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:
- 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 the 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! It has been nearly a year since we featured a Jilin-1 nighttime sample so we are excited to have a new imagery of Athens, Greece to show to our readers. The 92-cm color nighttime Jilin-1 image featured here was collected on February 5, 2021 over Athens, enjoy! (Image Courtesy: CG Satellite).
