ArcGIS Online imagery basemap was updated to include more recent global imagery, initial states of 2015 NAIP imagery, new contributor content, and additional imagery at the newly expanded largest map scales. The Arctic Imagery basemap was also updated. View this map tour to see areas of the map that have recently been updated.
World Imagery Global Small Scales
Our most popular basemap, World Imagery, has areas refreshed with TerraColor Global Satellite Imagery at the global small scales (~1:591M to ~1:577K). Two of the many areas that changed in this 15m resolution imagery are highlighted here. The remains of what was once the Aral Sea along the Kazakhstan-Uzbekistan border show the effect of diverting the water for agricultural irrigation. The eastern basin is now called the Aralkum desert.

Another area of improvement in the imagery basemap is the reduction of cloud cover. This image shows northwestern Mindanao, Philippines, in a “before and after” snapshot. The imagery basemap now contains less cloud cover (right) over a number of areas including the islands in southeast Asia.
2015 NAIP Imagery
We also added 2015 National Agriculture Imagery Program (NAIP) imagery from the USDA Farm Services Agency for several states. This 1m update covers Delaware, Maryland, New Jersey, South Carolina, and Washington, DC. The new imagery is viewable at scales ~1:36K to ~1:4K. In future releases, we plan to add the other states flown in 2015 to our World Imagery basemap.

Community Maps for Imagery
Contributions to the Living Atlas of the World through the Esri Community Maps for Imagery program enhance content for 11 communities in this release. We welcome four brand new contributors and seven updated communities. Most areas updated add content cached to the recently expanded scale levels 20 & 21.
With the new contribution from Toronto, you can easily count the shark-shaped custom four foot square, 110-pound slabs on the roof of Ripley’s Aquarium of Canada.
Toronto, Ontario, (0.08m) at Level 19
And at Level 21.

Additionally, we updated the Arctic Imagery map with the same TerraColor updates as the Web Mercator global small scale map detailed at the beginning of this blog. This is a separate basemap layer mapped to a stereographic polar projection. It displays from the northern pole down to 50 degrees north latitude. We are also working on a polar Antarctic imagery basemap forecasted to be released in early 2016.
