Description: The LeoNetCDF software application permits to display and edit content of binary NetCDF files in tree style control of a standard window interface environment. LeoNetCDF uses a state of art codes that are implemented a description of NetCDF format. It also can convert content of NetCDF file in and out a file in XML format that can be edited with any standard text editor application such as WordPad. Members of scientific and engineering communities are making a lot of measurement from different instruments and could want to be able to exchange them. The obvious problem that there could be various ways to present one set of data that create a virtual analogy of number of people's languages. Even more complicated as soon there is several operation systems that move us forward to the analogy with communications of different species that was even broad discussed only in sci-fi literature yet. One of the methods of solving this problem is an creation of universal format of data. If it exists the problem of conversion of data from one format to other could be tremendously simplified. The NetCDF format is an attempt to create such Universal DATA Format or (network Common Data Format).
