NTXShape: NTX to Shapefile Converter
This is only a summary; the full home page, including application
binaries, project history, and source code, may be found at ntxshape.sourceforge.net.
NTXShape converts files from the CARIS NTX format into the widely
supported ESRI shapefile format. NTX is one of the standard formats used
to distribute digital maps in Atlantic Canada, and is also the former
standard for electronic charts from the Canadian Hydrographic Service.
The shapefile format was popularized by ArcView GIS. It is now supported
by all ESRI software and by a large number of third-party GIS
applications and data providers.
For those who wish to work with the source code, a development site is up
and running at SourceForge.net. There are also discussion forums for
both end users and developers.
