maps

List projection names or projection codes

Syntax

• maps 
  strmat = maps('namelist')
  strmat = maps('idlist')
  stdstr = maps(id_string) 
  

Description

maps displays in the command window a table describing all projections available for use.

strmat = maps('namelist') returns the English names for the available projections as a matrix of strings.

strmat = maps('idlist') returns the standard projection identification strings for the available projections as a matrix of strings.

stdstr = maps(id_string) returns the specific standard projection identification string associated with a unique truncation abbreviation.

Examples

To show the first five entries of the projections name list:

• str1 = maps('namelist');
  str1(1:5,:)
  ans =
  Balthasart Cylindrical          
  Behrmann Cylindrical            
  Bolshoi Sovietskii Atlas Mira   
  Braun Perspective Cylindrical   
  Cassini Cylindrical    
  

The corresponding shorthand names are:

• str2 = maps('idlist');
  str2(1:5,:)
  ans =
  balthsrt   
  behrmann   
  bsam       
  braun      
  cassini    
  

These are the strings used, for example, when setting the axesm property MapProjection.

The functions setm and axesm recognizes unique abbreviations (truncations) of these strings. The maps function can be used to convert such an abbreviation to the standard id string:

• stdstr = maps('merc')
  stdstr =
  mercator
  

When the function name alone is used:

The actual result contains all defined projections.
