Projection azimutale : dite aussi projection zénithale. La surface de projection est un plan rectangle tangent à la sphère sur lequel on projette une partie du globe. Ce point tangent (contact entre l’ellipsoïde et la surface de projection) est appelé centre de projection. 2, record 1, French, - projection%20azimutale

La projection azimutale équidistante de Guillaume Postel (1510 - 1581) n'est ni équivalente ni conforme. [...] En vue polaire, les méridiens et les parallèles sont divisés de manière à préserver l'équidistance. Toutes les formes sont faussées, sauf au centre, et la déformation s'accroît au fur et à mesure que l'on s'éloigne du centre. Les projections en vue polaire sont les mieux adaptées pour les régions de grandes latitudes car on peut aller jusqu'au 51e parallèle avec une déformation de seulement 15 %. C'est ainsi que la carte se trouvant sur le drapeau de l'ONU représente le monde en projection azimutale équidistante centrée sur le Pôle Nord. 4, record 2, French, - projection%20azimutale%20%C3%A9quidistante

An azimuthal map projection having the pole of the projection at the center of the area mapped. The azimuths of great circles radiating from this center (pole) are truly represented on the map: equal distances on those great circles are represented by equal linear distances on the map, but the scale along those great circle lines so varies with distance from the pole of the projection, that an equal-area projection is produced. 1, record 3, English, - Lambert%20zenithal%20equal%2Darea%20map%20projection

Projection azimutale dont le pôle se trouve au centre de la surface cartographiée. Les azimuts des grands cercles rayonnant à partir de ce centre sont véritablement représentés par des distances linéaires, équivalents sur la carte, mais la variation de l'échelle le long de ces grands cercles en fonction de la distance à partir du pôle de la projection est telle que l'on obtient une projection équivalente. 3, record 3, French, - projection%20%C3%A9quivalente%20de%20Lambert
