How do I access Earth Observation (EO) data?

To access EO data you have to operate from a VM created from a project with EO data access (project_with_eo). If you want to create an additional project with EO data access - you may create it and then submit a ticket to our support so that we connect it to the EO data network - currently there is no automatic procedure to connect projects to the EO data.

Primary way of accessing Earth Observation data is using object interface to the CREODIAS EO Data repository.

Access S3 object interface using command line tools, development libraries or file system emulation.

In Linux:

Simple access to object is the repository is possible using s3cmd tool which is available in most of our standard VM images.

Linux images in CloudFerro cloud come with additional tool which emulates filesystem storage using S3 object interface: s3fs.

s3fs is used to mount the repository under /eodata mount point.

When you are at the VM with EO data access you should be able to see the full EO data directory tree under the catalogue: /eodata. Please try ls /eodata or df -h .

If /eodata is empty it means that the EO data storage was not mounted yet. You then have to execute sudo mount /eodata. Please remember that default images allow running sudo from eouser account.

In Windows:

Windows environment does not provide open source tool to emulate filesystem using object interface, therefore NFS proxy has to be used.

Double click the "mount_nfs" icon on the Desktop. The EO data repository will be mounted to disk Z:

Please not that the NFS interface has some limitations including very slow listing of directories which have thousands of objects in their tree (for example ls on daily production of Sentinel-2 may take substantial amount of time or even not complete due to protocol defined timeouts). Therefore it is recommended to go directly to product path which can be discovered using the product search tool: https://finder.creodias.eu
