<p>Acabo de actualizar mi dataset sobre contaminación lumínica nocturna global generado con mi herramienta radiance-geojson (<a href="https://codeberg.org/imigueldiaz/radiance-geojson" rel="nofollow" class="ellipsis" title="codeberg.org/imigueldiaz/radiance-geojson"><span class="invisible">https://</span><span class="ellipsis">codeberg.org/imigueldiaz/radia</span><span class="invisible">nce-geojson</span></a>). Contiene archivos JSON (.json.gz) y un dump completo en PostGIS (restaurada ocupa 27GB, con casi 140 millones de puntos georreferenciados), con datos de radiancia, brillo del cielo y clasificación Bortle para 173 países a 0.5 km de resolución. Basado en imágenes VIIRS de Earth Observation Group, Colorado School of Mines.</p><p>Puedes descargarlo gratis desde: <a href="https://archive.org/details/radiance-geojson-data-2025" rel="nofollow" class="ellipsis" title="archive.org/details/radiance-geojson-data-2025"><span class="invisible">https://</span><span class="ellipsis">archive.org/details/radiance-g</span><span class="invisible">eojson-data-2025</span></a></p><p>Ideal para análisis geoespaciales, ambientales y astronómicos, en mi caso lo usaré para astrofotografía si me da la vida.
