical charts for:
* environmental assessments
* cultural site assessments
* illustrating harvest areas
* mapping fisheries infractions
* canoe journeys (another presentation)
* shoreline access for clam digging
* monitoring commercial clam harvests
* half or quarter scale charts for field
use
* illustrating sewer outfalls
…
and many other projects.
Not
just for saltwater - NOAA has
nautical
charts for all navigable waters,
including
major lakes and rivers.
