GPX Tool Help

GPX, or GPS Exchange, files are used to import and export GPS user data between tools and devices. This tool reads a GPX file and converts it to a CSV, or Comma Separated Value, file which can be read by a spreadsheet program. In the future, this app will also allow you to clean up a GPX file.

Start at the top of the screen and work your way down. Unavailable options are greyed-out.

The GPX Tool performs two functions—creating a CSV from a GPX file and cleaning up a route in a GPX file.

Creating a CSV File

To create a CVS file from a GPX file, do the following:

• Click Show Help to see this information. Click Hide Help to continue.
• Click Show Options to set CSV options.
• Click Hide Options to save and continue.
• Click Choose File and select a GPX file.
• Click Upload GPX to upload the file for processing. The GPX file is displayed in a separate pane.

Cleaning a Route

There are up to three functions performed by clean route; Reordering waypoints, cleaning waypoint symbol names, and hiding waypoint names. There are two levels of cleaning— Clean All cleans all waypoints, but the default is to clean only automatic waypoints, and leave waypoints like anchorages alone.

After uploading a GPX file, the Clean Route button will be enabled if there is a route. Do the following to clean routes in the uploaded file:

• Click Show Options to set Clean options.
• Click Hide Options to save and continue.
• Change the value of Start Num to the starting number when reordering waypoints.
• Click Clean Route to clean the uploaded route. The cleaned GPX file is displayed in a separate pane.
• Click Download GPX to download the GPX file. The characters "_cln" are added to the file name to indicate that the route is cleaned. The route name is unchanged.
• Click Download CSV to download the cleaned CVS file.
• Click Clear to restart.

Clean Route Options

• Reorder – Reorder waypoint names, starting with Start Num.
• Num Digits – Number of digit to use for route name when reordering. The default is 3.
• Clean Sym – Clean waypoint symbols.
• Symbol – The symbol to use when cleaning symbols the default is Waypoint. (OpenCPN's default is diamond.)
• Hide Name – Hide waypoint name, for a cleaner looking route.
• Clean All – When checked, all waypoints will be cleaned according to above checked boxes. The default is to only clean automatic waypoints and leave waypoints like anchorages alone.

This tool should work on any device with a browser, but it is optimized for a PC.
