EnMAP (Environmental Mapping and Analysis Program) is a high-resolution imaging spectroscopy remote sensing mission that was successfully launched on April 1st, 2022. Equipped with prism-based dual-spectrometer, performs observations in the spectral range between 418.2nm 2445.5nm 224 bands high radiometric accuracy stability. products, ground instantaneous field-of-view of 30m×30m at swath width 30km, allow for qualitative quantitative analysis surface variables from frequently consistently...
Imaging spectrometry of non-oceanic aquatic ecosystems has been in development since the late 1980s when first airborne hyperspectral sensors were deployed over lakes. Most water quality management applications were, however, developed using multispectral mid-spatial resolution satellites or coarse spatial ocean colour till now. This situation is about to change with a suite upcoming imaging spectrometers being from experimental International Space Station. We review science developing for...
Vitality loss of trees caused by extreme weather conditions, drought stress or insect infestations, are expected to increase with ongoing climate change. The detection vitality at an early stage is thus vital importance for forestry and forest management minimize ecological economical damage. Remote sensing instruments able detect changes over large areas down the level individual trees. scope our study investigate whether it possible stress-related spectral using hyperspectral sensors. For...
Coastal and inland aquatic ecosystems are of fundamental interest to society economy, given their tight link urbanization economic value creation. These ecosystems, which continuously impacted by natural processes human activities such as litter pollution, including marine plastics, play a significant role in the carbon cycle, they comprise critical habitats for biodiversity. Particularly, improved knowledge distributions plastics is becoming critical. Systematic, high-quality global...
Mapping the submerse vegetation is of prime importance for ecological evaluation an entire lake. Remote sensing techniques are efficient such mapping tasks, if retrieval algorithms and processing methods robust mostly independent from additional ground truth measurements. The Modular Inversion Program (MIP) follows this concept. It a tool designed recovery hydro-biological parameters multi- hyper-spectral remote data. architecture program consists physical inversion schemes that derive...
The downwelling irradiance in water is highly variable due to the focusing and defocusing of sunlight skylight by wave-modulated surface. While time scales intensity variations caused wave are well studied, little known about induced spectral variability. Also, impact sensor depth inclination during measurement on has not been studied much. We have developed a model that relates variance relevant parameters environmental experimental conditions. A dataset from three German lakes was used...
Today, the ground segments of Landsat and Sentinel missions provide a wealth well-calibrated, characterized datasets which are already orthorectified corrected for atmospheric effects. Initiatives such as CEOS Analysis Ready Data (ARD) propose ensure guidelines requirements so that can readily be used, interoperability within between is given. With increasing availability data from operational research-oriented spaceborne hyperspectral sensors EnMAP, DESIS PRISMA, in preparation upcoming...
Forest damage induced by bark beetle attacks can cause major economic losses in forest- ry. Hyperspectral remote sensing data and state of the art very high spatial resolution satellite of- fer a great potential for assessing tree vitality. How- ever, better understanding the effects vitality decrease its impact on spectral behaviour needles is needed. Filling this knowledge gap make significant contribution to improve in- terpretation data. However, it still unclear...
The focus of this analysis is on the early detection forest health changes, specifically that Norway spruce (Picea abies L. Karst.). In analysis, we planned to examine time (degree detection), spectral wavelengths and appropriate method for detecting vitality changes. To accomplish this, a ring-barking experiment with seven subsequent laboratory needle measurements was carried out in 2013 2014 an area southeastern Germany near Altötting. also accompanied by visual crown condition assessment....
EnMAP (Environmental Mapping and Analysis Program, www.enmap.org) is a German, Earth observing, imaging spectroscopy, spaceborne mission planned for launch in 2020. The data products will cover the spectral range from 420 nm to 2450 with sampling distance between 5 12 an expected signal-to-noise-ratio of 400:1 visible near-infrared 180:1 shortwave infrared parts electro-magnetic spectrum. resulting images area 30 km across- track direction ground m. across-track tilt-capability 30° enables...
Moreton Bay is the Australian EO1-Hyperion coastal site used for Cal/Val activities. shows spatial gradients in optical depth, bathymetry, and substrate composition. The turbid humic river inputs, as well open ocean flushing, determine water quality of bay. Lyngbya toxic algae blooms have become a serious environmental health concern. field campaigns, carried out to coincide with Hyperion overpasses, focussed on retrieval inherent properties, apparent reflectance spectra parameters. Spectra...
Airborne hyperspectral data was collected in April 1999 over 16 square kilometres of coastal waters adjacent to the South Australian Bolivar Wastewater Treatment Plant (near Adelaide). Concurrent situ measurements benthic reflectances were collected. A subsequent field-work mission validate image analysis completed February 2000. The aim map substrate type accurately, differentiating species and canopy density, if possible. approach based on coupling radiative transfer models using...
