This approach is referred to as gnomonic time division.
For Panopea globosa the gnomonic approach was used as an alternative method for estimating natural mortality and it offers an alternative to traditional methods used for Panopea species that are focused on adult population parameters (e.
Estimates of natural mortality for Panopea globosa were computed using gnomonic time divisions (GTD) according to the definition provided by Caddy (1996).
Emerson's notes following an 1843 visit to a railroad construction site along the Boston Concord line show us that he sees the railroad as a gnomonic project consisting of iterative growth:
Continuity along the edges is also obtained for the Gnomonic projection (Maling 1993), where these same circumcenters serve as the points of tangency.
Johnson's Shrubberies, on the other hand, share Dickinson's gnomonic geometry and use language like a sundial, an encultured way of measuring nature's time and space in a poet's line:
In all cases they transformed the resulting cells to the sphere, using direct spherical subdivision or the inverse gnomonic, Fuller/Gray, or Icosahedral Snyder Equal Area (ISEA) map projections.
1998 Direct Spherical Subdivision, Gnomonic, ISEA, or Fuller/Gray White 2000 Not Specified Wickman et al.
If cell compactness is of prime importance, for example, a triangular or hexagonal grid based on partitioning a Gnomonic map projection of an icosahedron face (not discussed in this article) would be the best alternative, closely followed by direct spherical subdivision, the small circle subdivision method, and the Fuller-Gray map projection for the icosahedron.
Indeed, the only edge-preserving transformations from sphere to plane are gnomonic projections followed by arbitrary perspective or affine transformations of the plane to itself; and none of these composite transformations preserve the Delaunay property (empty circumcircles).
