TopoFusion News

After announcing that (formerly Terraserver) will be closing permanently, Microsoft has decided to keep the service alive. They received enough requests from longtime users and folks that rely heavily on the service. If you sent a note in, thank you!

This has, in turn prompted us to release another revision that re-enables access to new MSRMaps tiles. So the traditional Topo maps, B/W aerials (still useful!) and urban imagery for some cities, are all back! The new USTopo layer is still available as well, so now there are three sources of Topo maps in Terraserver! The array of maps available to TF users continues to grow…

v4.6 also fixed a bug created by the massive size of this year’s Tour Divide race. The Trackleaders spot replay interface had a problem replaying the current race. Tour Divide is an exciting race that continues for weeks, so there is still time to get in on the action and do your own replays in TF. Check out more at:

    Hey Scott! Any idea what’s going on with the color aerials lately? No luck loading any of them (New Mexico) using either an older version of TF nor the latest. Looks like the various servers have been on the blink again lately; thanks for your efforts already. PS – You in Colorado this summer? I just completed a northern New Mexico loop trek; Sangres were fantastic and I’m eager for more! Santa Fe looks to be a great mtb town too.

    Oops – no need to post any of this publicly, ‘course.

  3. Scott Says:

    Hey Brett,

    The color aerial server changed — had to push out a new version (4.65) to fix the issue, also one with the US Topo and Open Aerial. Update and let me know it it doesn’t take care of it for you.

    Loving Colorado (now Utah) this summer, and, I really hope to spent some appreciable time in Santa Fe at some point…
