speciesgrids: build pipeline and documentation for a gridded dataset of marine species occurrence

speciesgrids is a cloud-optimized gridded dataset of WoRMS-aligned marine species distributions, built from the OBIS and GBIF occurrence snapshots. The dataset is available as GeoParquet and the build code supports H3 and Geohash grid output.

This archive contains the code and documentation behind the dataset: the Python build pipeline, a web viewer, and example notebooks in Python and R. It does not contain the dataset itself. The dataset (H3 resolution 7, about 600 MB) is openly available at s3://obis-products/speciesgrids/h3_7/ and is licensed under CC BY-NC 4.0, following the license of its GBIF source data. The code in this archive is licensed under MIT.

Documentation, including data access instructions and a data dictionary, is available at iobis.github.io/speciesgrids.
