Seamless USGS TOPO! In ArcGIS

Someone emailed me asking if I had any luck using the National Geographic TOPO! extension with 9.2. My reply?

National Geographic TOPO! map series @ AGS Online


ArcGIS Online TOPO! in ArcMap

This layer presents land cover imagery for the world and detailed topographic maps for the United States. The layer includes NPS Natural Earth physical map at 1.24km per pixel for the world at small scales, i-cubed eTOPO 1:250,000 scale maps for the contiguous United States at medium scales, and National Geographic TOPO! 1:100,000 and 1:24,000 scale maps (1:250,000 and 1:63,000 in Alaska) for the United States at large scales. The TOPO! maps are seamless, scanned images of USGS paper topographic maps.

No sense in bothering with all those CDs and extensions anymore. What is even better is that you don’t need ArcMap to use this. Download ArcGIS Explorer or even ArcGIS Reader and utilize the layer.

    Am I the only one who gets a ‘HTTP503 – Service Unavailable’ when I try the ArcGIS explorer link?

    Something happened to that link because it doesn’t work anymore for me either… :|

    Seems like I can’t get to ArcGIS Online right now. Guess the 10 readers of my blog have overwhelmed the server…. ;)

    When I try to get it I get prompted for a user name and password. Any ideas?

    yeah, I used to dump all of this data into SDE to serve it seamless when such solutions didn’t exist. This is a lot better now. I can free up some storage space :)

    Do you know if this data will be available for free for non-commercial use? It would be great if I could use this layer in applications instead of Terraservice.

    @bryanc: From the FAQ…

    Q2: Is ArcGIS Online free?
