    I think you've earned it :)

    @cholmes
    And I want to get that Sentinel image on s3
    Fabian Schindler
    @constantinius
    Yeah, that'd be great
    Chris Holmes
    @cholmes
    Basically with GEE now you can take advantage of all their operations, combining multiple images, and then output the results as COG.
    So we can likely do some cool demo of some operations on GEE and then output and read the COG with cog-explorer / qgis / lambda tiler, etc.
    Fabian Schindler
    @constantinius
    That is awesome! (Of course, we'd love to do the ops in the browser)
    Chris Holmes
    @cholmes
    :) Me too... But Earth Engine has a lot of operations to catch up with...
    Fabian Schindler
    @constantinius
    Yep, indeed.
    Sorry, do you have control over that too? landsat-pds.s3.amazonaws.com
    Chris Holmes
    @cholmes
    no, not that one.
    Oh, and from before. I did email Joe F, but he didn't respond.
    Feel free to poke him again.
    Is the landsat-pds also needing the range option? How was it working before?
    Fabian Schindler
    @constantinius
    I don't know, it stopped working today, or yesterday
    Chris Holmes
    @cholmes
    Huh, that's weird.
    And it's just the CORS stuff that stopped working?
    Fabian Schindler
    @constantinius
    Yeah, @Schpidi did also poke him
    Yes

    @cholmes
    super odd

    joe was on vacation last week; i'm not sure when he gets back

    Matt said he turned on cors on google cloud.

    @cholmes
    Looks like it's working, but I'm getting weird technicolor versions

    but I'm now getting the same with the aws ones:

    Ok, cors should be enabled in my google bucket now! Matt got his working, and told me how to do it in mine. Looks like the Range thing was needed, and then options seemed to work? Unless trying it out directly in cog-explorer isn't a full test... I don't think I have a cors plugin installed.

    Hi @cholmes
    Sorry, I'm already home (its 9:30 here).
    Its great to hear you managed to get it to run, good job!
    I inspected the SanFranciscoS2BGRN.tif case. Theres two things: 1) The default contrast correction is way off as the image seems to be in a good contrast already by itself. I'm working on this issue (as it currently affects all RGB images). 2) if this image originates from Sentinel 2, then bands are a bit odd. In the gdalinfo it displays the band description as B2, B3, B4, B5 (which is actually Blue, Green, Red and Near Infrared) so the colors are quite odd indeed.
    The second image has the same contrast issue. If you click on the wrench in the upper right and delete the 'sigmoidal' step, then the image should be quite normal. The default settings originate from a version where we thought only Landsat 8 images will be displayed.

    Forgot to reply here, but thanks! Things seem to be working really now. I'm definitely going to talk this up a lot at foss4g-na, and I think a lot of people are going to be blown away.
    Also I think will aim to do a medium post that features it some. Also need to announce my cog-map + tiles.rdnt.io service we're standing up (marblecutter lambda tiler for cogs).
    Stephan Meißl
    @Schpidi
    yes, joe added the cors headers for l8
    Chris Holmes
    @cholmes
    oh awesome! I'll tweet that out...
    and include it in a blog post soon.
    Google Earth Engine is able to create COG's now - composited a bunch of planet scenes, clipped to land.
    cog-explorer actually did better on transparency than qgis and marblecutter...
    Stephan Meißl
    @Schpidi
    nice
    Fabian Schindler
    @constantinius
    Regarding the transparency: we cheat :D
    Chris Holmes
    @cholmes
    lol
    Fabian Schindler
    @constantinius
    We use black as transparent, this is why we see the fuzzy edges on JPEG images
    Chris Holmes
    @cholmes
    ah, gotcha. Well, whatever works - I'm never one to oppose cheating in technology :)

    Thanks a lot for that! Its great to have your support!

    Hi @cholmes! How's the conference? I've heard there was a COG BoF session? Any news?
    Chris Holmes
    @cholmes
    Hey @constantinius ! It's good. Cog BoF was quite good. Drew took some notes - https://cryptpad.fr/code/#/1/edit/5JKq9WUUR9DH607TR9zx7Q/8v6DcTnYmOdvB-D7wXwH0lr1/
    I need to check them over and add to them and I'll put a blog post on it.
    Fabian Schindler
    @constantinius
    Ah, great, I'll have a look!
    Chris Holmes
    @cholmes
    But I think we'll likely put the 'spec' on github, maybe make a little cog / cogeo github org, to put the website and the spec.
    But there was quite a bit of interest, 20+ people showed up.
    Fabian Schindler
    @constantinius

    Wow, sounds like its getting traction!

    But I think we'll likely put the 'spec' on github, maybe make a little cog / cogeo github org, to put the website and the spec.

    Sounds reasonable!

    Chris Holmes
    @cholmes
    Yeah, lots of enthusiasm here. And RasterFoundry just implemented COG importing, which works great as well.
