Community & ecosystem
Open, reproducible work that uses the HEALPix DGGS tools — including contributions beyond the core consortium. Contributions are welcome.
Examples & applications
Reproducible, healpix-geo-based work on real Earth Observation and environmental science — applications, replications and benchmarks, each tagged by kind.
earthcare-dggs
Converting ESA EarthCARE L2 satellite data (MSI / ATLID / CPR profiles) to HEALPix DGGS-Zarr with healpix-geo and xdggs.
white-shark-geolocation-light
Open pangeo-fish HMM geolocation of juvenile white sharks on a HEALPix-NESTED grid with healpix-geo and xdggs, given the same light + SST inputs as proprietary GPE3 — extending an independent open-data replication of the method.
weatherxbiodiversity-projection
Projecting Iberian bumblebee extirpation risk under Destination Earth Climate DT (SSP3-7.0) on equal-area HEALPix (depth 6, WGS84) via healpix-geo; a resolution-doubled nside=128 variant extends it.
healpix_geo_replication_2026
Replicating the Law & Ardo (2024) DGGS land-use mapping benchmarks on HEALPix via healpix-geo, with a spherical-vs-WGS84-ellipsoid comparison — the ellipsoidal companion to an H3-based replication (dggs_replication_2026).
sdm-scale-replication
FORRT replication of Hurlbert & Jetz (2007): how species-richness hotspots shift with grid resolution, on GBIF data indexed to multi-resolution HEALPix-NESTED cells with healpix-geo. Root of a three-study hotspot-bias chain.
fiesta-scattering-sst-healpix-geo
Does the WGS84 ellipsoid matter for SST gap-filling? A sphere-vs-ellipsoid HEALPix comparison for scattering-transform reconstruction of Copernicus Marine SST, via healpix-resample / healpix-geo.
healpix-analyse-s2-powerspectrum
The angular power spectrum of a Sentinel-2 scene on equal-area HEALPix — put EO data on the WGS84 grid with healpix-geo, analyse it with the differentiable (PyTorch) healpix-analyse.

Built something with the HEALPix DGGS tools — an example, a replication, a dataset? Adding it to this page is a few lines of text. The step-by-step guide shows exactly how, with a copy-paste template.
