Map projections supported by projfwd and projinv
projlist(listmode)
S = projlist(listmode)
projlist(listmode) displays a table of projection
names, IDs, and availability. listmode can be
'mapprojection', 'geotiff',
'geotiff2mstruct', or 'all'. The default value
is 'mapprojection'.
S = projlist(listmode) returns a structure array
containing projection names, IDs, and availability. The output of
projlist for each listmode is described
below:
mapprojection — Lists the
map projection IDs that are available for use with projfwd and projinv.
The output structure contains the fields
Name — Projection name
MapProjection — Projection
ID
geotiff — Lists the GeoTIFF
projection IDs that are available for use with projfwd and projinv.
The output structure contains the fields
GeoTIFF — GeoTIFF projection
ID .
Available— Logical array
with values 1 or 0
geotiff2mstruct — Lists
the GeoTIFF projection IDs that are available for use with geotiff2mstruct.
The output structure contains the fields
GeoTIFF — GeoTIFF projection
ID
MapProjection — Projection
ID
all — Lists the map and
GeoTIFF projection IDs that are available for use with projfwd and projinv.
The output structure contains the fields
GeoTIFF — GeoTIFF projection
ID
MapProjection — Projection
ID
info — Logical array with
values 1 or 0
mstruct — Logical array
with values 1 or 0

MapProjectionprojfwd and projinv can
be used to process certain forward or inverse map projections. These
functions are implemented in C using the PROJ.4 library. projlist provides
a convenient list of the projections that can be used with projfwd or projinv.
Because projfwd and projinv accept
either a map projection structure (mstruct) or a GeoTIFF info structure, projlist provides
separate lists for each case. It can also list the projections for
which a GeoTIFF info structure can be converted to an mstruct.
