Bluesky Aerial Maps Help Assess Risk of Flash Floods

Aerial photography from Bluesky is being used to identify changes in sediment movement in upland river courses, to help assess the risk of flash flooding. In research centred on the English Lake District National Park, the imagery is helping map region-wide river erosion and sedimentation patterns. Using a Geographical Information System (GIS), the aerial maps, dating from 2003 and 2009, alongside older aerial photographs and historic Ordnance Survey maps, are being used to understand river channel change from 1850 to the present day. “Upland rivers experience high rates of erosion and sediment transfer and are highly susceptible to changes in their...

Global Water Quality Monitoring Tool Available to Public

The United Nations Education, Scientific and Cultural Organisation (UNESCO) with EOMAP have launched an interactive tool providing access to detailed global water quality indicators from an archive of Earth Observation and satellite data. The portal was developed to support the UN’s International Initiative on Water Quality (IIWQ) of UNESCO’s International Hydrological Programme (IHP), and is the first tool to combine high-resolution global coverage with a range of satellite measurements for monitoring streams, lakes, rivers and coastal waters. The IIWQ Portal includes a functionality to select different time periods dating back over the last three decades. Historic measurements are provided at... (read more)

Monitoring, Mapping, and Modelling Saltmarsh

The UAV Way
Coastal and estuarine saltmarsh has long been recognised as having key physical, ecological, and recreational value, acting as sediment and nutrient traps and as natural coastal protection structures functioning as protective buffers between the land and sea. Additionally, they are important areas for shelter, feeding and breeding of diverse forms of wildlife (Doody, 2007). Recent work suggests that saltmarshes are particularly good for demonstrating how the coast can change in response to environmental influences, including relative sea level rise. The pace of current Scottish relative sea level rise (Rennie and Hansom, 2011) may lead to inundation of coastal saltmarsh, with... (read more)

Landsat 8 Celebrates Five Years in Orbit

The Landsat 8 Earth-observing satellite has marked being five years in orbit. In that time, it has racked up 26,500 orbits around the planet, 1.1 million "scene" captures, and an abundance of images that represents 16% of all the continuous observations in the 45 year Landsat archive. Landsat 8, which makes global measurements of Earth's land surface, strengthened the program's role as a cornerstone among the growing number of government and commercial programs that capture imagery of Earth from space. The global coverage and faster data acquisition rates are enabling significant research and opening up new ways in which scientists,... (read more)

Unique 3D Habitat Map of the Great Barrier Reef

International aquatic remote sensing company EOMAP recently showcased its unique contribution to the world's first 3D habitat map of the Great Barrier Reef (GBR) at the International Forum on Satellite-Derived Bathymetry (SDB Day 2019) in Australia. The mapping project, titled ‘3D live habitats for the full extent of the Great Barrier Reef’, will for the first time provide maps of the predicted coral types and underwater landscape for the more than 3,000 reefs within the 350,000 square kilometres of the GBR. EOMAP’s cutting-edge technology provides essential data for this revolutionary project, in which the University of Queensland (UQ), Great Barrier Reef Marine Park... (read more)
