Coordinate charts are mathematical objects of topological manifolds, and they have multiple applications in theoretical and applied mathematics. When a differentiable structure and a metric are defined, greater structure exists, and this allows the definition of constructs such as integration and geodesics .
Paraboloid of revolution. In geometry, a paraboloid is a quadric surface that has exactly one axis of symmetry and no center of symmetry. The term "paraboloid" is derived from parabola, which refers to a conic section that has a similar property of symmetry. Every plane section of a paraboloid made by a plane parallel to
A contour chart of scale factors of GS50 projection Maps reflecting directions, such as a nautical chart or an aeronautical chart , are projected by conformal projections. Maps treating values whose gradients are important, such as a weather map with atmospheric pressure , are also projected by conformal projections.
Hyperbolic paraboloid A model of an elliptic hyperboloid of one sheet A monkey saddle. A saddle surface is a smooth surface containing one or more saddle points.. Classical examples of two-dimensional saddle surfaces in the Euclidean space are second order surfaces, the hyperbolic paraboloid = (which is often referred to as "the saddle surface" or "the standard saddle surface") and the ...
A transition map provides a way of comparing two charts of an atlas. To make this comparison, we consider the composition of one chart with the inverse of the other. This composition is not well-defined unless we restrict both charts to the intersection of their domains of definition. (For example, if we have a chart of Europe and a chart of ...
This template generates line and point charts in a structured and readable svg format. The original values are provided unmodified for the SVG file. Therefore the data of the chart may be checked and added at any time directly in the native file with any text editor. Instructions for a simple line plot:
