Available Mapping Toolbox map projections
list = maplist
[list,defproj] = maplist
list = maplist returns a
structure that lists all the available Mapping Toolbox™ map projections.
The list structure is
This list structure is used by the functions
processing map projection identifiers during operation of the toolbox
[list,defproj] = maplist also
returns the default projection's
list.Name defines the full name of the projection.
This entry is used in the command-line table display and in the Projection
list.IdString provides the name of the MATLAB® function
that computes the projection.
list.Classification defines the projection
classification that is used in the command-line table display.
list.ClassCode defines the character string
that is used to label the classes of projections in the Projection
Control Box. The eight class codes are
Azim — Azimuthal
Coni — Conic
Cyln — Cylindrical
Mazi — Modified azimuthal
Pazi — Pseudoazimuthal
Pcon — Pseudoconic
Pcy — Pseudocylindrical
Poly — Polyconic
When map projections are added to the toolbox, the list structure needs to be extended. For example, if a new projection is added to the default list, then a new entry in the list structure would be
list.Name(61) = 'My Projection' list.IdString(61) = 'newprojection'; list.Classification(61) = 'New Projection Type'; list.ClassCode(61) = 'Code';
