Imagery and Street Maps Enhanced

Updates, Expanded Map Coverage Highlight ArcGIS Data Appliance

The latest release of ArcGIS Data Appliance includes significantly enhanced map offerings. The imagery and street map data on the preconfigured network storage device have been updated, and coverage has been expanded to ensure that users have access to the most efficient and consistent data they need for their critical projects. ArcGIS Data Appliance, which powers ArcGIS Online, is used by many organizations that need reliable access to high-performance data and tasks behind their firewalls.

Esri's imagery offerings have now been combined into one unique service on ArcGIS Data Appliance. All the previously available offerings, including World IKONOS Cities Imagery, World Imagery, and USA Prime Imagery, have been merged and blended, along with new high-resolution imagery for the United Kingdom, such as Getmapping, and other countries. The best data from each service was used to provide the optimal vintage, resolution, and coverage for the new imagery collection.

The World Street Map offering has been updated with improved cartography. The new better-looking maps now also include building footprints. The maps for North America and Europe have also been updated to 2009 data from Tele Atlas/TomTom and AND Mapping. For Europe, the street map has expanded coverage for the largest-scale level (1:5,000 meters). International coverage has also been expanded to include detailed street maps for Colombia, Hong Kong, Japan, and Thailand.

All the maps available on ArcGIS Data Appliance have been migrated to a new tiling scheme in the latest release. They are now in the Web Mercator Projection, 256 x 256 pixel tiles with refined scales. This is the same tiling scheme used by Bing Maps and Google Maps, allowing users to more easily create mashups with other popular Web maps. All Esri maps will soon be in the same projection, simplifying caching decisions for ArcGIS users.

As ArcGIS Data Appliance powers ArcGIS Online, all these updates and enhancements will also soon be available on the online map services.
