Figure 9 shows a spherical overset grid that consists of three identical component grids. In this case, the component grid is defined as a part (about 1/3) of the spherical surface by (π/4 ≤ θ ≤ 3π/4) ∩ (−π/2 ≤ ϕ ≤ π/2).

WebOct 15, 2011 · One simple method to construct such grids is to transfer existing planar grids. A complete description of all known spherical projections from a sphere or parts of a sphere to the plane, used in cartography, is realized in [1], [2]. However, most grid constructions given so far do not provide an equal area partition. WebA triangle on a sphere has the interesting property that the sum of the angles is greater than 180 degrees! And in fact, two triangles with the same angles are not just similar (as in planar geometry), they are actually congruent! But wait, there’s more: on a UNIT sphere, the AREA of the triangle actually satisfies: where the angles are ...
