Monoclinic Minerals blue = crystallographic axes red = indicatrix axes The angles of the other two indicatrix axes are described relative to the closest crystallographic axis e.g. Z ^ c = +15° (it’s positive if the indicatrix axis falls within the obtuse angle between a and c axes) and X ^ a = -5 ° (it’s negative ...

Nettet23. sep. 2024 · Tissot’s indicatrix, or ellipse of distortion, is a circle or ellipse that measures and illustrates distortion caused by map projection.It is a concept developed … NettetThe image for the Monkey Saddle that you linked to is drawn using the classical graphical method that Dupin defined. Now, noting that if the second fundamental form is non-vanishing, the "equation" solved by the indicatrix is. κ 1 x 2 + κ 2 y 2 = 1. which is either an ellipse, a hyperbola, or two parallel lines.
Nettetindicatrix would take the form of a prolate spheroid. Hint: this indicatrix is elongated in the direction of the vertical stroke of a plus sign. Figure 3. The uniaxial indicatrix. The … Nettet5. jun. 2024 · Generally speaking, the indicatrix of a Finsler space can be a surface of a rather general form. The Finsler metric tensor induces a Riemannian metric on the indicatrix, converting it into a Riemannian space. For each fixed $ x $ the Finsler metric tensor is Riemannian in the variables $ y $. The pair $ ( M _ {x} ^ {*} , g _ {ij} ( x, y ...
A single indicatrix describes the distortion at a single point. Because distortion varies across a map, generally Tissot's indicatrices are placed across a map to illustrate the spatial change in distortion. A common scheme places them at each intersection of displayed meridians and parallels. Se mer In cartography, a Tissot's indicatrix (Tissot indicatrix, Tissot's ellipse, Tissot ellipse, ellipse of distortion) (plural: "Tissot's indicatrices") is a mathematical contrivance presented by French mathematician Se mer In the adjacent image, ABCD is a circle with unit area defined in a spherical or ellipsoidal model of the Earth, and A′B′C′D′ is the Tissot's indicatrix that results from its projection onto the … Se mer • MacAdam ellipse Se mer • Java applet with interactive projections showing Tissot's indicatrix Se mer Tissot's theory was developed in the context of cartographic analysis. Generally the geometric model represents the Earth, and comes in the form of a sphere or ellipsoid. Tissot's indicatrices illustrate linear, angular, and areal … Se mer Another way to understand and derive Tissot's indicatrix is through the differential geometry of surfaces. This approach lends itself well to modern numerical methods, as the parameters of … Se mer
