sdts++ is a free C++ toolkit that can be used to write applications that read and write Spatial Data Transfer Standard (SDTS) files. Currently there is a great deal of free geospatial data stored in SDTS format, including USGS Digital Line Graph (DLG) and USGS Digital Elevation Model (DEM) data.

Release Notes: Visual C++ 6.0 support, and minor bugfixes.


Release Notes: Added ability to write optional ISO 8211 record identifier field. This is important in that certain legacy GIS clients use the old FIPS 123 (ISO 8211) C library, which treats that as a mandatory field, and not as a proper optional field. Please note that this behavior is toggled on by default for sio_Writer objects. Also cleaned up generated HTML file, insured that that and other documentation files are now included in the distribution and some minor bug fixes.


Release Notes: Fixed bug whereby the final unit terminator in the DDR's file title reserved field wasn't getting written out. This means that any SDTS modules written by earlier versions of sdts++ might not be compliant with the ANSI SDTS specification.


Release Notes: Fixed problem where in reading a module the first subfield in repeating fields would get skipped.


Release Notes: This is the initial publically announced release of sdts++.
