Hello, thank you very much for your interest in FORCE
The source code, and the corresponding user guide can be downloaded from here:
FORCE is intended for mass processing of medium-resolution satellite image archives. Thus, the hardware requirements are closely tied to the data volume of the envisaged project (space / time), as well as to the type of sensor (RAM / storage requirements for Sentinel-2 are higher than Landsats 4-8). Although the framework can also be used to process single (or a few) images, we generally recommend to use multi-CPU server systems. FORCE is command line software; a GUI is not provided
The software was developed and tested under Ubuntu 16.04, and 18.04 LTS operating systems. [However, we were able to successfully install and run FORCE on the Windows 10 subsystem for Linux, which can be enabled in developer mode. Nevertheless, a real Linux system is strongly recommended.]
Please refer to the user guide for installation and usage instructions.

Proper acknowledgement, and the citation of the scientific publications are kindly requested. Co-authorship of scientific articles should be offered in case I provide substantial help in setting up, modifying or running the software, or if the generated data are an integral part of your research. Please address questions to David Frantz. I will try my best to answer your query within a reasonable amount of time. However, please note that I cannot guarantee user support or an immediate answer, as this is not part of my full-time job. For inquiries about the installation, please refer to the user guide first; and if unsuccessful ask your administrator to set up the software before making contact. Inquiries about porting the code to non-supported operating systems, requesting a GUI, or similar requests will be ignored. Please read this user guide, as well as the scientific publications thoroughly before making any inquiries.
FORCE was developed by David Frantz at Trier University during the course of his Ph.D. thesis supervised by Prof. Dr. Joachim Hill, online available, as well as in the projects ‘Southern African Science Service Centre for Climate Change and Adaptive Land Management Project’ supported by the Federal Ministry of Education and Research under contract number FKZ-01LG1201C, and ‘Sentinel4GRIPS’ supported by the Federal Ministry of Transport and Digital Infrastructure and National Aeronautics and Space Research Centre of the Federal Republic of Germany under contract number FKZ-50EW1605, with intellectual contributions from Prof. Dr. Joachim Hill, Dr. Achim Röder, Dr. Marion Stellmes, as well as code fragments from Dr. Sebastian Mader. New FORCE functionality is currently developed by David Frantz at Humboldt-University Berlin in the project ‘Near-Real Time Derivation of Land Surface Phenology using Sentinel Data: the FORCE-NRT approach’, supported by the Geo.X Research Network for Geosciences in Berlin and Potsdam. Many thanks to the geomatics team at HUB for many new ideas and methods that have made it into FORCE.
