Share a brief history of your project and organization

Share a brief history of your project and organization: sdcloud is a distributed storage system developed based on blockchain and distributed storage technology. It perfectly solves core issues such as "protecting data privacy" and "reducing storage costs", and provides a reliable data storage solution for privacy data security and ownership issues in the big data era.The personal end-to-end login method is more convenient, providing private storage space and public data sharing platform for personal accounts. Work files, life records, videos, audios, photos and other documents can be stored in the cloud anytime and anywhere, and the download speed is increased by more than 60%. With data slicing storage, private key support and content addressing technology, there is no need to worry about the hidden danger of private files being peeped.

Is this project associated with other projects/ecosystem stakeholders?

No

If answered yes, what are the other projects/ecosystem stakeholders

The Landsat-8 satellite carries two sensors, the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).
Landsat-8 is basically the same as Landsat 1-7 in terms of spatial resolution and spectral characteristics. The satellite has a total of 11 bands, with bands 1-7 and 9-11 having a spatial resolution of 30 meters, and band 8 being a panchromatic band with a resolution of 15 meters. The satellite can achieve global coverage once every 16 days. Landsat 9 is the newest satellite in the Landsat series. It is scheduled to be launched in December 2020 by an Atlas V 401 rocket from Vandenberg Air Force Base in California. It was actually launched on September 27, 2021, and has begun collecting the first batch of data. Remote sensing data was obtained on October 31, 2021. Landsat 9 is an irreplaceable record of the Landsat series' observation of the earth's surface. To reduce construction time and the risk of observation gaps, Landsat 9 largely replicates its predecessor, Landsat 8.

Application is waiting for allocator review

@Alin11155
Thank you for your submission. Upon review, I noticed that the dataset you intend to store originates from NASA. The description of this dataset should be significantly different. This will help other Filecoin users easily identify the dataset.

Please note that we are aware that this is your 3rd application to our pathway (1st, 2nd). Why do you keep changing the dataset you want to store as well as the accounts you apply from? This does not build trust in you.

@dampud
Because 1st time we miscalculated the size of the data sample, so it was closed.
2nd time, we try to open our dataset as open-dataset, but you said it was no value. It was closed.
3rd time, we try to use open-dataset with large size , you said it was from NASA again, But i didn't find it on NASA. Can you give me the data link on NASA?If all the data on the website all from NASA?
Why we apply again and again? It was because we have prepared enough tokens and find our partners. We have made a detailed plan. But it always gets rejected on the source link of the dataset。In order to distinguish the application for each account, so we change account all the time. If you have any distrust, you can KYC us. All the thing are the truth. And we are happy that you can tell how to be succeed in the application. we can correct it.
Hope you can give me the correct (The Landsat-8 satellite) sample link on NASA. And then i will make the application again.

Kindly note that the preparation of data and its accurate description should be the client's responsibility, not the allocator's.

For context, the Landsat satellite program is operated by USGS and NASA. GScloud does not own this data but acts as a platform that redistributes it. Similarly, when data is shared on the Filecoin network, neither GScloud nor the client becomes the owner of the data. Access to this open data is facilitated through various public portals.

While the data source is relevant, it is equally critical to specify the exact scope of what will be stored to justify the requested DataCap. Applicants should clearly understand and define what they intend to store at the time of application. For example, providing a .csv file with a detailed list of the data prepared for storage can be helpful in this regard.

Without such detailed information, it becomes challenging to justify the requested DataCap.

We kindly request you to:

Gather all necessary information and provide a detailed description of the files or dataset that would explain it's scope and size.
Ensure the ownership information for the dataset is accurate.
Clarify the details regarding your project (as it appears you may not be representing GScloud).
Once this information is provided and complies with the outlined policies, we will proceed further.

Furthermore, all applicants should already be familiar with the policies outlined in the Open Data Pathway Policies before initiating the application process. Adherence to these policies is mandatory and non-negotiable.

@dampud Thank you for yur warm explanation，Here are my further answer.
Yes we have some mistake with the data source. And then we found the data real resource: dataset: https://www.usgs.gov/landsat-missions/landsat-collection-2-level-2-science-products
Brief introduction about the dataset: Landsat Collection 2 science products are internationally-recognized as Committee on Earth Observation Satellites (CEOS) Analysis Ready Data (ARD). This certification recognizes satellite data that have been processed to a minimum set of requirements and organized into a structure that allows for immediate analysis with minimum user effort and interoperability both through time and with other datasets. Landsat data have become an invaluable resource for understanding and monitoring the Earth and its natural resources. The long temporal record, global coverage, free and open access, and versatile applications make Landsat data an ideal tool for learning and advancing remote sensing skills and studying global and regional trends and patterns. There are numerous educational resources for learners of all ages and experience levels.

We have checked the data size. It is more than 600TiB. And we will cooperate with 9SPs above. And we will add more SPs in the future. The tokens are enough, and sp are ready. Please let me know if you have any question. Thank you so much.

@Alin11155
Thank you for clarification.

1. Have the data already been prepared and indexed.
2. Will an index of the files be created during the preparation process to enable potential access for other community members ?
3. Do you know the exact scope of the data that will be stored at this point ? If so, can you justify the size (600TB)? Since access to the specified S3 bucket is not open, it is not easily verifiable.

Please correct the initial application form (you can provide document based on which i will edit the "github issue" to ensure it contains proper information. Keep in mind that all fields should be filled out, without leaving bland fields without response if that is applicable.

@dampud Sorry i don't know cannot process multiple parallel applications. If have to close one , i prefer close #123 and reopen #93. We can discuss the our sdcloud data. Thank you so much. It is my fault. Let talk about #93 Ok? Sincerely.
