The Environmental Mapping and Analysis Program (EnMAP) is a German hyperspectral satellite mission that aims at monitoring and characterising the Earth's environment on a global scale. EnMAP measures and models key dynamic processes of Earth’s ecosystems by extracting geochemical, biochemical and biophysical parameters that provide information on the status and evolution of various terrestrial and aquatic ecosystems. The mission’s main objective is to study and decipher coupled environmental processes and to assist and promote the sustainable management of Earth’s resources. This collection includes Level 2A (atmospheric correction over land) products of the mission. For more information, please see the mission website: https://www.enmap.org/mission/

The SkySat constellation is comprised of 21 micro satellites with a size of 60 x 60 x 80 cm. SkySats can be tasked to acquire panchromatic and multispectral images of the Earth in high resolution (up to 50 centimeter) and at sub-daily frequency. They can also capture stereo imagery and video footage for up to 90 seconds. The first SkySat was launched in 2013, whereas higher resolution SkySat-C generation satellites were first launched in 2016. The SkySat constellation is owned and operated by Planet. The SkySat imagery of this collection covers specific test sites. The data has been purchased by the German Space Agency with funds from the Ministry of Economy and is available for Germany-based researchers for scientific use. The data collection is maintained by the German Satellite Data Archive (D-SDA) of DLR’s Earth Observation Center and can be accessed via the EOWEB Geoportal. This collection comprises SkySat Collect products. The Ortho Collect product is created by composing SkySat Ortho Scenes along an imaging strip into segments typically unifying approximately 60 SkySat Ortho Scenes. It includes multispectral (BGRN) as well as the panchromatic (PAN) assets. Radiometric corrections to correct for any sensor artifacts and transformation to top-of-atmosphere radiance are applied. If available, the atmospherically corrected Surface Reflectance layer is included. For more details see: https://assets.planet.com/docs/Planet_Combined_Imagery_Product_Specs_letter_screen.pdf

Indian Remote Sensing satellites (IRS) are a series of Earth Observation satellites, built, launched and maintained by Indian Space Research Organisation. The IRS series provides many remote sensing services to India and international ground stations.

The hyperspectral instrument DESIS (DLR Earth Sensing Imaging Spectrometer) is one of four possible payloads of MUSES (Multi-User System for Earth Sensing), which is mounted on the International Space Station (ISS). DLR developed and delivered a Visual/Near-Infrared Imaging Spectrometer to Teledyne Brown Engineering, which was responsible for integrating the instrument. Teledyne Brown designed and constructed, integrated and tested the platform before delivered to NASA. Teledyne Brown collaborates with DLR in several areas, including basic and applied research for use of data. DESIS is operated in the wavelength range from visible through the near infrared and enables precise data acquisition from Earth's surface for applications including fire-detection, change detection, maritime domain awareness, and atmospheric research. The spatial resolution is about 30m on ground. DESIS is sensitive between 400nm and 1000nm with a spectral resolution of about 3.3nm. Experimental products like the Forward Motion Compensation allow to observe the same area on ground by continuous rotating the mirror during forward motion.

The Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument aboard the Terra (EOS AM-1) and Aqua (EOS PM-1) satellites. The MODIS-EU image mosaic is a seamless true color composite of all Terra and Acqua passes received at DLR during a single day. Daily and Near Real Time (NRT) products are available. For the composite, MODIS channels 1, 4, 3 are used. The channels are re-projected, radiometrically enhanced, and seamlessly stitched to obtain a visually appealing result. Terra passes from north to south across the equator in the morning, while Aqua passes the equator south to north in the afternoon. Both MODIS instruments are viewing the entire Earth surface every 1 to 2 days, acquiring data in 36 spectral bands.

Indian Remote Sensing satellites (IRS) are a series of Earth Observation satellites, built, launched and maintained by Indian Space Research Organisation. The IRS series provides many remote sensing services to India and international ground stations. With 5 m resolution and products covering areas up to 70 km x 70 km IRS PAN data provide a cost effective solution for mapping tasks up to 1:25'000 scale.

The RapidEye Earth observation system comprised five satellites equipped with high-resolution optical sensors. Co-funded by the German Federal Government, the fleet of satellites was launched from the Baikonur cosmodrome in Kazakhstan in 2008. RapidEye is owned by Planet Labs, Inc.. It has been operated by Planet Labs Germany GmbH until the constellation was retired in March 2020. With all 5 satellites arranged in one orbit the RapidEye constellation was capable of taking images of the Earth's surface at high repeat rates with a maximum of 5 million km² per day. With a spatial resolution of 6.5m the 5-band sensors onboard the RapidEye satellites operated in the visible and near-infrared portions of the electromagnetic spectrum.

The data collection is maintained by the German Satellite Data Archive (D-SDA) of DLR’s Earth Observation Center and can be accessed via the EOWEB Geoportal. The RapidEye Basic Scene (L1B) product is radiometrically- and sensor-corrected, providing imagery as seen from the spacecraft without correction for any geometric distortions inherent in the imaging process, and is not mapped to a cartographic projection. The imagery data is accompanied by all spacecraft telemetry necessary for the processing of the data into a geo-corrected form.

The PlanetScope satellite constellation, called ‘Flock’, consists of multiple launches of groups of individual Dove satellites into a 400 km orbit. Some of them were launched from the ISS. Therefore, on-orbit capacity is constantly improving in capability or quantity. Each Dove satellite is a CubeSat with a size of 10 x 10 x 34 cm. The complete PlanetScope constellation of approximately 130 satellites is able to image the entire land surface of the Earth every day, equating to a daily collection capacity of 200 million km². In 2014 the first Dove satellites started operationally acquiring images from the earth’s surface. The optical sensors mounted on the individual Dove satellites operate in the visual and near-infrared parts of the electromagnetic spectrum with a spatial resolution between 3 and 5 meters. A third generation of PlanetScope sensors (known as SuperDove or PSB.SD) is currently in orbit and is producing limited quantities of imagery with 5 spectral bands (BGRNIR + Red Edge). These satellites have the potential to produce imagery with 8 separate spectral bands. The PlanetScope data of this collection has been purchased by the German Space Agency with funds from the Ministry of Economy and is available for Germany-based researchers for scientific use. The data collection is maintained by the German Satellite Data Archive (D-SDA) of DLR’s Earth Observation Center and can be accessed via the EOWEB Geoportal. This collection comprises PlanetScope L1B Basic Scene 3-band natural color RGB products. The PlanetScope Basic Scene product is a Scaled Top of Atmosphere Radiance (at sensor) and sensor corrected product, providing imagery as seen from the spacecraft without correction for any geometric distortions inherent in the imaging process. It has a scene-based framing, and is not mapped to a cartographic projection.

This collection contains airborne hyperspectral imagery acquired by the EOC user service OpAiRS. The data was recorded with the airborne DLR EnMAP simulator, which contains two HySpex cameras manufactured by the Norwegian Company NEO. The survey has been conducted within the scope of the “Data Pool Initiative for the Bohemian Forest Ecosystem”. It covers parts of the Bohemian forest, mainly the Bavarian Forest National Park. The data are made available as orthorectified ground reflectance.
