A unique insight into the earth at night
NOKTOsat Satelite images
Satellite images in colour for your light pollution, environmental or economical studies.
Noktosat is our product of Radiance Calibrated Nocturnal Multispectral (RGB True Color) Imaging taken from the International Space Station (ISS). Noktosat images are ideal for tracking human activity globally. All of the following fields have at some point benefitted from the use of black and white nocturnal satellite images.
Now, Noktosat offers satellite images in colour that provide far more quality data than what was previously available. Some examples of uses are:
Energy efficiency, Air pollution, bio diversity protection, Illegal fishing, Sky brightness estimation, light pollution, Co2 level estimations
Tracking economic activity, GDP estimation, Poverty assessment, Oil production
Population estimation, Land use, Cultural difference
Safety and security
Civil safety, Monitoring disaster areas
Regulations for light pollution, construction, traffic safety
Cancer research, Mosquito related illnesses
NOKTOsat is a spinoff from the Cities at Night project and resulted from more than 20 years of research in advanced scientific instrumentation and astrophysics. In order to assist in light pollution research carried out by the Complutense University of Madrid, NOKTOsat developed software that produces full radiometric calibrated images. These calibrated images have been essential to research collaborations such as the Cities at Night project involving NASA, ESA and various research institutes.
NOKTOsat images have contributed to internationally acclaimed research that has been published in high impact scientific journals. We are convinced that the knowledge obtained through our calibrated images is valuable to society in general. Therefore, we want our data to be easily accessible to the public.
Furthermore, in order to make future research in the field of light pollution sustainable, part of the profit of this company will go to further research projects focused on understanding the impact of artificial lighting on the environment.
Our images have been used in numerous research studies. Some of them:
Complutense University of Madrid
After an impressive 500 years of research in astronomy carried out by the Complutense University of Madrid, it officially founded the astrophysics department in 1987. Although, light pollution was not considered a serious research field until recently, for five decades it has already been an important parameter when testing potential sites for high altitude observatories. The Complutense very own observatory was planned in the nineteen twenties when light pollution was not an issue. However by the time it was build, light pollution had increased dramatically and with the fast growth of the Madrid metropoly the observatory is now one of the most light polluted observatories in the world. This disadvantage turned into an advantage for our research in light pollution. Since 1994 the observatory has continuously been used for light pollution research. In 2007 we began to research light pollution using satellite images of the earth at night in addition to the sky brightness measurements we were taking on the ground.
Many pioneer programs have been developed during the Complutense´s light pollution research since 1994. For example; the citizen science projects "NixNox" and "Cities at Night", the EU project "Stars4all", the TESS photometer and the REECL (the Spanish network of light pollution studies). In addition to initiating and leading many pioneer programs in the field of light pollution the Complutense university has also participated in some of the most crucial light pollution research in the world such as the new world atlas of artificial light at night and the LONNE network of European researchers in light pollution.
CEGEP of Sherbrooke (GRAPHYCS)
As part of an environmental study Noktosat images were used during the streetlight planning of the city of Montreal.
GFZ German Research Centre for Geosciences
GFZ has been using Noktosat images for research purposes mainly focused on land use and the monitoring of the evolution of light pollution.
IS Global Barcelona Institute for Global Health
IS Global is using NOKTOsat images for epidemiological studies in cancer research.
Universidada De Santiago De Compostela
USC is using NOKTOsat data for advising the regional government of Galicia on light pollution control.
