FOSS4G
Overview
This presentation explores the power of open source in driving innovation, using the European Space Agency's (ESA) Earth observation missions, specifically the Biomass mission, as a case study. The speaker, Stephanie, shares her personal journey into open source, highlighting its empowering nature and the importance of community. The talk contrasts top-down institutional approaches with bottom-up community-driven innovation, emphasizing that true progress often stems from individuals and collaborative efforts. It delves into the lifecycle of space missions, from conception to operational phases, and discusses the challenges and opportunities of integrating open-source principles and practices within large organizations like ESA. The presentation advocates for a more unified and collaborative open-source ecosystem, particularly in the geospatial domain, to better represent collective interests and foster future advancements.

Chapters
- The speaker's initial interest in coding, sparked by geography and geovisualization, led to an introduction to open source through a NumPy core developer.
- Mentorship and participation in programs like Google Summer of Code allowed the speaker to develop and contribute to open-source geospatial packages.
- Open source empowered the speaker's scientific career by enabling publication of work and fostering a creative power to build necessary tools.
- The supportive and inclusive nature of open-source communities, like PySAL, was crucial for personal and professional growth.
Understanding the speaker's personal journey illustrates how open source can be a powerful catalyst for individual empowerment, skill development, and career advancement, especially in technical fields.
Being mentored by a NumPy core developer and later participating in Google Summer of Code to develop the 'esot' package for geospatial statistical visualization.
- The European Space Agency (ESA) is a collaborative organization of 22 member states focused on peaceful space research, technology, and applications.
- ESA's Earth observation vision aims to understand our planet through various missions, categorized into science (Earth Explorer), operational (Copernicus Sentinels), and meteorological missions.
- Earth Explorer missions, like Biomass, are novel R&D initiatives driven by specific scientific questions and are often proposed and developed bottom-up by a community.
- The Biomass mission specifically aims to quantify land carbon exchanges and carbon stored in tropical rainforests.
This chapter provides context on how large-scale scientific endeavors like Earth observation missions are structured and initiated within ESA, highlighting the importance of both scientific inquiry and community involvement.
The Biomass mission, an Earth Explorer mission, is designed to answer the scientific question of quantifying carbon stored in tropical rainforests.
- Space missions follow a lifecycle from Phase 0 (concept) to Phase F (decommissioning), with Biomass currently planned for a 2025 launch.
- Innovation in space missions, like in open source, is often bottom-up, driven by a community's concrete needs and a desire to build solutions.
- ESA experimented with open-sourcing the software ('processors') that translate raw radar data into actionable maps, starting with the 'Biomass Product Algorithm Laboratory' (bopal) project.
- This initiative moved from open-source algorithms to open-source software, adopting best practices like Git, documentation, reproducible environments, and continuous integration.
This section demonstrates how open-source principles can be applied to complex, long-term projects like space missions, fostering collaboration and accelerating development even before data is available.
The creation of 'bopal' (Biomass Product Algorithm Laboratory) as an open-source software project containing the official Biomass algorithms in Python.
- Inner Source applies open-source development best practices within an organization, bridging the gap between closed and open development models.
- Open source is more than just code; it involves crucial management tasks like governance, community building, licensing, and communication.
- Skills beyond coding, such as management and communication, are vital for the success and growth of open-source communities.
- The 'danger zone' (Phase D) of missions highlights potential conflicts between open and closed ideologies and opens debates about business models around open source.
This chapter expands the understanding of open source beyond just public code repositories, emphasizing its organizational and strategic implications, and the need for diverse skill sets.
The concept of 'Inner Source' allows organizations to adopt open-source workflows internally, making the transition to fully open-source projects smoother, as experienced with bopal.
- ESA faces challenges in funding open-source projects due to restrictions on moving funds outside member states, highlighting the need for better institutional structures.
- Decisions on which projects to fund should ideally involve community input rather than being solely top-down.
- The launch and commissioning phase (Phase E) is a moment of celebration, recognizing years of effort and the achievements of the open-source community.
- The operational phase requires demonstrating mission success by showing contributions to answering initial scientific questions, such as informing climate change policy.
This section addresses the practical and systemic challenges of supporting open source within large institutions and explores how successful missions contribute to ongoing scientific and societal goals.
ESA's Climate Change Initiative uses data from space to provide compelling evidence of climate change, informing policy and global stocktakes.
- Future innovation involves combining Earth observation data with other datasets (geospatial, vector, raster) to create more intelligent services.
- Initiatives like the 'Space for Green Future Accelerator' focus on building strategic partnerships with external 'green actors' to align efforts and resources.
- There's a move towards establishing independent, mission-driven non-profit bodies to reduce overhead and increase flexibility.
- The open-source geospatial ecosystem, though mature, is fragmented into 'tribes' (Python, Java, etc.); better representation and resource alignment are needed.
- The genius of open source lies in breaking down complex projects into manageable parts, a principle that could be applied more broadly across the ecosystem.
This chapter looks beyond individual projects to the broader ecosystem, advocating for greater collaboration, strategic partnerships, and a more unified approach to address complex global challenges.
The 'Space for Green Future Accelerator' initiative seeks to build strategic partnerships with organizations like DG CLIMA, Copa-Cogeca, and WWF to leverage space technology for the green transition.
- Successful missions don't just end; they transform, with data and learnings feeding into future projects or operational systems.
- Examples include Envisat transforming into Sentinel-1A, and CryoSat's legacy influencing the Copernicus Mission.
- The open-source community excels at breaking down projects and forming communities for individual projects, but could improve ecosystem-wide representation and collaboration.
- The speaker encourages learners to feel empowered by open source and the Biomass mission, recognizing themselves as 'makers' with the creative power to drive change.
This concluding section reinforces the idea of continuous evolution and legacy, both for space missions and for the open-source movement, emphasizing the lasting impact of collaborative efforts.
The transformation of legacy Earth Explorer missions like Envisat into operational missions like Sentinel-1A, demonstrating a continuous cycle of innovation and application.
