    Haiyan Huang,  I did a quick review of udm2 assets for PSScene4Band items for 2018, and it looks like we have these available for a bit less than 50% of items while we have them for essentially all...

    Kriti,    I assume you mean the "udm2" asset for PlanetScope imagery - is that correct?  There should be "udm" assets available for essentially everything that is published.  We recently built "udm...

    Marlon,   While this does not seem to be a Planet data related question, you can normally do something as simple as:   gdal_translate my_big_file.ecw my_big_file.tif   Many distributions of GDAL do...

    Janez Pers,  105c is one of our "next generation" PlanetScope satellites and uses a different sensor architecture.  There is some non-technical information on these new satellites at https://www.pl...

    Andrea, When you mentioned quota, did you mean some sort of network bandwidth quota close to your client or Planet's quota for purchased imagery?   If you mean Planet quota, did you confirm you are...

    Ryan, We are not currently able to give a great metric for positional accuracy.  If ground_control is True we believe we are within our positional accuracy specification, while when it is False we ...
