Ideas
Process of creating a 3D map of the area
Resources
- OceansMap, a well-aggregated set of realtime data about major bodies of water around the world, including the Great Lakes region
- Historical maps from the Army Corps of Engineers
- Portal for Great Lakes Observing System information from the Integrated Ocean Observing system
- Downloadable Great Lakes bathymetric maps from NOAA
- Google maps
- Further information from the Great Lakes Information Network
- The National Map combines many of the above resources
- The USGS Earth Explorer is easier to use than the above, but requires a login and download client
Workflow
- Download shapefiles from Natural Earth or other files from NOAA
- Download and install QGIS and Inkscape[1]
- Open with QGIS Desktop, realize the data is only for oceans...
- Download bathymetry information from each lake from NOAA here
- No need to extract files, open each in QGIS Desktop
Other Sources
- Earth satellite imagery from USGS, esp. those over time
