Improvement parameters T1, 2 and RT ? #38

Open jacquesmoati opened 3 years ago

Hi, Thank you a lot for your api and repos. I would like to know if you are planning to improve the landsatxplore library with parameters selecting the category of images from the Collection 1 of LandSat 8 such that we can select Tier 1, Tier 2 or Real-Time images. Also, will it be possible to return only images that are concerned by SR treatment ? @jacquesmoati

Yes, a Tier search parameter would be relevant. In the meantime you can do it manually based on the Landsat Product ID. In LE07_L1TP_188054_20161229_20170219_01_T1, T1 refers to the tier. I think it's RT for real time images. Also the tier info is present in the scene metadata returned by landsatxplore.

What do you mean by SR treatment ? Collection 1 Level-1 images that are available for order (collection 1 level-2) ? For collection 2, all collection 2 level 2 images are processed to surface reflectance.

Thank you for your answer. Yes, concerning T1 T2 and RT it's exactly what I am doing right now, filtering on the 2 last characters.

In SR, I mean Surface Reflectance. For instance, not all images in the Collection 1 are concerned by further SR treatment such that Real Time images (RT). If you order to usgs such an image, usgs will send you an error.
