sdtsinfo

Information about SDTS data set

Syntax

info = sdtsinfo(filename)


Description

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.

Field Descriptions

The info structure contains the following fields:

Filename	Name of the catalog directory file of the SDTS transfer set, specified as a character vector.
Title	Name of the data set, specified as a character vector.
ProfileID	Profile Identifier, e.g., 'SRPE: SDTS RASTER PROFILE and EXTENSIONS', specified as a character vector.
ProfileVersion	Profile Version Identifier, e.g., 'VER 1.1 1998 01', specified as a character vector.
MapDate	Date associated with the cartographic information contained in the data set, specified as a character vector.
DataCreationDate	Creation date of the data set, specified as a character vector.
HorizontalDatum	Horizontal datum to which the data is referenced, specified as a character vector.

YResolution	Scalar value representing the Y component of the horizontal coordinate resolution
NumberOfRows	Scalar value representing the number of rows of the DEM
NumberOfCols	Scalar value representing the number of columns of the DEM
HorizontalUnits	Units used for the horizontal coordinate values, specified as a character vector.
