The flag of the United Nations is a sky blue banner containing the United Nations ' emblem in the centre. The emblem on the flag is coloured white; it is a depiction of the world map in the azimuthal equidistant projection (centred on the North Pole ), which is surrounded by a pair of olive branches. The emblem was officially adopted on 7 ...
A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections. Depending on configuration, the projection also may map the sphere to a single diamond or a pair of squares. Hybrid of Collignon + Lambert cylindrical equal-area.
In three dimensions, the locus of points equidistant from two given points is a plane, and generalising further, in n-dimensional space the locus of points equidistant from two points in n-space is an (n−1)-space. For a triangle the circumcentre is a point equidistant from each of the three vertices. Every non-degenerate triangle has such a ...
The equirectangular projection (also called the equidistant cylindrical projection or la carte parallélogrammatique projection ), and which includes the special case of the plate carrée projection (also called the geographic projection, lat/lon projection, or plane chart ), is a simple map projection attributed to Marinus of Tyre, who Ptolemy ...
Louis de Batz de Castelmore (the younger), born 4 July 1661 in Chalon-sur-Saône, was a knight, later known as count d’Artagnan, baron of Sainte-Croix, lord of Chanlecy and Castelmore, and became maréchal de camp. He married on 21 May, 1707 Marie Anne Amé (1670–1714) and died on 7 June, 1714 at the castle of Sainte-Croix. [ 5]
Calypso Deep, Ionian Sea, Greece (5,267 metres; 17,280 feet below sea level). Lowest point (natural, underground). Dependent upon the definition of Europe: either Krubera Cave, Abkhazia, Georgia (2196 metres; 7205 feet below surface) (also the deepest cave in the world) [ 2] or Lamprechtsofen, Austria (1,632 metres; 5,354 feet below surface).
The two-point equidistant projection or doubly equidistant projection is a map projection first described by Hans Maurer in 1919 and Charles Close in 1921. [1] [2] It is a generalization of the much simpler azimuthal equidistant projection. In this two-point form, two locus points are chosen by the mapmaker to configure the projection.
The azimuthal equidistant projection is an azimuthal map projection. It has the useful properties that all points on the map are at proportionally correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar ...
