Ocean dynamic topography (sea level) and drifter tracks
 
01:42
Video showing ocean dynamic topography (sea level) from 1993 to 2012, with drifter tracks superimposed (the dot is the drifter, the tail shows where it has been recently). The drifters follow the flow at about 15 m depth. The fact that they drift along the sea level contours shows that the ocean is close to geostrophic balance - the pressure gradient force is pushing from high to low pressure, but this is balanced by the Coriolis force, an effect of the Earth's rotation, which is proportional to speed and acts to the right of the velocity in the northern hemisphere (left in the south). The effect is that the water flows with high sea level to its right (north) or left (south), for currents persisting for longer than a few days.

How To Create a Contour Map Effect with Photoshop & Illustrator
 
05:15
Today we're going to combine the powers of Adobe Photoshop and Adobe Illustrator to create a contour map effect, you know the ones with loads of lines that show the topography of the landscape. We'll use Photoshop's filters to produce the basic contour map effect, then we'll bring it into Illustrator to vectorize it, then customise the paths to add various line weights and styles.

Site Engineering for Landscape Architects: Contours, Forms, Interpolation, and Slope
 
04:59
A clear understanding of what a contour represents is fundamental to the grading design process. Technically defined, a contour is an imaginary line that connects all points of equal elevation above or below a fixed reference plane or datum. This datum may be mean sea level or a locally established benchmark. A contour line is the graphic representation of a contour on a plan or map. In order to make informed design decisions as well as to execute construction drawings accurately, landscape architects require topographic data for all site development projects. This course discusses the concept of contour lines and delineates a baseline of common contour signatures. The course expands on these concepts with explanations of interpolation and slope formulas and examples of their applications. This course also introduces the basic mathematical equations associated with plotting and manipulating contour lines.

Use Bathymetric Maps To Catch More Fish
 
02:09
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.

A "contour line" of a function of two variables is a curve along which the function has a constant value. It is a cross-section of the three-dimensional graph of the function "f" parallel to the "x", "y" plane. In cartography, a contour line joins points of equal elevation above a given level, such as mean sea level. A "contour map" is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes. The "contour interval" of a contour map is the difference in elevation between successive contour lines. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the gradient is large: the variation is steep. A level set is a generalization of a contour line for functions of any number of variables. Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real or hypothetical surface with one or more horizontal planes. The configuration of these contours allows map readers to infer relative gradient of a parameter and estimate that parameter at specific places. Contour lines may be either traced on a visible three-dimensional model of the surface, as when a photogrammetrist viewing a stereo-model plots elevation contours, or interpolated from estimated surface elevations, as when a computer program threads contours through a network of observation points of area centroids. In the latter case, the method of interpolation affects the reliability of individual isolines and their portrayal of slope, pits and peaks.

Revit 2015 Tutorial Creating Topography with the Toposurface Tool | Black Spectacles
 
06:04
View the entire course: Revit 2015 Basics- Conceptual & Schematic Design https://blackspectacles.com/courses/revit-2015-basics-conceptual-and-schematic-design Let's get into the modeling aspects of this. The project that we're building today, of course, is the Case House, also known as the Stahl House, Number 22 in Los Angeles, and I did not have any topography information other than just Google Earth and doing a little bit of research. So I went ahead and built the topography of what I sort of think it is in Los Angeles. So this is the topography as you can see right here and I have also built some what are called, "Pads" which are essentially the foundation or the flat pad for where the building is going to be built. Now, the reason I went ahead and did this ahead of time and not part of the class is because this can be a very tedious process to build. You're going to go to "Massing & Site" and on the "Massing & Site" tab, there is this "Toposurface" button. You click on that and it goes into what's known as a "Sketch Mode" and these are all of the buttons. You can see that this tab on the ribbon is kind of a teal color, that color indicates that it's called a "Context Menu" which means it only appears when you are in the "Toposurface Edit Mode" and these two buttons right here is an indication that you are in an "Edit Mode." So this is "Finish Edit Mode" or this is "Cancel" the edit mode. Now, the other thing to keep in mind when you're building a topography is that it always deals with what are called "Absolute Elevation Numbers" or "Elevations Above Sea Level." There are no relative elevation numbers so keep that in mind. I'm going to leave this as zero but obviously your site is going to be higher than zero. So to create a topography from scratch, the way that I built the one for this class, you're going to just simply place points. So if I had just clicks four points here, it's all at layers here or all at elevation zero, if I just click those four points and then say "Finish," this is my topography. If I go to the "3D View," you can see that this is it right here. Now, I'm going to turn on the "Shade Mode" which is this button right here, set it to consistent color, that's just so you can see it a little more clearly. So this is the topography that I created, completely flat. Go back to "Level 1" view. If I click on that topography again and I say "Edit Surface," once again, that only appears when you click on the topography, it goes back into the "Sketch Mode" and I can manipulate these points now and to start to add some contours to this surface. So if I click on those two points or I select those two points, I can go up here and I can change that to "3 feet." And you can see as soon as I change that to three feet, it adds a couple of contour lines. By default, Revit will add a contour line at each foot. Now, you can change that. You can have it do every five feet, every ten feet, whatever you want in terms of how the contours are displayed. That's completely up to you. So this is just changing these two points and what Revit is doing is it's just interpolating between these two points, zero to three, and it's putting the one-foot and the two-foot at equal spacing between those points. But as we all know, contours aren't always equal, so you can place additional points. So if I say "Place Point" and I put a number "1" in there, I can then place that point anywhere on this surface, and I can do something like that. And so now, Revit is interpolating between these two points but now, the distance between these two is set. Now, there's a problem here. You can see that as I add these points, Revit doesn't always want to follow exactly where I'm putting these points. I would like that contour to kind of dip down and go around where those points are but you can see how it takes this shortcut across there. Well, Revit has a tendency to do that. It's one of those things that you just have to kind of deal with and how I deal with it is I add extra point that is ever so slightly higher than those. So I say "1 foot 1" and I place that point right in the middle. Now, sometimes you have to place multiple points but basically, by doing that, it forces the contour to follow the point path that you've created. Now obviously, the more points you put in there, the smoother the line begins to look. This is basically how you create a topography from scratch.

Meteorological Forcing
 
04:01
This is an example of processed meteorological data (pressure, wind speed, wind direction) to be used for an ADCIRC simulation with NWS=6. These data were generated by interpolating discrete data from NOAA/NWS stations in the Gulf of Mexico to a rectangular LAT-LON grid and a constant time increment. The top frame has color contours of mean sea level pressure and vectors indicating wind direction and magnitude (reference vector provided). The symbols indicate the locations of the met stations, and their color denotes their raw, unprocessed value. In this manner, we can evaluate the effects of our interpolation and low-pass filtering scheme on the processed data. The color contours in the lower frame indicate wind speed magnitude.

Sea Level Sinks. AlGoReal CO2 Hoax
 
01:13
Meriveden pinta romahtaa 1,32 metriä vuosisadassa Pohjanlahden alueen maankohoamisen takia. Jonnekin vesi valuu. Minne? Luulisi siellä pinnan nousevan... Hae lisätiedot ja faktat tältä blogisivultani http://wp.me/px1AT-Gs Water is a fluid. Right? When earth surface rise 'higher', water tends to escape lower places. Sea surface north from Scandinavian Kvarken drops 1,32m per 100 yrs, - FOUR FEET 4" - sea escapes / land rises ... States pull hefty levies from landowners from the newly revealed landmass... only from beach landowners (as ground under sea 'belongs' to the STATE) ... taxing from SEA level DROP. AlGoRealism (MSM programmed mass hysteria) has based the immense CO2 taxes on this sea level rise hoax. Taxing all of us from SEA LEVEL RISE. This global tax ending in vat-i-can coffers is possible only via global UN gvmt - papal new world order. This imaginative video's Kvarken -simulation has never been done. Why? Because every University on this Earth is under strict financial CO2-umbilical cord. If somebody tries to simulate and prove how sea levels are falling somewhere, like in Scandinavia, that researcher will find himsel on the 'mile-mfg plant'. Find proof & other details at my site http://wp.me/pwIAV-19 The first illustration containg the current movement e.g. the altitude contours can be found from the Finnish Geological Institute site at www.gtk.fi Other resources are plentiful - although try to minimize the issue into just landrise - never even touch the related Sea Level Drop. Here is just one linky www.absoluteastronomy.com/topics/Kvarken One of the hillaryous details are hidden in polar bear census: "they are on the brink of exctintion" ... err via multiplying. 1950 census was 2500 bears, 2005 census was 25.000. Unbearable. RIGHT!? http://www.kvarkenguide.org/geologien.html Merenkurkku=Kvarken. Katso www.kvarkenguide.org Geologit kertovat että Pohjanlahdesta tuleekin järvi vuonna 2500, alueen nousu tulee olemaan vielä yli 100metriä. Kas tuostahan vesi säikähtää ja pakenee kaukomaiden saarille... The thick ice sheet, which was three kilometres at its thickest, pressed the earth's crust 800 to 1,000 metres downward. When the ice began to melt the crust began to lift to reach its previous position. The land uplift rate in Kvarken is currently 8 to 8.5 mm per year. At this rate, the flat coastal and archipelago landscape noticeably changes during a single generation. Bridges and boathouses wind up on dry land, waterways become shallow, inlets are cut off from the sea and new underwater banks emerge. Scientists expect the land to rise another 100 to 125 metres. In about 2,500 years this will result in a land bridge across the Kvarken strait. The development will be quite different if the greenhouse effect becomes reality, with the level of the sea rising as the polar ice cap begins to melt due to global warming. This scenario would counter the effects of the land uplift. Terranova - Kvarken Nature Centre Terrranova, "the new land", depicts the land uplift, Kvarken's nature and nature conservation areas, and provides information about outdoor activities and nature tourism in the area. Terranova - Kvarken Nature Centre is located in the Ostrobothnian Museum. .

Breaking News  - Sea level fears as more of giant Antarctic glacier...
 
05:02
More of a giant France-sized glacier in Antarctica is floating on the ocean than previously thought, scientists said Tuesday, raising fears it could melt faster as the climate warms and have a dramatic impact on rising sea-levels.The Totten Glacier is one of the fastest-flowing and largest glaciers in Antarctica with scientists keen to keep a close eye on how it melts given the enormous amount of water it could potentially unleash.Using artificially created seismic waves that help scientists see through the ice, researchers have discovered that more of the Totten Glacier floats on the ocean than initially thought.'In some locations we thought were grounded, we detected the ocean below indicating that the glacier is in fact floating,' said Paul Winberry from Central Washington University, who spent the summer in Antarctica studying the Totten.The findings are important because recent studies have shown the Totten Glacier's underbelly is already being eroded by warm, salty sea water flowing hundreds of kilometres inland after passing through underwater 'gateways'.As it does, the portion of the glacier resting on water rather than rock increases, accelerating the pace of disintegration.Winberry said more of the glacier floating on a warming ocean could help explain recent periods of accelerated melting.'It also means the Totten might be more sensitive to climate variations in the future,' he added.Glaciers are huge bodies of dense ice that slowly move down valleys, mountains and slopes under their own weight over many centuries, sculpting the earth below as they go.They hold the vast majority of Earth's fresh water and are the main contributor to rising sea levels when they melt.According to NASA monitoring, between 2002 and 2016, Antarctica lost 125 gigatonnes of ice per year, causing sea levels worldwide to rise by 0.35 millimetres annually.From the air, the contours of Totten Glacier are invisible because the entire Antarctic continent is covered by a seamless, kilometres-thick blanket of snow and ice.That is why scientists are so determined to understand what is happening underneath the glacier, hidden from view.Team leader Ben Galton-Fenzi, from the Australian Antarctic Division, said the Totten Glacier contains enough ice to raise global sea levels by about three metres (9.8 feet) if it all melted.'Since the 1900s the global sea-level has risen by around 20 centimetres and by the end of the century it's projected to rise by up to one metre or more, but this is subject to high uncertainty which is why studying glaciers such as the Totten is important,' he said.'These precise measurements of Totten Glacier are vital to monitoring changes and understanding them in the context of natural variations, and the research is an important step in assessing the potential impact on sea-level under various future scenarios.'Instruments to measure the glacial flow, speed and thickness have been left on the glacier for another 12 months collecting data.

How to view Hillshade and Contours
 
01:47
This video shows what Hillshade and Contours are as well as some examples of what they show. We start off seeing the county in an aerial perspective showing where the Grand River flows through the northern half. When Hill shade is turned on, it shows that at one point you can see that the Grand River actually flowed through the southern half of the county based on elevation changes. We then zoom in to Dewey Hill in Grand haven and turn on Contours which show the topography of the county as feet above sea level. https://gis.miottawa.org/ottawa/geocortex/propertymapping
