How Earth Would Look If All The Ice Melted
 
02:45
We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. This would dramatically reshape the continents and drown many of the world's major cities.

Find elevations to geographic coordonate for a set of points
 
04:14
Find "Missing" Elevations with GPS Visualizer The problem: Sometimes you have geographic data that consists only of latitudes and longitudes, but you want to know the altitudes as well — because, for example, you want to colorize points by height above sea level, or draw a profile of a track. Here are some common reasons why you might have "flat" or incomplete data: Your GPS device does not log altitude, or you had poor satellite reception when you recorded the track. Your GPS device does log altitude, but it's not very accurate. You drew a track using the drawing tools in Google Earth or a similar application, like GPS Visualizer's Sandbox. You have a KML file that came from Google Maps or Google Earth's "driving directions" feature. You created a route in Google Maps and have the URL of that route. You have an NMEA log file that contains only "GPRMC" sentences, not "GPGGA."

mount everest view from space satellite map in Google Earth

mount everest view from satellite map in Google Earth Mount Everest Documentary Mount Everest is Earth's highest mountain. It is located in the Mahalangur mountain range in Nepal and Tibet. Its peak is 8,848 metres (29,029 ft) above sea level. The international border between China (Tibet Autonomous Region) and Nepal runs across Everest's precise summit point. Its massif includes neighbouring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft). In 1856, the Great Trigonometrical Survey of India established the first published height of Everest, then known as Peak XV, at 8,840 m (29,002 ft). The current official height of 8,848 m (29,029 ft) as recognized by China and Nepal was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 2005, China remeasured the height of the mountain and got a result of 8844.43 m. An argument regarding the height between China and Nepal lasted 5 years from 2005 to 2010. China argued it should be measured by its rock height which is 8844 m but Nepal said it should be measured by its snow height 8848 m. In 2010, an agreement was finally reached by both sides that the height of Everest is 8,848 m and Nepal recognizes China's claim that the rock height of Everest is 8,844 m. In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. As there appeared to be several different local names, Waugh chose to name the mountain after his predecessor in the post, Sir George Everest, despite George Everest's objections. Mount Everest attracts many climbers, some of them highly experienced mountaineers. There are two main climbing routes: one approaching the summit from the southeast in Nepal (known as the standard route) and the other from the north in Tibet, China. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, wind as well as significant objective hazards from avalanches and the Khumbu Icefall. As of 2016, there are well over 200 corpses still on the mountain, with some of them even serving as landmarks. The first recorded efforts to reach Everest's summit were made by British mountaineers. With Nepal not allowing foreigners into the country at the time, the British made several attempts on the north ridge route from the Tibetan side. After the first reconnaissance expedition by the British in 1921 reached 7,000 m (22,970 ft) on the North Col, the 1922 expedition pushed the North ridge route up to 8,320 m (27,300 ft) marking the first time a human had climbed above 8,000 m (26,247 ft). Tragedy struck on the descent from the North col when seven porters were killed in an avalanche. The 1924 expedition resulted in the greatest mystery on Everest to this day: George Mallory and Andrew Irvine made a final summit attempt on 8 June but never returned, sparking debate as to whether they were the first to reach the top. They had been spotted high on the mountain that day but disappeared in the clouds, never to be seen again, until Mallory's body was found in 1999 at 8,155 m (26,755 ft) on the North face. Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953 using the southeast ridge route. Tenzing had reached 8,595 m (28,199 ft) the previous year as a member of the 1952 Swiss expedition. The Chinese mountaineering team of Wang Fuzhou, Gonpo and Qu Yinhua made the first reported ascent of the peak from the North Ridge on 25 May 1960.

http://gallery.usgs.gov/videos/567 The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS National 3D Elevation Program (3DEP). The NED provides seamless raster elevation data of the conterminous United States, Alaska, Hawaii, and the island territories. The NED is derived from diverse source data sets that are processed to a specification with a consistent resolution, coordinate system, elevation units, and horizontal and vertical datums. The NED is the logical result of the maturation of the long-standing USGS elevation program, which for many years concentrated on production of topographic map quadrangle-based digital elevation models. The NED serves as the elevation layer of The National Map, and provides basic elevation information for earth science studies and mapping applications in the United States. The NED is a multi-resolution dataset that is updated bimonthly to integrate newly available, improved elevation source data. NED data are available nationally at grid spacings of 1 arc-second (approximately 30 meters) for the conterminous United States, and at 1/3 and 1/9 arc-seconds (approximately 10 and 3 meters, respectively) for parts of the United States. Quality Level 3 and higher lidar point cloud are also available in the public domain for download when they are the source of new NED DEMs. Most of the NED for Alaska is available at 2-arc-second (about 60 meters) grid spacing, where only lower resolution source data exist. Part of Alaska is available at the 1/3-arc-second resolution, and plans are in development for a significant upgrade in elevation data coverage of the State over the next 5 years. Specifications for the NED include the following: - Coordinate system: Geographic (decimal degrees of latitude and longitude), - Horizontal datum: North American Datum of 1983 (NAD 83), - Vertical datum: North American Vertical Datum of 1988 (NAVD 88) over the conterminous United States and varies in other areas, and - Elevation units: Decimal meters.

Find the Topography of Any Property in the World
 
07:42
http://REtipster.com/?p=2591 If you're buying vacant land, one of the things you should be researching is the elevation and topography of the property. Here is a quick tutorial on how to get some perspective with Google Earth. Download the software for free at http://google.com/earth There are many, MANY places in the world that have unpredictable elevations, cliffs, mountains, valleys, ravines and more. In many cases, the topography of the land can have a huge impact on the build-ability of a property. For the same reasons you can't build a house on vertical cliff, you should be doing some preliminary research to find out where your property is located and what the lay of the land is. One of the best ways to do this is with using Google Earth (which is free). You can download the software, search for your property (using the address or coordinates) and zoom in using your mouse buttons along with the control and shift keys on your keyboard. This will allow you to tilt the earth on its side so you can see precisely where all the hills and valleys are in the area. This software has given me a crucial perspective on dozens of the vacant land properties I've purchased.

Elevation - Video Learning - WizScience.com
 
02:04
The "elevation" of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface . Elevation, or "geometric height", is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Less commonly, elevation is measured using the center of the Earth as the reference point. Due to equatorial bulge, there is debate as to which of the summits of Mt. Everest or Chimborazo is at the higher elevation, as the Chimborazo summit is further from the Earth's center, while the Mt. Everest summit is higher above mean sea level. A topographical map is the main type of map used to depict elevation, often through use of contour lines. In a Geographic Information System , digital elevation models are commonly used to represent the surface of a place, through a raster dataset of elevations. Digital terrain models are another way to represent terrain in GIS. The elevation of a mountain usually refers to its summit. The elevation of a hill also refers to the summit. A valley's elevation is "usually" taken from the lowest point, but is often taken all over the valley. This map is derived from GTOPO30 data that describes the elevation of Earth's terrain at intervals of 30 arcseconds . It uses color and shading instead of contour lines to indicate elevation.

Use Bathymetric Maps To Catch More Fish

Learn how anglers use bathymetric maps to catch more fish. Subscribe: http://bit.ly/2jwNfv0 More ice fishing tutorials: http://bit.ly/2ucA3CT If you haven’t seen a bathymetric map before, they’re the submerged equivalent of a topographic map. While the lines, known as contours, of a topographic map show elevations above sea level, the contours of Bathymetric maps show the water depth and what the terrain is like beneath the water’s surface. To read a bathymetric map, just look at the space between contours. The closer the contours, the steeper the slope of the underwater terrain. Conversely, contours spaced further apart indicate landscape features with a more gradual slope. Now let’s take a look at how to read a bathymetric map to catch more fish. 0:41 First, use the bathymetric map to identify habitat features that are more likely to hold fish. 1:07 Second, you can use a bathymetric map to find depths where the species you’re targeting are most likely to be. 1:20 Third, if you have a fishing hole where the fishing is always good, then you can use bathymetric maps to identify other potentially productive areas to fish.
Wilderness Navigation #12 - Contours & Elevation
 
07:14
This video is the best explanation you'll find on YouTube about how contour lines show elevation on topographic maps. Learn definitions and examples of contour lines, index contours, and contour interval, and try your hand at determining elevations and calculating contour interval. This video is part of a series on wilderness navigation and orienteering. See the complete series on our YouTube channel, or at our website, www.croc.org When looking at elevation and contours, there are three key terms we need understand. The contour line, the contour interval, and index contour. Let's start with the contour line. Imagine you’re on a small island in the ocean. The high point of your island is about 35 feet, and it's a few hundred feet around at the water’s edge. Let's also imagine that you have a really big piece of chalk. Now, imagine yourself walking from sea level up to an elevation of 10 feet. You now walk completely around the island at 10 feet of elevation, drawing a mark every few steps with the chalk. You walk more or less in a circle, and arrive back at your exact starting position in a few minutes. You changed direction, walking north, east, south, and west all around the island, but you stayed on the same 10 foot elevation line the entire time. Now, you walk uphill 10 more feet to the 20 foot elevation, and repeat the previous process. You again walk around the island at the 20 foot contour line, leaving a trail of chalk marks. You repeat this one more time, walking uphill 10 more feet to the 30 foot line, and walking around and marking what little remains of the island at elevation 30 feet. Now, you've drawn three lines. Each loop is 10 feet higher than the preceding one, and all the loops are getting smaller as you get towards the top of the island. A bird’s eye view of your island is on the right, which is a perfect contour map of your island. So, this gives us a definition of a contour line - a continuous line of constant elevation. The second of our three terms is a contour interval. An interval is the elevation difference between each contour line. In our example with the island, the interval was 10 feet. Intervals can be in meters or feet, and can be different on every map. On the left is a small scale map from Canada, with an interval of 50 meters. On the right is a 7 1/2 minute map from the US Geological Survey, with interval of 40 feet. Sometimes the interval is printed right on the map, and sometimes you have to figure it out yourself. Contour intervals are almost always multiples of 5, such as 5, 10, 20, 40 or 80. The interval chosen by the mapmaker depends on how steep the terrain is. Intervals may range from 5 feet in very flat areas, like Florida, to 150 or more feet very steep terrain or in small-scale maps. Usually in mountainous areas, the interval is 40 feet. Now, let's have a look at our third key term, the index contour. Here we see a map of the Emmons Glacier on Mt. Rainier. A little quick math shows us that these lines are 200 feet apart. So, knowing this, we can determine the contour interval if it's not printed on the map. To find the interval, we take the vertical distance between index contours and divide by five. Here, 200 feet divided by 5 gives us a contour interval of 40 feet. Now, let's figure out the elevations for each contour line between 4400 and 4600 feet. First, we need to figure out the contour interval. The contour interval is 40 feet. 200 feet between the marked index contours, divided by 5. We add a 40 feet to 4400, and we have the elevation of the next higher contour line. Again, we add 40 feet on to the previous line, and we get 4480. Add 40 feet onto the previous line, we get 4520. And finally, adding 40 feet onto the previous line, we get our last line of 4560. Once you know what the contour interval is, you can find the elevation of any point on your map. Here's how to do it. What is the elevation of Camp Schurman? First, we need to find the contour interval. 200 feet between the index lines divided by 5 gives us in an interval of 40 feet. What's the contour interval here? The index lines are 50 feet apart. Dividing 50 by 5 gives us an interval of 10 feet. What's the contour interval here? The index lines are 100 feet apart. Dividing 100 by 5 gives us an interval of 20 feet. Summary - 1 - All of the points on a contour line have the same elevation. 2 - Contour lines never cross each other. 3 - Index contour lines are printed in a bold, usually every fifth line. 4 - Some, but not all, index contours have an elevation printed on them. 5 - Dividing the elevation change between index contours by five gives you the contour interval. 6 - The contour interval is the real world change in elevation between each contour line. 7 - Sometimes this is printed on the map, and sometimes you have to figure it out yourself. 8 - When you know the contour interval, you can determine the elevation of any point on your map.

(An Accurate Altitude measurement). An app you always need to measure the pressure and height of buildings above sea level.Use this Altitude measurement tool to measure building heights. Height of buildings from ground level to top floor may be cannot measure with a GPS because of inaccurate altitude units. Question Is possible Measuring my altitude above sea level accurately ? I live in a building which sits very high near the top of a hill. I estimate the ground level of the building to be around 700 feet, I live on the 13th floor, so my altitude is approximately 800 ~ 850 feet. I would like to get an accurate measurement (correct to +- 10 feet). How I did the measurement ? ★ Measure the ground level altitude at a park with digital altitude meter ★ Estimate the height of each floor ★ Using a GPS unit in the flat would produce inaccurate results use digital altitude meter ★ GPS units are inheritly inaccurate at altitude (compared to lateral position) ★ I cannot access other floors other than the one I live ★ I have a good view of the city. By looking at a map, I can accurately calculate my ground-level distance to certain sea-level landmarks. These landmarks are some 5 km away. ★ I would like to minimize the cost of purchasing special equipment.
