Geodesic Grid - Positive Traits

Positive Traits

  • Largely isotropic.
  • Resolution can be easily increased by binary division.
  • Does not suffer from over sampling near the poles like more traditional rectangular longitude/latitude square grids.
  • Does not result in dense linear systems like spectral methods do (see also Gaussian grid).
  • No single points of contact between neighboring grid cells. Square grids and isometric grids suffer from the ambiguous problem of how to handle neighbors that only touch at a single point.
  • Cells can be both minimally distorted and near-equal-area. In contrast, square grids are not equal area, while equal-area rectangular grids vary in shape from equator to poles.

Famous quotes containing the words positive and/or traits:

    Blessed be the inventor of photography! I set him above even the inventor of chloroform! It has given more positive pleasure to poor suffering humanity than anything else that has “cast up” in my time or is like to—this art by which even the “poor” can possess themselves of tolerable likenesses of their absent dear ones. And mustn’t it be acting favourably on the morality of the country?
    Jane Welsh Carlyle (1801–1866)

    As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.
    Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 1 (1991)
