Satellite Image Seychelles

[Jarvarious Hunsaker]

Weathersatellite images (Seychelles) show the cloud cover. New satellite observations become available every 5 to 15 minutes, depending on the location. The images can be animated to produce a minute-by-minute satellite view of the weather. The satellite animation is a great tool to understand weather development and movement of clouds, and is often used by meteorologists for short term weather forecasting. The global satellite composite is generated from 5 different satellites (METEOSAT, GOES-16, GOES-17, HIMAWARI, METEOSAT-IODC) and processed into an Earth-colour image for better readability. The global satellite image has the maximum possible resolution as provided by the satellites, yielding an incredible 500 megapixels for the entire world.

Live satellite imagery is updated every 10 minutes from NOAA GOES, JMA Himawari, and KAI Geo-KOMPSAT geostationary satellites. EUMETSAT Meteosat imagery is updated every 15 minutes. Blue clouds at night represent fog and low-lying clouds. City lights at night are not live.

FSDG released a Seychelles addon for MSFS a few days ago with all the islands, aerials and airports, but I would also like to see Asobo and Bing taking care of these islands asap. Its just a beautiful part of the world. Perfect for island hopping and a cool approach for airliners.

I just checked, it has been updated on Bing since I was there (half a year ago). The airport is now clearly visible. There are still some wispy clouds on the island and the sat view is still cloudy, but it should be possible now to add the airport.

It will look weird though, the transition from sat to aerial view is a complete mismatch

The mosaic of satellite and aerial photographs you can see in Google Maps and Google Earth is sourced from many different providers, including state agencies, geological survey organizations and commercial imagery providers. These images are taken on different dates and under different lighting and weather conditions.

In the coastal waters across much of our planet are meadows of seagrass that are vital to the health of our ocean. These marine flowering plants are critical habitat for a multitude of fish, invertebrates such as crabs and scallops, and other species. Juvenile fish use seagrass as nursery areas, while animals such as turtles and dugongs visit the meadows to feed.

In the first phase of the project, researchers collect countrywide satellite images of the ocean. These images show the presence of seagrass, along with other ocean habitats, such as coral reefs. Because cloud cover and water clarity can affect the quality of the satellite imagery, field data is also collected to differentiate the images.

Researchers collect seagrass data throughout Seychelles, gathering information on the different species and density of seagrass, and taking soil core samples to estimate the carbon stored beneath the meadows.

The satellite images and field data are analyzed and used to produce a high-accuracy, field-validated map of seagrass distribution and extent. The soil cores are analyzed for their carbon content and used to generate a first-time estimate of carbon stock for seagrass meadows in the country.

This scientific information on the distribution of seagrass and its associated carbon stock gives policymakers the information they need to include the protection of seagrass in their NDCs as a nature-based solution to climate change.

Tropical Cyclone FANTALA formed over the south-western Indian Ocean on 11 April. It then moved west, intensifying. It passed near Farquhar Atoll (Seychelles) on 17 April at 6.00 UTC with max. sustained wind speed of 241 km/h and on 19 April at 18.00 UTC with max. sustained wind speed of 157 km/h, causing widespread damage. On 21 April at 6.00 UTC its centre was located approx. 230 km southwest of the Agalega islands (Mauritius) and 640 km northeast of Madagascar and it had max. sustained wind speed of 167 km/h.

Significant damages were reported on Farquhar island on Monday 18th April after FANTALA made landfall on Sunday evening with winds up to 350km/h. No fatalities have been reported but preliminary reports indicated that almost all of the buildings on the island have been damaged or flattened by the storm's powerful winds, except for only four cyclone-proof facilities located on the island. On Wednesday 20th April Seychelles authorities declared Farquhar islands as disaster areas.

On 19th April 2016, UNITAR/UNOSAT has triggered the International Charter on Space and Major Disasters on behalf of the UN Resident Coordinator Office (RCO - Seychelles &Mauritius) to support with satellite damage analysis on going emergency response operations within cyclone most affected areas in Farquhar Atoll.

Hereafter a summary of satellite based analysis undertaken by UNITAR-UNOSAT using post disaster satellite image acquired on 22nd April 2016. The extent of damage is categorized into three main levels/classes: Destroyed, Severe Damage and Moderate Damage.

Important Note: Total number of affected buildings reported as well estimates of different level of building damages may have been underestimated. This is a preliminary analysis & has not yet been validated in the field.

Dr. Rowlands research examines how earth observation data, such as satellite imagery, can be best harnessed to the needs of ecology, conservation, and management. This work includes image and spatial analysis, field monitoring and survey, as well as mathematical modelling to quantify and conserve marine habitats, estimate marine carbon stocks (Blue Carbon), as well as fisheries applications. His work spans tropical and temperate regions of the world, in coastal and oceanic settings and draws on satellite, airborne and vessel-borne sensors.

Her research harmonises marine geospatial data management with innovative field research methods and seeks to collaborate across multiple sectors to benefit the environment and local communities. Her background spans marine ecological fieldwork in tropical and temperate locations as well as data management to inform government policies that drive marine resource management.

Dr Traganos manages the R&D within the Global Seagrass Watch technology transfer project of DLR. This work merges modern Earth Observation advances with artificial intelligence, ecological modelling, and field data to enhance spatially-explicit knowledge and insights pertinent to global nature-based solutions like seagrass ecosystems. His expertise lies in the development of monitoring algorithms for temperate and tropical coastal ecosystems from coastline to bioregional scale, with the aid of active and passive remote sensing, marine geophysics, oceanography, and in situ data.

Dr. Mortimer is an international conservation biologist consultant focusing on sea turtles and tropical coastal and marine ecosystems. She has lived and worked in the outer islands for extended periods totalling several years which enabled her to visit virtually every island in the archipelago. Her primary interests are ecosystem conservation in Seychelles and the wider Western Indian Ocean, and the biology of sea turtles, giant tortoises, and seagrass habitats.

(Seychelles News Agency) - A mapping exercise is being carried out to determine the coverage and carbon storage capacity of Seychelles' seagrass, with a final report expected in June, the lead consultant said recently.

The mapping exercise will demarcate areas around the most populated islands of Mahe, Praslin and La Digue containing seagrass meadows. It will later cover other islands including Desroches, Amirantes, Cosmoledo, Astove, Alphonse and Farquhar.

The Seychelles Conservation and Climate Adaptation Trust (Seyccat) is coordinating the study that began earlier this month in the Seychelles' waters together. The study is being done in collaboration with the University of Seychelles, the Island Conservation Society (ICS) the German Aerospace Centre and the University of Oxford.

Mortimer said that the information will be useful, although it is coming in later than planned "because science is a process, Seychelles has expressed an interest in this, it has expressed commitment to protect seagrass and this study is providing more quantified basis on which to base its policies. The process is going to be going on for decades, it's not only for one year."

Ground truthing is the part of the study whereby the researchers take pictures of the seabed while their GPS is being followed to ensure that the satellite imagery corresponds to what is actually found on the seabed for the given coordinates.

An exercise held earlier this year to name the species has been completed and Mortimer said that they have been working with the Creole Institute to ensure that the names are included in the Creole language dictionary.
