    Ok, I have a potential way for us to get help on this :)
    My friend Matt leads google earth engine dev, and they recently started outputting COG's...
    And he just gave me an example to test: https://storage.googleapis.com/mdh-test/SanFranciscoS2BGRN.tif

    @Schpidi
    yes, GET seems to work. so the CORS plugin is only needed for the OPTIONS request. from there on it works. sorry for the noise
    Chris Holmes
    @cholmes
    So hopefully he can get it working...
    Fabian Schindler
    @constantinius
    Ah, I'll try right away
    btw: about this image http://oin-hotosm.s3.amazonaws.com/56f9b5a963ebf4bc00074e70/0/56f9c2d42b67227a79b4faec.tif
    Now that we know how, do we know someone that can set the headers there too?
    Chris Holmes
    @cholmes
    though I'll try to bash around a bit more.
    @mojodna - do you have powers to set CORS headers on the OIN bucket?
    Fabian Schindler
    @constantinius
    https://storage.googleapis.com/mdh-test/SanFranciscoS2BGRN.tif has the same issue.
    Seth Fitzsimmons
    @mojodna
    i do
    looking now
    Chris Holmes
    @cholmes
    oh yeah, I was pretty sure it would. But if I rope Matt in about this he has access to all the google people. Instead of me just searching around online.
    Fabian Schindler
    @constantinius
    I see, now I understand
    Seth Fitzsimmons
    @mojodna
    current CORS configuration:
    <!-- Sample policy -->
<CORSConfiguration>
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration>
    err, maybe that was a sample
    Chris Holmes
    @cholmes
    I did: <CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>HEAD</AllowedMethod>
    <AllowedHeader>Range</AllowedHeader>
    (I think the sample just becomes the default when you enable it)
    Seth Fitzsimmons
    @mojodna
    ah, Range. makes sense
    Chris Holmes
    @cholmes
    Not sure if HEAD is actually needed
    Range seemed to be the magic incantation
    Seth Fitzsimmons
    @mojodna
    updated
    Fabian Schindler
    @constantinius
    Okay, it works if you use https:
    https://geotiffjs.github.io/cog-explorer/#long=168.457&lat=-17.554&zoom=16&scene=https://oin-hotosm.s3.amazonaws.com/56f9b5a963ebf4bc00074e70/0/56f9c2d42b67227a79b4faec.tif
    We have some strange artifacts in JPEG images on the border ...
    Thanks @mojodna
    Seth Fitzsimmons
    @mojodna
    that's "normal" (i want to get to the bottom of those, but they're in the overviews)
    whoa, awesome!
    Chris Holmes
    @cholmes
    sweet!
    Why do you need to use https: ?
    Fabian Schindler
    @constantinius
    Also a security issue. Browsers do not let you send unsecure requests from a secure origin, I think I can recall

    that's "normal" (i want to get to the bottom of those, but they're in the overviews)

    Ah, so no issue with the decoding, good to know

    Seth Fitzsimmons
    @mojodna
    no need to use HTTPS for S3, but i think those are the URLs that published in the catalog...
    Stephan Meißl
    @Schpidi
    usually you get a mixed origin warning
    Chris Holmes
    @cholmes
    Ok, psyched we got at least one working.
    I've got to shower and eat breakfast and get in to the office
    Fabian Schindler
    @constantinius
    Okay, do that
    Chris Holmes
    @cholmes
    But I'll see if I can try out some more google cloud configurations.
    Fabian Schindler
    @constantinius
    I think you've earned it :)
    Chris Holmes
    @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.
