Explore how Rasdaman facilitates efficient handling of complex, multi-dimensional climate datasets in Alaska and the Arctic. See its integration with geospatial tools that streamline data access and provide new ways of interacting with climate data.
Global climate models produce complex multidimensional datasets representing climate variables like temperature and precipitation over time and space, often for multiple emissions scenarios. These “data hypercubes” present significant challenges for integration with geospatial tools and infrastructure due to their size and complexity. Traditional databases struggle with these datasets, making storage, querying, and analysis difficult. Specialized technologies are needed to make this data accessible online for geospatial applications.
Rasdaman (short for “raster data manager”) is an open-source, highly scalable database management system designed for handling large-scale multidimensional raster data. Rasdaman supports key geospatial protocols, including the OGC’s WMS, WCS, and WCPS, essential tools for facilitating data queries over multidimensional datasets and visualizing geospatial data in mapping applications to make it accessible to a wider audience.
Our presentation will demonstrate how the Scenarios Network for Alaska and Arctic Planning (SNAP) has successfully integrated Rasdaman into our geospatial data infrastructure. Rasdaman’s WCPS capabilities enable our public API to access multi-terabyte datasets and return web-friendly JSON for integration into various applications. WCPS also makes “computational styles” possible, so that WMS queries can return styled processed subsets of the data hypercube. We’ll show how this works for climate indicators derived from the Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets and other higher dimensional climate datasets.
This platform allows us to produce web tools that access climate data hypercubes in a performant, scalable manner, and to make this climate data accessible to a broader audience. Our goal is to enhance engagement and understanding of climate science among the general public, policymakers, researchers, and indigenous rights-holders in Alaska and the Arctic.
Join us to see how Rasdaman fits into our infrastructure and how it makes managing complex climate data efficient and accessible.
