    • Earth is known as the “Blue Planet” due to the vast bodies of water that cover its surface. With an over 70% of our planet’s surface covered by water, ocean depths offer basins with an abundance of features, such as underwater plateaus, valleys, mountains and trenches. The average depth of the oceans and seas surrounding the continents is around 3,500 meters and parts deeper than 200 meters are called "deep sea". This visualization reveals Earth’s rich bathymetry, by featuring the ETOPO1 1-Arc Minute Global Relief Model. ETOPO1 integrates land topography and ocean bathymetry and provides complete global coverage between -90° to 90° in latitude and -180° to 180° in longitude. The visualization simulates an incremental drop of 10 meters of the water’s level on Earth’s surface. As time progresses and the oceans drain, it becomes evident that underwater mountain ranges are bigger in size and trenches are deeper in comparison to those on dry land. While water drains quickly closer to continents, it drains slowly in our planet’s deepest trenches. These trenches start to become apparent below 5,000 meters, as the majority of the oceans have been drained of water. In the Atlantic Ocean, there are two trenches that stand out. In the southern hemisphere, the South Sandwich trench is located between South America and Antarctica, while in the northern hemisphere the Puerto Rico trench in the eastern Caribbean is its deepest part. The majority of the world’s deepest trenches though are located in the Pacific Ocean. In the southern hemisphere, the Peru-Chile or Atacama trench is located off the coast of Peru and the Tonga Trench in the south-west Pacific Ocean between New Zealand and Tonga. In the northern hemisphere, the Philippines Trench is located east of the Philippines, and in the northwest Pacific Ocean we can see a range of trenches starting from the north, such as the Kuril-Kamchatka, and moving to the south all the way to Mariana’s trench that drains last. It is worth recalling that the altitude values of ETOPO1 range between 8,333 meters (topography) and -10,833 meters (bathymetry). This range of altitude values reflects the limitations of the visualization, since Challenger Deep - the Earth’s deepest point located at Mariana's trench - has been measured to a maximum depth of 10,910 meters and Mount Everest the highest peak above mean sea level is at 8,848 meters. In this visualization the vertically exaggerated by 60x ETOPO1 relief model, utilizes a gray-brown divergent colormap to separate the bathymetry from topography. The bathymetry is mapped to brownish hues (tan/shallow to brown/deep) and the dry land to greys (dark gray/low to white/high). A natural consequence of this mapping is that areas of the highest altitude are mapped to whitish hues, as they are almost always covered in snow. Furthermore, in an effort to help viewer’s eyes detect surface details that would otherwise be unnoticeable, the topography and bathymetry have been rendered with ambient occlusion - a shadowing technique that in this particular visualization darkens features and regions that present changes in altitude, such as mountains, ocean crevices and trenches. download: https://svs.gsfc.nasa.gov/vis/a000000/a004800/a004823/OceanDrain_Colorbar_1920x1080_30fps.mp4 https://svs.gsfc.nasa.gov/vis/a000000/a004800/a004823/OceanDrain_1920x1080_30fps.mp4   source: https://svs.gsfc.nasa.gov/4823  
    • Hello everyone,  a nice plugin for Chrome or Firefox which shows a new satellite imagery (from Google Earth) every time you open a new Tab..  Experience a beautiful image from Google Earth every time you open a new tab. Earth View displays a beautiful landscape from Google Earth every time you open a new tab. Chrome : https://chrome.google.com/webstore/detail/earth-view-from-google-ea/bhloflhklmhfpedakmangadcdofhnnoh?hl=en Firefox : https://addons.mozilla.org/en-US/firefox/addon/earth-view-from-google/  
    • what that tools, using 9.3.1 is like using windows 2000 interface, even more not like XP experience nor Windows 7
    • is there any chance to get the software? thanks 
    • These are some of the most common geographic misconceptions that are both surprising and surprisingly hard to correct. https://www.nationalgeographic.com/culture/2018/11/all-over-the-map-mental-mapping-misconceptions/
