| The Coastal Map Data Layer for Geographic Information Systems (GIS) Project began with the purpose to create a digital georeferenced data layer in order to provide the coastal stewardship community and general public with non-proprietary nautical chart images for GIS derived products. The nautical chart contains information critical to navigational users, yet obstructs a clear view of the topographic and hydrographic data. The charts are therefore cleaned of all navigational aides and symbols, then prepared as TIFFs (Tagged) Image File Format) in local Mercator projection. Federal Geographic Data Committee (FGDC) compliant metadata is available online. |
