FORCE

FORCE (Framework for Operational Radiometric Correction for Environmental monitoring) is an all-in-one solution for mass-processing medium-resolution satellite images

Available

FORCE is available in Puhti with the following versions:

  • 3.5.1 (Singularity container)

Usage

FORCE is included in the force module. You can load it with

module load force

By default the latest force module is loaded. If you want a specific version you can specify the version number

module load force/<VERSION_NUMBER>

Running FORCE commands

FORCE is installed as a container. This means you need to use singularity_wrapper to run its commands

singularity_wrapper exec <normal FORCE command>

If working interactively, you can also start a shell inside the container with

singularity_wrapper shell

and after that use normal FORCE commands

We have an example of running L1 to L2 pipeline for Sentinel images in our Github examples

Using FORCE to download sentinel images

For downloading files with FORCE you need ESA Scihub credentials. The credentials should be saved in your home directory to a .scihub file and. Username in the first row, password second.

Here is an example that finds suitable satellite images from an area and time with cloud coverage of 10% and downloads them. More information on Sentinel imagery download can be found from the FORCE documentation.

singularity_wrapper exec force-level1-sentinel2 /scratch/<PROJECT>/sentinel_images/ /scratch/<PROJECT>/sentinel_images/files.txt "60.15/24.77,60.25/24.77,60.25/25.04,60.15/25.04,60.15/24.77" 2020-03-01 2020-03-08 0 10
