WaltR is a specialist in remote sensing. We exploit EO expertise, as well as a patented space technology from CNES that enable the precise mapping of gaseous and particulate pollutant emissions from a city, an industrial site, intensive agriculture activities, airport or port infrastructures. The aim is to provide easy and reliable access to GHGs and air pollutants emission info to enable data-driven actions to improve air quality and mitigate climate change. The processing of immense volumes of satellite data requires highly effective and resource-efficient programming. WaltR services are designed to be commercial, thus, it doesn’t just solve a problem, or invent a method, it does it cost -efficient, and economically viable. To do so, there is a need and an execution of high-end processing, programming, as well as infrastructure management and architecture. The result is, all information being timely, accurate, and “under-one-roof”.
