The detection and repair of methane leaks from fossil fuel production activities have been identified as a key climate change mitigation strategy. In the last years, a number of optical satellite missions with a spatial resolution of 30-m or better have shown potential for the detection of strong methane plumes emitted by point sources, which …
Precise geocoding/orthorectification/co-registration of EO images are pre-requisites for most further data use and applications. These operations require precise, high-quality Ground Control Points (GCPs). The Sentinel for 3D Ground Control Point (Sen3GCP) project, funded via the EO science for society Permanently Open Call mechanism, has been developing a GCPs hub, a dedicated service with several functionalities. …
The objective of the SENTREE (Semi-supervised SENtinel-2 TREE Species Detection) project is to detect tree species in Norwegian production forests by developing deep learning models which will combine high resolution aerial imagery with Sentinel-2 data. A major challenge in utilizing deep learning for tree species detection is the limited amount of training labels and their …
Reflectance of the Earth surface is one of the natural major components affecting climate. Surface interaction with incoming solar radiation and the atmosphere has a substantial impact on the Earth’s energy budget. Moreover, the accurate description of the surface reflection is crucial for different atmospheric studies including aerosol and trace gases characterization. One of …
Operational retrievals of trace gas column amounts assume (near) cloud free conditions. However, the large pixel size of the satellite instruments (for example the TROPOspheric Monitoring Instrument on Sentinel 5P, TROPOMI-S5P, is 5.5 km by 3.5 km at nadir) imply that pixels may be contaminated by sub-pixel sized cloud(s). Furthermore, clouds in neighbour pixels may …
LuftBlick Earth Observation Technologies (LuftBlick) and the Royal Belgian Institute for Space Aeronomy (BIRA) propose to develop a novel algorithm to derive ozone profiles from measurements of ground-based passive remote sensing instruments. These are the highlights of our proposed activity: The novel algorithm distinguishes itself in several ways from existing approaches: It uses MAX-DOAS sky …
Scarcity of water resources is today a real issue in some geographic areas. Temperatures have increased by 0,85°C on average between 1880 and 2012 and could reach 4,8°C increase by 2100 compared to the period 1986-2005, according to the latest IPCC report. As one of the consequences, agriculture and viticulture are facing droughts at the …
Optimizing water resources is a real issue in some geographical area. Temperature have increased by 0,85°C on average between 1880 and 2012 and couldreach 4.8°C by 2100 compared to the period from 1986 to 2005, according to the last IPCC report. As a result, agriculture and viticulture are facing an increasing water scarcity at the …
The aim of the activity is to apply super-resolution reconstruction multispectral Sentinel-2 images, using multiple images of the same region, captured at different points in time (MISR, multiple-image super-resolution). This is achieved by adapting recent deep neural networks that were recently proposed for dealing with MISR, to the particularities of Sentinel-2 data. In particular the …
The execution of the construction projects is usually the longest phase in the project life cycle and it typically consumes the most energy and the most resources. Global construction companies cannot be physically present all along the execution phase to control the implementation of the construction on-site. Then, they are used to control advancement only …
