GDF Specification Variant
The specification to use when writing the output GDF file.
CEN 3.0 means that the official CEN 3.0 specification is used. NAVTEQ or TeleAtlas indicates that the NAVTEQ or TeleAtlas variants of the GDF specification is used, respectively. Best Guess tells the reader to use an intelligent guess as to which specification to use, based on the header of the GDF file it is overwriting, if any.
GDF Charset
The character set to use when writing the output GDF file. This option parallels the value found in the header of the input file on read but must be manually selected when creating an output file.
ASCII means that the data rows in the output file are written as single byte system-encoded strings. UTF-8 and ISO 8859-1 are specific character encodings for the output string data.
GDF End of Line
The type of end of line terminator to use when writing the output GDF file.
System (default) attempts to detect the platform in use and uses the appropriate end of line characters from among the other options. If GDF Charset is ASCII, a value of Windows uses a pair of <CR><LF> control characters, a value of Unix uses a single <CR> control character, and a value of Macintosh uses a single <LF> control character on older systems previous to the adoption of Unix-style end of line characters.
Note: The value of GDF Charset can affect the end of line characters and additional charset values may result in other end of line control characters.
