Celestial data

#astronomy #celestial #csv #maps

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.
