An announcement from ESRI and Microsoft.
Users of ESRI’s ArcGIS will now be able to directly load base map data from the Microsoft Virtual Earth platform into the ArcGIS 9.3 Desktop and Explorer. Data layers will include the high resolution street maps, imagery, and hybrid that we have become accustom to seeing in Microsoft’s Virtual Earth.
Access to this data requires a subscription to ArcGIS Online Service.
Imagery can be previewed at http://resources.esri.com/arcgisonlineservices.
