Share a brief history of your project and organization

The EASIER Data initiative kicked off during the Summer 2022 and is a two-year project in collaboration with the Filecoin Foundation for the Decentralized Web to build pipelines for storing and extracting geospatial data on Filecoin and IPFS. We have onboarded a near 200+ TB (per replication) of Landsat 9 satellite data for a single year. Our pipeline development will utilize this content to prototype and demonstrate the capabilities of decentralized access of existing tools our team has built and tutorials that have been developed by the GEDI Science team.

Is this project associated with other projects/ecosystem stakeholders?

Yes

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

Describe the data being stored onto Filecoin

Deployed to the ISS, the Global Ecosystem Dynamics Investigation (GEDI) mission is a full-waveform lidar instrument that makes detailed measurements of the 3D structure of the Earth’s surface. Lidar is an active remote sensing technology (the laser version of radar) which uses pulses of laser light to measure 3D structure. The light is reflected by the ground, vegetation and any clouds and is then collected by GEDI’s telescope. The sole GEDI observable is the waveform from which all other data products are derived. Signal processing is used to identify the ground within the waveform. The distribution of laser energy above the ground can be used to determine the height and density of objects within the footprint. The view geometry and active use of light by lidar allows the ground to be identified through small gaps in the tree canopy, enabling unsaturated measurements of much denser forests than is possible with either passive optical (such as spaceborne cameras) or short wavelength radar systems. In addition, uniquely amongst satellite remote sensing, the height and vertical distribution are direct measurements than can be compared to field observations.

GEDI science data products include footprint and gridded data sets that describe the 3D features of the Earth in HDF5 and Geotiff format.

Additional details on the science objectives of GEDI can be found [here](https://gedi.umd.edu/science/objectives-overview/)

Where was the data currently stored in this dataset sourced from

AWS Cloud

If you answered "Other" in the previous question, enter the details here

NASA's Earth Observing System Data and Information System (EOSDIS) are stored and maintained across 12 Distributed Active Achieve Centers (DAACs).  Each of the DAACs have unique expertise serving science discipline-oriented user communities, therefore data retrieval can be served directly from an AWS S3 bucket (us-west-2 region) or HTTP endpoint maintained by the DAACs infrastructure.

If you are a data preparer. What is your location (Country/Region)

United States

If you are a data preparer, how will the data be prepared? Please include tooling used and technical details?

We'll be preparing data using Singularity-V2 by using the inline preparation capability and content distribution will be accessible to storage providers through our hosted EC2 instance.

If you are not preparing the data, who will prepare the data? (Provide name and business)

No response

Has this dataset been stored on the Filecoin network before? If so, please explain and make the case why you would like to store this dataset again to the network. Provide details on preparation and/or SP distribution.

No response

Please share a sample of the data

The following is from Earthdata Search, containing a list of publicly available collections from the GEDI mission.
