     1= Grid Mapping: Adding new grid mappings =
     2
     3== Title ==
     4
     5Add new grid mappings to the existing list.
     6
     7== Requirement ==
     8
     9A number of grid mappings are being used that are not listed in CF. Make additions to the existing list.
     10
     11This is a follow-up proposal to the proposal in CF Trac ticket #18.
     12
     13== Summary of Change ==
     14
     15Add new grid mappings and required attributes.
     16
     17== Benefit ==
     18
     19Allow existing data using non-CF defined grid mappings to be CF compliant.
     20
     21== Status Quo ==
     22
     23Data that can not be CF compliant due to the grid mapping used.
     24
     25== Initial Statement of Technical Proposal ==

     75|| '''Attribute''' || '''Description''' ||
     76|| perspective_point_height || When applicable, records the height, in meters, of the map projection perspective above the ellipsoid (or sphere). Used by perspective-type map projections, for example the Vertical Perspective Projection, which may be used to simulate the view from a Meteosat satellite. ||
