Microsoft Virtual Earth Update Will Challenge Google Earth

[NOTE: This article is from 2005, read the new story 6-November-2006 on Virtual Earth 3D]

Harris Corporation has announced their 15-meter global dataset has been selected by Microsoft for use with Virtual Earth. Harris Corp is well known in the visual simulation and training market for their databases, and the global dataset is reported to be very beautiful. It includes imagery which has been enhanced for accurate color representation.

If Microsoft is truly going to release 15-meter resolution imagery for the entire Earth, it will be a great improvement for vast portions of their Virtual Earth. Google Earth's global data is reportedly already at 15-m resolution, although it seems some areas are lower than this - the majority is certainly better. Many of the more interesting and more populated areas are down to even inches of resolution in the Google Earth data and they are adding to their coverage on a regular basis. Chances are Google will release more data possibly even before Microsoft releases theirs.

However, Microsoft really needs to create an application like Google Earth that enables their data to be mapped into 3D. Without that Google Earth will continue to be vastly superior for truly visualizing the Earth. Unfortunately, a lot of people still seem to not realize you can pan and tilt your view in Google Earth and see the wonderful 3D landscapes.

    I just love watching these two duke it out. I'm rooting for Google, but hey, I'll end up using which ever product is most useful to me...

    I'm curious, why does Microsoft need a 3D application? Until GE incorporates ortho-imagery, the 3D aspect is pretty limited for real world uses (beyond looking for you house you grew up in or what your high school looks like).

    James, if you're talking about "real world" uses being GIS use, your're right about GE. However, for visualizing 3D terrain scenery (especially mountainous areas), GE is certainly good for sightseeing and getting a feel for the lay of the land. Using the interactive pan and tilt features of a 3D application also lets you look around in ways you can't do with a 2D application. It enhances the user experience.

    hold it i read on google site that they cover the entire globe with 15 meter resolution

    yet u said there was 1 km

    Anonymous, you are right. I've modified the sentence you are referring to in order to clarify what I meant.

    I'd still wager that GE complicates the user experience for most people. Yes it allows some users to view data in a different way, but I'd bet you most average GE users don't even bother to tilt the globe.

    For not at least, 2 mapping in Google Maps/Virtual Earth is more important than the 3D Google Earth implementation.

    Exploring in 2D is boring... :(

    i agreee, 2d is garbage

    thats why gmaps stinks in comparison to gearth

    and virtual earth is the same thing, and even worse, virtual earth has horrible imagery

    did u see NY City????? its so horrible compared to google earth

    on top of that, i didnt see any of the 45 degree views they boast about

    did anyone see that screenshot that microsoft published of their softwrae (the one where u can see the building clear)?

    the actual quality is like a hundred times worse in the actual site

    We the GE users do tilt the globe, I am afraid, James Fee.

    Umm... We know MS product are cool. So cool that I, personally, and all my friends ever are so cold. I am sure that MSGlobe will not turn without unexpected errors.

    As far as I know MS was supposed to team up with www.pictometry.com. If they do, that will be very cool. I had a pictometry account for a little while and the images were great...

    I believe GE has world wide coverage of EarthSat NaturalVue Imagery. Which is pan-sharpened LandSat at 15m resolution

    Cool (blue -- though my favorite color is blue) is not good. GE's earth colors are so hot that you won't get a headache and your eyes do not shake. It is a big difference for our health which is a sign of Keyhole's respectiveness.

    The 15 meter dataset released by Harris is based on TerraColor imagery that can be view at www.resmap.com under the Free Imagery Link

    The medium resolution (15-meter) imagery on GE is MDA/Earthsat's NaturalVue product. The 15-meter imagery on Microsoft's Local.Live (ex Virtual Earth) is a version of my TerraColor product that was modified by Harris Corp. Both TerraColor and NaturalVue are "simulated natural color" products built using circa year 2000 pan-sharpened public domain Landsat satellite imagery processed by Earthsat for a NASA contract. Both have roughly equivalent resolution (detail). The main difference is in the "look" (color and brightness/contrast) of the imagery. The user can decide which they like better. See www.terracolor.net for details on the TerraColor product.
