JaVaWa RTWtool

JaVaWa RTWtool (the successor of MacGPX) is a program that allows various conversions of routes, tracks and waypoints. There are options to 'unflag' routes, convert routes to tracks and vice versa, convert a collection of waypoints to a track or direct route.

Routes and tracks can be filtered to limit the number of points per route/track, and they can be split if they exceed a specified length. Tracks can be joined together.

Tracks and waypoints can be enriched with elevation data, and tracklogs can be cleaned up.

Route points accidentally put off road can be corrected automatically.

Routes and tracks can be converted to a series of waypoints in a POI file; optionally in a form like the Hermanizer.

Furthermore, routes and tracks can be converted to courses for the Garmin Edge, with the ability to automatically generate course points which warn you for changes in directions in a track or for turns in a route. Waypoints can also be converted to course points.

Finally, there are conversion options for TomTom, Google Earth, a Web map and extensive options for text files (CSV/TXT).

Routes, tracks and waypoints can be separately converted and/or processed, and both the input and the result can be displayed on a map.

File formats

JaVaWa RTWtool not only supports GPX files, but a variety of different file formats.
The following file formats can be read:

1) uses two different GPX formats; one of them isn’t compatible with Garmin devices. JaVaWa RTWtool supports both and saves them always in the Garmin-compatible format.
2)The GDB format has certainly some advantages (compact, suitable for large amounts of data, fast processing in JaVaWa GMTK), but it's somewhat outdated: it doesn't support non-announced via points, or things like cadence or heartbeat. In most cases it is better to use the GPX format.
3)When having a corrupt FIT file, most of the times JaVaWa RTWtool can read it. It will be indicated when a file is not complete.
4)Some KML or KMZ files don't contain (or just a few) placemarks and/or paths, while Google Earth shows them all. In that case the file contains "Network Links". Network links are references to other KML/KMZ files (usually) on the internet. JaVaWa RTWtool downloads and processes these Network Links automatically.
Network Links pointing to locally stored files won't be processed; open the original files instead.
5)Because CSV (and similar) files aren't standardised upon import you will get a dialog where you can select the list separator and the field order. More info in the manual.
6)Shapefiles often use another coordinate system than WGS84. JaVaWa RTWtool supports several transformations: Dutch Grid, Lambert 2008, Lambert 72 (both used in Belgium) and Universal Transverse Mercator (UTM) to WGS84. Upon import of a shapefile you will get a dialog where you can select the transformation, the text encoding (usually Windows-1252) and which shape fields need to be connect to which GPX fields.
7)JaVaWa RTWtool supports only ASCII DXF; no binary DXF. The remark above about transformations also applies to DXF files.

JaVaWa RTWtool can write to the following file types:

8)A FIT file always contains a single course. When converting several courses simultaneously, the first file will get name that you have specified, the others will have a sequential letter appended to the name.

When importing and converting additional attributes like cadence, heart rate and temperature will be processed too.

Text files

There is no standard for waypoints in a text file with list separators; therefore the layout can be very different. Also differences in coordinate format, list separator and text encoding will occur.
JaVaWa RTWtool can handle (almost) every combination; it requires more user interaction than other file formats though.
Upon import JaVaWa RTWtool will show a dialog box where you can set the following parameters: list separator, text qualifier, text encoding (90 different ones) and coordinate system (WGS84, Dutch Grid, Lambert 2008, Lambert 72, Universal Transverse Mercator coordinate system (UTM), Military Grid Reference System (MGRS) and Maidenhead Locator System).
You can assign columns to a large choice of waypoint items.

There are similar options for exporting to a text file.
