Information about SDTS data set
info = sdtsinfo(filename)
info = sdtsinfo(filename) returns
a structure whose fields contain information about the contents of
a SDTS data set.
filename is a string scalar or character vector that specifies the name of
the SDTS catalog directory file, such as
7783CATD.DDF. The file name
can also include the directory name. If
filename does not include the
directory, then it must be in the current directory or in a directory on the MATLAB® path. If
sdtsinfo cannot find the SDTS catalog file, it
returns an error.
If any of the other files in the data set as specified by the catalog file is missing, a warning message is returned. Subsequent calls to read data from the file might also fail.
info structure contains the following
Name of the catalog directory file of the SDTS transfer set, specified as a character vector.
Name of the data set, specified as a character vector.
Profile Identifier, e.g.,
Profile Version Identifier, e.g.,
Date associated with the cartographic information contained in the data set, specified as a character vector.
Creation date of the data set, specified as a character vector.
Horizontal datum to which the data is referenced, specified as a character vector.
Projection and reference system used, specified as one
of the following values:
Scalar value representing the zone number
Scalar value representing the X component of the horizontal coordinate resolution
Scalar value representing the Y component of the horizontal coordinate resolution
Scalar value representing the number of rows of the DEM
Scalar value representing the number of columns of the DEM
Units used for the horizontal coordinate values, specified as a character vector.
Units used for the vertical coordinate values, specified as a character vector.
Scalar value of the minimum elevation value for the data set
Scalar value of the maximum elevation value for the data set
