Announced last summer at the Esri International User Conference in San Diego, the first version of ArcGIS Earth is now available to download. ArcGIS Earth is a lightweight, easy-to-use 64-bit Windows desktop app that enables anyone in your organization to easily view and explore 2D and 3D data including KML and ArcGIS services, whether behind a firewall or over the Internet.
The data sources that you can explore with ArcGIS Earth can be local file or online (KML / KMZ formats or shapefile) or ArcGIS web services (Map Service, Scene Service, Feature Service, Image Service).
ArcGIS supports the OGC KML standard (KML 2.2.0). As such, Earth takes particular care of Network Links type elements or the Screen Image Overlays or Ground Image Overlays..
To share your ArcGIS 3D views from Earth, you can use the image export tool, the sending via email tool or printing tool.
ArcGIS Earth allows exploration, navigation and querying your data in a 3D environment but also provides other capabilities like the graphics drawing.
ArcGIS Earth also has tools for Measure, create placemarks and simple geometry, and more.
ArcGIS Earth is free and requires no subscription to ArcGIS Online or other ArcGIS licenses. Earth is fully integrated with the ArcGIS platform. Indeed, if you have an account on the portal of your ArcGIS organization (ArcGIS Online or Portal for ArcGIS), you can access to your content and those of your team in a secure environment.
