Hello, I would like to inquire if the recent downloads of velocity image pairs have been temporarily closed. I have been trying to download some velocity image pairs of Antarctica using a script that I previously used to download data. However, I encountered the following error: "requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://its-live-data.s3.amazonaws.com/velocity_image_pair/landsatOLI/v02/S70E160/LC08_L1GT_052117_20181015_20200830_02_T2_X_LC08_L1GT_052117_20181031_20201016_02_T2_G0120V02_P064.nc" Thank you for your assistance.

@yangt235 The granule path refers to the old dataset which no longer exists. The latest dataset is available under https://its-live-data.s3.amazonaws.com/velocity_image_pair/landsatOLI-latest/ (for now) but won't have one-to-one correspondence to old granules. For example, for the granule path provided above there is a new corresponding granule:

 % aws s3 ls s3://its-live-data/velocity_image_pair/landsatOLI-latest/S70E160/LC08_L1GT_052117_20181015_20200830_02_T2_X_LC08_L1GT_052117_20181031_20201016_02_T2_G0120V02

We are working of some corrections to the dataset and will let you know once it is available through the Data Access on our website.

Thank you for your help amidst your busy schedule. Based on the information provided, am I currently unable to access the desired image pair data? Also, I would like to know when the new dataset will be available. I am excitedly looking forward to it. Thank you again for your assistance.

mliukis commented 1 year ago

@yangt235 Just to let you know that we are working on fixing the issue and making the latest available data accessible by the users. It might take another day or two. I will let you know once it's fixed.

mliukis commented 1 year ago

@yangt235 The data access as provided through the ITS_LIVE web site should be working now. Thank you for your patience.

yangt235 commented 1 year ago

@mliukis I would like to express my sincere gratitude for your assistance and commend your team for their exceptional work.But I just searched through this https://its-live.jpl.nasa.gov/ and found that the imagery from Landsat 8 satellite is still not available for download. Do I need to wait a little longer for it to be fixed?

mliukis commented 1 year ago

@yangt235 Could you, please, clarify what region and search criteria don't return expected L8 data

yangt235 commented 1 year ago

@mliukis Of course, the polygon coordinates : 164.852,-75.6722,165.206,-75.3117,160.353,-75.0116,160.729,-75.5883,164.852,-75.6722.(https://github.com/nasa-jpl/its_live_production/assets/88574896/e74bd800-443d-4682-8c72-03e0ab075118). I have noticed that this seems to be the case for the entire Antarctic region.

mliukis commented 1 year ago

@yangt235 Thank you for catching it. It's all fixed now :)

yangt235 commented 10 months ago

Excuse me, I'd like to know which data cube I should access if I want S1 granules with temporal baselines of 24d, 36d, and so on. I found that I cannot directly download these from ITS_LIVE web site.
