Launched and operated by CG Satellite, meet Jilin-1, the only world’s only high-resolution satellite constellation collecting color nighttime imagery. Offered at 92-centimeter (cm) resolution, nighttime imagery from Jilin-1 is the ideal solution for a plethora of problems only now solvable by this satellite constellation, including:
These 92-cm color Jilin-1 nighttime images come courtesy of CG Satellite.- Light pollution studies
- Population estimates
- Detection of burnt out street and building lights
- Measurement of short-term disturbances in power delivery caused by natural disasters
- Monitoring of illegal nighttime fishing
- Modeling of anthropogenic carbon emissions
In this series focused on 92-cm nighttime satellite imagery from Jilin-1, we feature new samples as they become available to us, as well nighttime data is pretty amazing! In the last edition of this sporadic series we were in Paris, and for the December edition we stay in Europe with a quick jaunt south to Seville, Spain. And what makes this sample extra special is that it was collected by one of three new nighttime Jilin-1 satellites, GF03C, launched in September 2020 – in fact this is the first sample we have seen from the three new birds! This 92-cm Jilin-1 sample was collected on September 30th and in these three nighttime images we are particularly impressed with the new satellite’s ability to resolve patterns of small lights.
