Celestial data

This project provides several datasets of celestial objects as of the J2000 epoch in GeoJSON and GeoPackage formats.

The original files were provided by the d3-celestial plugin (Frohn 2015) under BSD 3-Clause. The datasets produced by this project consist of the same data provided by the d3-celestial plugin processed with the R package sf (Pebesma 2018) to ensure its validity:

• The spatial data objects are bounded by \([-180, -90, 180, 90]\).

• The coordinates represent J2000 celestial directions in degrees. EPSG:4326 is assigned for compatibility with GIS software. The angles are right ascension and declination.

• All geometries are valid as per ST_IsValid (GEOS 3.9.3).

Distribution

These URLs serve the same minified GeoJSON file from the main branch.

Data

Data are provided in GeoJSON (*.geojson) and GeoPackage (*.gpkg) formats. Additionally, for GeoJSON files a minified version (*.min.geojson) is also provided.

The data source can be found in the corresponding GitHub repo.
