FedGeoDay 2025 | Lightning Talk - Emma Paz

Emma Paz from Development Seed discusses the process of data aggregation, focusing specifically on the Commercial Satellite Data Acquisition Program (CSDAP), where she serves as the technical lead. CSDAP is responsible for acquiring commercial satellite data and making it accessible to researchers. Emma explains that managing the massive volume of geospatial data (over 30 petabytes) from diverse satellite sensors presents a significant challenge, likening it to finding a "needle in a haystack." She emphasizes that effective data discovery relies heavily on rich metadata. Development Seed addresses this by utilizing the STAC (SpatioTemporal Asset Catalog) specification to structure this metadata. They store the metadata in PGStack, a PostgreSQL extension tailored for STAC, and expose it via a STAC-FastAPI, enabling their Satellite Data Explorer (SDX) interface to leverage the power of PostgreSQL for data aggregation, summarization, filtering, and searching. • Discusses data aggregation, focusing on the Commercial Satellite Data Acquisition Program (CSDAP). • Explains that CSDAP acquires and makes commercial satellite data accessible to researchers. • Highlights the challenge of managing a massive volume of geospatial data (over 30 petabytes) from diverse satellite sensors, requiring effective data discovery. • Emphasizes the crucial role of metadata for enabling data discovery, especially for geospatial data. • Utilizes the STAC (SpatioTemporal Asset Catalog) specification to define the structure of metadata. • Stores STAC metadata in PGStack, a PostgreSQL extension designed for STAC capabilities. • Exposes the metadata via a STAC-FastAPI for interface communication. • Leverages the capabilities of the PostgreSQL database for aggregating and summarizing data, which powers interfaces like the Satellite Data Explorer (SDX).
