maps

List available map projections and verify names

Syntax

strmat = maps('namelist')
strmat = maps('idlist')
stdstr = maps('proj_id_abbrev')

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 character vectors.

strmat = maps('idlist') returns the standard projection identifiers for the available projections as a matrix of character vectors.

stdstr = maps('proj_id_abbrev') returns the specific standard projection identification associated with a unique 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 shorthand names can be used, for example, when setting the axesm property MapProjection.

The functions setm and axesm recognize unique abbreviations (truncations) of these names. The maps function can be used to convert such an abbreviation to the standard ID:

stdstr = maps('merc')
stdstr =
mercator

When the function name alone is used,

The actual result contains all defined projections.
