Remote sensing first developed in the 1880s when Sir Walther Noel Hartley described the strong UV absorptions between 200 and 300 nm in the atmosphere due to ozone. Developing steadily since then, with particular surges of progress during the two World Wars, remote sensing techniques now contribute to many aspects of life and utilize several regions of the electromagnetic spectrum. The major ones are the UV / Vis / IR (ultraviolet, visible, and near- infrared) region (< 3 μm wavelength) which measure reflected solar energy, and the mid- infrared, thermal-infrared, and microwave regions (> 3 μm wavelength) which measure emitted radiation from the Earth’s surface and atmosphere.
The European Association of Remote Sensing Companies (EARSC) is the European organization which –on a non-profit basis– promotes the use of EO technology and especially the companies in Europe which offer EO-related products and services. We are a membership based organisation with the mission to foster the development of the European EO geo-information services industry.
More information on our activities can be found on this site and in other tools which we develop on behalf of our members. All our on-line information and services can be accessed through the links at the top of this page. Our goal is to provide a rich source of information about the sector and the products on offer; we would welcome your contribution and / or your views via the contact form or via the EO Forum in the EARSC EO Portal.
If your company is based in Europe and is using or delivering EO products and services to customers then why not join us? Whether your objective is to increase awareness, reinforce your products and services, identify new business opportunities, or networking with other players in the sector, we can help.
