This is however kind of my original point - the new satellite will likely not have much influence on what practically is available to the OSM mapper since what images can be and are taken and which are made available to the OSM mapper are two entirely different things. -- Christoph Hormann http://www.imagico.de/ ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

You are assuming that all of DG's imagery gets published in Mapbox/Google/Bing, which is incorrect.

That is a bold claim considering an estimated 1/4 of the world land surface is currently without any high resolution coverage in Bing, Google or Mapbox. > With our partnership with Mapbox, the OSM community will start seeing > this imagery through the Mapbox satellite layer; this will be of huge > value for mapping new areas and updating OSM. That would be great. I think i mentioned this before but it would be really nice if the Mapbox satellite layer provided information on the date of image acquisition. -- Christoph Hormann http://www.imagico.de/ ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] New mapping satellite
I am submitting an abstract to present WorldView-3 capabilities at SOTM in Nov. This is the third "WorldView class" satellite and its predecessors both achieve better than 3.5m CE90 (circular error, 90th percentile), and have since 2007 and 2009 when they were launched. WorldView-3 is expected to have similar accuracy. DigitalGlobe uses the entire constellation of 6 satellites to map the world. True there are many "task orders" we fulfill but the larger mission is to map the world. We can generally do this on an annual basis. With our partnership with Mapbox, the OSM community will start seeing this imagery through the Mapbox satellite layer; this will be of huge value for mapping new areas and updating OSM. Here are a couple videos from our launch yesterday: https://www.youtube.com/watch?v=UIPLDqDr59c&feature=youtu.be and my own personal video recorded from Lompoc, CA https://www.youtube.com/watch?v=1kULqDRP3r8 Kevin Bullock On Wed, Aug 13, 2014 at 5:01 AM, Christoph Hormann wrote: > On Wednesday 13 August 2014, John Sturdy wrote: > > Announced in typical Register style: > > http://www.theregister.co.uk/2014/08/13/creepy_satellites_will_be_abl > >e_to_zoom_in_on_your_face/ > > Mapbox has some more detailed explanations: > > https://www.mapbox.com/blog/worldview-3-launch/ > > including an positional accuracy number (3.5 meter) which is of course > just a claim at the moment and is likely for points exactly in nadir > position. > > Note the resolution number is a bit like the Megapixels in digital > cameras, it does not say much about the actual ability to resolve > details although in case of earth observation satellites pushing the > nominal resolution much beyond the optical resolution abilities makes > much less sense since it is very costly. > > In contrast to what the register article seems to imply these high > resolution satellites are not systematically mapping the whole planet, > they generally take images on demand for customers.

Note the resolution number is a bit like the Megapixels in digital cameras, it does not say much about the actual ability to resolve details although in case of earth observation satellites pushing the nominal resolution much beyond the optical resolution abilities makes much less sense since it is very costly. In contrast to what the register article seems to imply these high resolution satellites are not systematically mapping the whole planet, they generally take images on demand for customers. Practically it will probably mean that in the long term more up-to-date imagery will become available but mostly in areas where there generally are already less up-to-date high resolution aerial images. -- Christoph Hormann http://www.imagico.de/ ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
[OSM-talk] New mapping satellite
Announced in typical Register style: http://www.theregister.co.uk/2014/08/13/creepy_satellites_will_be_able_to_zoom_in_on_your_face/ I expect it'll be some time before images become available for OSM, though :-( And I'm not confusing resolution and accuracy! __John ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
