How to convert Geocaching GPX file to WPT for OziExplorer

The goal is simple: convert GPX file from Geocaching.com to WPT file for Ozi Explorer and keep correct encoding of Slovak, Czech and German special characters.
Install GPSBabel and iconv. Store following script to file convert-gpx2wpt:


if [ -z "$2" ]; then
    echo "Specify input and output file"
    exit 1


iconv -c -f utf8 -t cp1250 < "$INPUT_FILE" > "$TEMP_FILE"
gpsbabel -i gpx -f "$INPUT_FILE" -o ozi,pack -F "$OUTPUT_FILE"

How to use:

chmod a+x convert-gpx2wpt
./convert-gpx2wpt input-file.gpx output-file.wpt

You can watch full movie Home (2009) at YouTube.

The author is Yann-Arthus Bertrand,

There is one very critical problem mentioned in the movie. It’s the methane in Siberia and other places.

Releasing methane from permafrost regions is also known as Permafrost Methane Time Bomb.

Quote from Wikipedia: The frozen peat bogs in this region may hold billions of tons of methane gas, which may be released into the atmosphere. Methane is a greenhouse gas 22 times more powerful than carbon dioxide.

You can find KML files for Google Earth with permafrost map info and other data at web site of National Snow and Ice Data Center.
