Updates to DigitalGlobe imagery layers

Posted by @kevin_bullock on 28 June 2019 in English (English)

DigitalGlobe, now Maxar [1], is transitioning the OpenStreetMap imagery endpoints (from “DigitalGlobe Standard” to “Maxar Standard”; and from “DigitalGlobe Premium” to “Maxar Premium”). OSM users should see content parity between the old and the new layers by June 30, 2019. Starting July 1, 2019, there will be only two Maxar layers available from within the OSM editors – labeled with Beta.

Our new imagery services use http/2 protocol. Please note that there are some known speed issues with the JOSM editor. A JOSM plugin for http/2 support is expected before the end of July (ticket #17861). In the meantime, increasing the concurrent connections (e.g. to 20) will help. iD editor already supports http/2.

The good news: imagery will be more recent and more frequently updated with our latest Maxar mosaic content. We hope that our improved production processes (bundle block adjustment, atmospheric compensation, continuous updates, etc.) will benefit OSM contributors.

As always, thanks to everyone within OSM for all your support and feedback. Shout out to the maintainers and contributors for iD and JOSM who have been fantastic to work with. Look for Maxar at State of the Map and State of the Map US; we will be attending and presenting more information on this new image service. And please feel free to send us feedback. Happy editing!

Thank you for all your contributions! DigitalGlobe access has been an incredible asset to the OSM community.

Appreciate the feedback Omnific!

Thank you Maxar/DigitalGlobe for sharing the imageries! Are there any channel to submit feedbacks e.g. a small patch of cloudy area in my area of editing interest?

Thank you, I’ve been using your imagery for a while now, good stuff. Some places have been updated for the first time since 15 years. It immediately rendered my GPX traces obsolete.

Could you shine some light on image quality (resolution/clarity) and alignment? I would like to understand what the limiting factors are (e.g. technology, licensing) and if there is a short or long-term improvement expected. For example, imagery at google.com or even bing.com(!) is clearer, sometimes a lot clearer, than what I see in jOSM.

Thanks for the update, Kevin! In some cities currently DG Premium has more recent imagery than any of the Maxar layers. I hope the latter will be updated soon :)

AkuAnaktimor - sure, please send a coordinate!

ndrw6 - the resolution of our satellites range from 30cm-50cm per pixel. This is amongst the best resolution available via satellite. The reason why there are higher resolution images on Google or Bing is because they are also using aerial surveys in places like the US and Europe. Due to the lower flying aircraft, they can resolve a better resolution.

Zverik - we should have parity or better soon, or hopefully now. Feel free to send a specific location if you see this issue persist.

Thanks all for the feedback!

Thanks for the very welcome updates Kevin! One day I’ll hopefully start actually purchasing small areas of your imagery, but will enjoy it in osm for now

NDR-w6, additional higher resolution images can be seen in the us from mapbox in some locations, which have trickled up to one of the dg layers in the past in pixellated form. also, esri as a collective of at least hundreds of sources ranges from dg-matching imagery to much higher resolution (i think i saw native z23 details in a small part of us state hawaii). the esri clarity layer is about a decade old but matches what bing used to offer from aerial overflights.

then of course there are localised regional offerings that can be much better with pixel resolution to a handful of cm.

as i do not know your area of mapping interest, i give generic guidelines here based on my experience. as always, it is a compromise whether the ``best’’ (i think these quotes will get swallowed) imagery layer should be the newest, or the clearest.

thanks kevin, i almost always cycle through all tms imageries available for my worldwide mis-mapping and the wide choice you offer is much appreciated.

Like what AkuAnaktimor said, some of the imagery are cloudy. Hope MAXAR can update for it and adjust the imagery into right position as now most of the imagery coverage in Malaysia has a big offset compared to older DG Premium imagery. Cloudy area in Malaysia need to replace with a crispy imagery Bahau, Negeri Sembilan 2.81017,102.39802 Seremban, NS 2.72855, 101.95497

where I can change concurrent connections?

Comment from HeyItsAdam on 7 July 2019 at 20:33

Both of my region’s premium / standard imagery are the same. My assumption is that the premium imagery is only in select locations?

Thank you for your great work. I’m from Iran and now in compare with previous DG imagery many more areas have a more recent and clear imagery!

BTW there is a misalignment about 8m that shows itself on top of the bridge at 34.09814158102221, 49.72359001100064.
