Level curves and contour lines-Contour lines from Google Earth in 3 steps This article explains how to generate contour lines from the Google Earth digital model For this we will use a plugin for AutoCAD Step 1 Display the area where we want to obtain the Google Earth digital model Step 2 Import the digital model Using AutoCAD, having the PlexEarth Addins installedWith the builtin function contour(x,y,z) of octave one can draw level curves where z remains constant My question is how to draw contour lines on axis x or axis y?

The projection of the contour line at height c into the xyplane is called the level curve at level c Thus a level curve is a plane curve Since the level curves of a function are implicitly defined plane curves, they can be drawn with the use of implicitplot But aSo a level curve is the set of all realvalued solutions of an equation in two variables x 1 and x 2Put simply, contour lines mark points of equal elevation on a map If you trace the length of a line with your finger, each point you touch is the same height above sea level If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down
See the latter for theirAny markers defined by style are ignoredLevel curves and contour plots are another way of visualizing functions of two variables If you have seen a topographic map then you have seen a contour plot Example To illustrate this we first draw the graph of z = x2 y2 On this graph we draw contours, which are curves at a fixed height z = constant For example the curve at height z = 1 is the circle x2 y2 = 1 On the graph we have
As you said, this equation represents a circle with radius ln (C 1) Plots of these curves for select C (for example, plots of concentric circles with radius ln (C 1) for C = 0, 1, 2, 3) are the plots of the level curvesLEVEL CURVES The level curves (or contour lines) of a surface are paths along which the values of z = f(x,y) are constant;Ie the level curves of a function are simply the traces of that function in various planes z = a, projected onto the xy plane The example shown below is the surface Examine the level curves of the function Sliding the slider will vary a from a = 1 to a = 1

Plot level curves (contour lines) of the matrix z, using the contour matrix c computed by contourc from the same arguments;Uploaded By mahinmonsoor123 Pages 171 This preview shows page 56Then the projection of the set of level curves of $f$ onto the $xy$plane is called the Contour Plot or Contour Map of $f$ When we depict a contour plot of a two variable function, it is important to note that it is impossibly to place all the level curves of $z = f(x, y)$ onto the $xy$ plane, and so we often choose specific level curves

Contour Lines Or Level Curves
The implementations to extract lines and curves from contours that I know about are proprietary, and are used as the basis for some patternmatching algorithms If @YvesDaoust doesn't know of an algorithm, then that's a good indication you won't find one easilySee the latter for their interpretation The appearance of contour lines can be defined with a line style style in the same manner as plot Only line style and color are used;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

I had a go at importing 10 metre contour lines for the whole of Eurasia into PostGIS latitudes of 0 46 degrees North required about 110 gig of disk space for the Postgres table and amounted to around 105 million contour lines (At this point before I ran out of space) the SRTM3 data set extends up to 60 degrees North)The graph above may have reminded you of something – a contour (or topographical) map of a landscape Essentially the level sets are the contour lines on a map of a surface This video shows the solution of 3Dgraphs using level curves and contour linesByFaculty of Electrical and Electronic Engineering (FKEE)Universiti Tun Husse
