-/* tpo_write_file_header()
- Write the appropriate header for the desired TOPO! state.
-
- National Geographic sells about 75 different state and regional software
- programs called TOPO! that use the TPO format. Each one uses a different
- header data sequence. The header contains the name of the state maps, as well
- as some map scaling information and other data. In most cases, you can't open
- a TPO file created by a different state/regional version of TOPO! than the one
- you're using yourself. When writing a TPO file, it is therefore necessary to
- specify what TOPO! state product to create the file for. I believe that the
- TOPO! regional products can open TPO files created by the TOPO! state products
- as long as the track data is within the area covered by the regional product.
- As a result, it's only necessary to decide what state product output format to
- use.
-
- TO ADD SUPPORT FOR ANOTHER STATE:
- 1. Obtain an example .tpo file generated by the state product for which you wish
- to add support. National Geographic MapXchange (http://maps.nationalgeographic.com/topo/search.cfm)
- is a good source of .tpo files.
- 2. Run gpsbabel using the "dumpheader" option of the TPO format converter, and
- specifying a dummy output file. For example:
- gpsbabel -t -i tpo,dumpheader=1 -f sample_file.tpo -o csv -F dummy.txt
- This will write a snippet of C code containing the header bytes to the shell window.
- 3. Add a new if() clause to tpo_write_file_header(). Copy the header bytes definition
- from the previous step.
- 4. Recompile gpsbabel.
- 5. You should now be able write TPO output in the new state's format. For example, if
- you added support for Texas:
- gpsbabel -t -i gpx -f input.gpx -o tpo,state="TX" -F output.tpo */
