Describe the data being stored onto Filecoin

"GeoMAD is the Digital Earth Africa (DE Africa) surface reflectance geomedian and triple Median Absolute Deviation data service. It is a cloud-free composite of satellite data compiled over specific timeframes. The geomedian component combines measurements collected over the specified timeframe to produce one representative, multispectral measurement for every pixel unit of the African continent. The end result is a comprehensive dataset that can be used to generate true-colour images for visual inspection of anthropogenic or natural landmarks. The full spectral dataset can be used to develop more complex algorithms. For each pixel, invalid data is discarded, and remaining observations are mathematically summarised using the geomedian statistic. Flyover coverage provided by collecting data over a period of time also helps scope intermittently cloudy areas. Variations between the geomedian and the individual measurements are captured by the three Median Absolute Deviation (MAD) layers. These are higher-order statistical measurements calculating variation relative to the geomedian. The MAD layers can be used on their own or together with geomedian to gain insights about the land surface, and understand change over time. Calculating GeoMAD over different timeframes and sensors provides a range of insights to the environment. An annual timeframe allows better correction for cloud cover and reduces artifacts for comparison over multiple years. A semiannual timeframe, for example six-month blocks, better captures seasonal variation within one year, but can also be used to compare equivalent periods from different years. Likewise, Landsat sensors allows full utility of the surface reflectance archive dating back to 1984, while more recent Sentinel-2 data provides higher-frequency flyovers and better resolution. The Digital Earth Africa GeoMAD service currently provides annual and six-month semiannual datasets, with separate services for Landsat and Sentinel-2 sensors."

Do you want to store these data in this application? How many copies you will store?

@Sunnyiscoming Considering the retrieval success rate, we will store the 14 copies to the Filecoin network. The buckets data size about 190TiB, every piece size will be 16GiB(required 32GiB datacap), so all data need 1901024/1632*14/1024=5320TiB datacap.

@hengdingy Hello ,Looking at your application i have some questions: 1.Are these data completely public？ 2.Is it randomly assigned to the storage provider you listed or specified？

@hengdingy Hello ,Looking at your application i have some questions: 1.Are these data completely public？ 2.Is it randomly assigned to the storage provider you listed or specified？

@zcfil yes, all datasets are from https://registry.opendata.aws/deafrica-geomad/, they are completely public.

and all datasets will be assigned to the storage providers by FilSwan's bidding engine. The lists of storage providers in the application are just some of the active storage providers. The dataset will be assigned to more than the listed storage providers.

@galen-mcandrew @raghavrmadya @Kevin-FF-USA Because my hardware wallet has not been updated to the multi-signature address f02049625 for a long time, my use of the lotus command to sign did not trigger the above git message reply. Can I do this? Because I have been reviewing LDNs for a long time and have not contributed to the community, I am in a hurry.
