The equations involved are relatively straight-forward, +and for certain instructional tools and databases, the projections are useful +for world maps. The interruptions remain a disadvantage, as with any low-error +projection system applied to the entire globe :cite:`Snyder1992`. + + ++---------------------+----------------------------------------------------------+ +| **Classification** | Polyhedral, equal area | ++---------------------+----------------------------------------------------------+ +| **Available forms** | Forward, spherical | ++---------------------+----------------------------------------------------------+ +| **Defined area** | Global | ++---------------------+----------------------------------------------------------+ +| **Alias** | isea | ++---------------------+----------------------------------------------------------+ +| **Domain** | 2D | ++---------------------+----------------------------------------------------------+ +| **Input type** | Geodetic coordinates | ++---------------------+----------------------------------------------------------+ +| **Output type** | Projected coordinates | ++---------------------+----------------------------------------------------------+ + + .. figure:: ./images/isea.png :width: 500 px :align: center |
