![GitHub release (latest SemVer)](https://img.shields.io/github/v/release/dieghernan/celestial_data)

This repository contains several datasets in GeoJSON and GeoPackage format of
celestial objects as of J2000 epoch.

The original files were provided on the [d3-celestial
plugin](https://github.com/ofrohn/d3-celestial/) [@frohn2015] under [BSD
3-Clause](https://opensource.org/licenses/BSD-3-Clause). The datasets on this
repository consists on the same data provided on [d3-celestial
plugin](https://github.com/ofrohn/d3-celestial/) processed with the **R**
package **sf** [@pebesma2018] to ensure its validity:

-   The spatial data objects are bounded to $[-180, -90, 180, 90]$.

-   Date is provided on WGS84 - World Geodetic System 1984
    ([EPSG:4326](https://epsg.io/4326)).

-   All geometries valid as per
    [ST_IsValid](https://postgis.net/docs/ST_IsValid.html) (GEOS **3.9.3**).

## Distribution

The data can be accessed from several API endpoints:
