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 that specifies the name of the SDTS catalog directory file, such as 7783CATD.DDF. The filename 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.
The info structure contains the following fields:
Filename | String containing the name of the catalog directory file of the SDTS transfer set |
Title | String containing the name of the data set |
ProfileID | String containing the Profile Identifier, e.g., 'SRPE: SDTS RASTER PROFILE and EXTENSIONS' |
ProfileVersion | String containing the Profile Version Identifier, e.g., 'VER 1.1 1998 01' |
MapDate | String specifying the date associated with the cartographic information contained in the data set |
DataCreationDate | String specifying the creation date of the data set |
HorizontalDatum | String representing the horizontal datum to which the data is referenced |
MapRefSystem | String describing the projection and reference system used: 'GEO', 'SPCS', 'UTM', 'UPS', or '' |
ZoneNumber | Scalar value representing the zone number |
XResolution | Scalar value representing the X component of the horizontal coordinate resolution |
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 | String specifying the units used for the horizontal coordinate values |
VerticalUnits | String specifying the units used for the vertical coordinate values |
MinElevation | Scalar value of the minimum elevation value for the data set |
MaxElevation | Scalar value of the maximum elevation value for the data set |
