question about EE_folder #3

Closed tongqiugeog closed 6 years ago

tongqiugeog commented 6 years ago

Hi Yann,

Just have a quick question about the "EE_folder" and "EE_size" in your code.

EE_FOLDER = { 'LANDSAT_TM_C1': '12266', 'LANDSAT_ETM_C1': '12267', 'LANDSAT_8_C1': '12864' } SIZES = { 'LANDSAT_TM_C1': 150 * 10242, 'LANDSAT_ETM_C1': 235 * 1024*2, 'LANDSAT_8_C1': 919 10242 } I wonder where did you find such information?

Thank you very much for your help.

Best, Tong

Hi,

Yes, it's quite hacky.

For the folder variable, I just compared the URLs depending on the satellite platform in the EarthExplorer's interface. I still don't know the meaning of this numbers.

For the size variable, it is an estimation of the size of a dataset depending on the mission. This is because the information is not available in the HTTP headers (that is why there isn't any progress bar when you download a scene with your browser).

To be honest, I am rewriting everything based on the Public Cloud Dataset from Google. Download speeds are a lot better and credentials aren't needed. It's already working so don't hesitate to tell me if you are interested.

Hi,

I am very interested in the Public Cloud Dataset downloading. I wonder is the Landsat analysis ready dataset (ARD) also on that platform?

Hi, Here is a first version: https://github.com/yannforget/pylandsat ARD is not available in the public google cloud dataset. Yann
