    2121== Status Quo ==
    2222
    23 Data that can not be CF compliant due to the grid mapping used.
     23CF compliant data using grid mappings that are not supported by CF.
    2424
    2525== Initial Statement of Technical Proposal ==
     
    2727=== Add Examples to Appendix F ===
    2828
    29 ==== Example F.9. Vertical Perspective ====

    31 {{{
    32 grid_mapping_name = vertical_perspective
    33 }}}
    34 
    35 ===== Map parameters: =====
    36 
    37  * ''longitude_of_projection_origin''
    38  * ''latitude_of_projection_origin''
    39  * ''perspective_point_height''
    40  * ''false_easting''
    41  * ''false_northing''
    42 
    43 ===== Map coordinates: =====
    44 
    45 The x (abscissa) and y (ordinate) rectangular coordinates are identified by the ''standard_name'' attribute value ''projection_x_coordinate'' and ''projection_y_coordinate'' respectively.
    46 
    47 ===== Notes: =====
    48 
    49 Notes on using the PROJ.4 software packages for computing the mapping may be found at http://www.remotesensing.org/geotiff/proj_list/geos.html. These notes assume the point of perspective is directly over the equator. A more general description of vertical perspective projection is given in [Snyder], pages 169-181.

    72 === Add the following attributes to Table F.1 ===
    73 
    74 || '''Attribute''' || '''Description''' ||
    75 || 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. ||
