From car-free neighbourhoods to a risk analysis of emissions from new neighbourhoods; engineering offices also have to deal with air quality. Environmental impact assessment (EIA) is now mandatory in the preparation of certain plans. With satellite data, Caeli provides insight into the average concentrations of gas in a living environment. This makes it possible to calculate whether the ambient air quality complies with certain limit values. It can also be used to substantiate an environmental impact assessment. Caeli's accurate data also makes it possible to carry out risk analyses, monitor air quality and gain insight into local sources of pollution. Based on this knowledge, advice can be given on, for example, environmental permits. The satellite data provided by Caeli are displayed on a map, giving you an immediate insight into the air quality, without the need for specific knowledge.
