The Ocean Basemap contains more information about the ocean than any existing terrestrial basemap service. It includes bathymetric portrayal, marine water body names, undersea feature names, and derived depth values in meters. While you can't query the information in the Ocean Basemap, it is a superior cached cartographic representation of the seabed.
You will find higher-resolution bathymetric and altitude data from coastal areas that are the most surveyed parts of the ocean. Data tends to be plentiful along the shore and becomes sparser as one moves away from the coastline toward deeper seas.
The Ocean Basemap currently provides coverage for the world with a resolution down to a scale of around 1:577, 000. Additional data coverage for United States waters improves the resolution to 1:72, 000. High-resolution coverage in limited areas of US waters is available at 1:9, 000. Through Esri's Community Maps Program, the Ocean Basemap can and will be extended with higher-resolution bathymetric data for more areas.
The Map's Information Sources
The Ocean Basemap blends publicly available, authoritative ocean data sources into one cartographically uniform basemap. Global coverage for the Ocean Basemap was created with data from the General Bathymetric Chart of the Oceans (GEBCO), the National Oceanic and Atmospheric Administration (NOAA), National Geographic, DeLorme, and NAVTEQ.
Agencies, commercial businesses, academic institutions, and nongovernmental organizations can contribute authoritative data to the Ocean Basemap through Esri's Community Maps Program. Esri ensures data contributions are of high quality, and the datasets have permissions in place for public use. Esri's cartographers integrate newly contributed data with the map and publish it to ArcGIS Online as a map service. Read the full list of contributors.
How to Use the Ocean Basemap
The Ocean Basemap, created with uniform cartography, has a muted color palette that makes it ideal for overlaying custom content or content from ArcGIS Online. Maritime professionals, such as ocean scientists, port managers, and ocean use planners, now have a consolidated, uniform cartographic source to bring their research into the map. You can access the basemap through ArcGIS for Desktop or any of the ArcGIS applications for smartphones and tablets (iOS, Android, and Windows Mobile). That means that you have access to the same basemap anywhere, at your desk or on the go.
I loves me some maps, Taz
... thanks for the post.
I've seen some of these before. Some are nice, others, meh, and some I'm going to need to research more because the sources seem a little sketchy.
I'm currently reading a book about maps called "On The Map." So far it's mostly been about early history of cartography. As far as readability, it's kind of like reading a newspaper (which makes sense as the author is a NY Times columnist), and it is informative, but a bit dry.
