RallyGPXMerger

A web tool to merge GPX tracks for big bike rallies written in React and TypeScript, with a simple backend storing JSON files.

Current deployment

The current version of this tool is deployed here: https://www.sternfahrtplaner.de/

You can find an example of a more complicated planning here: https://www.sternfahrtplaner.de/?section=gps&planning=ce4e62a5-3b73-4fa1-80e3-d66d687c2439 Sketch

Why does this tool exist

When planning a bigger bike demonstration or rally it is a lot of work to not only decide about the routes. You also have to

consider the timing, breaks, confluences of tracks
communicate your tracks with officials
communicate your tracks with participants
apply changes and do all of it again

To ease these processes, this tool was developed to have an easy interface to the planning and reduce the manual work or copying information. This tool does not provide any route planning because this is a common problem which is not unique to organizing rallies. During the development it showed, that also for smaller bike demonstration it can help. Therefore, now there are two modes of planning: one for a simple "line" demonstration and another one for more complex "tree" ones

General functionality

Automatic time calculation for the tracks
- Setting the speed in general and for segments
- Taking the number of participants into account
Preview of the resulting demonstration with a time slider
Combining segments and breaks to a track
Replace segments in tracks when changes are required
Cut segments via a left click into pieces (e.g. to add a break in a track)
Choose what to display on the map in the planner
- Filter for segments or tracks
- Toggle segments, tracks and others
Live view with integration of the criticalMaps API
- When participant use the CriticalMaps App, their location is displayed on the map
Automatic resolving of street names and post codes
Creation of PDF files containing a detailed overview of the streets and times
Allow to publish the plan as a map
Allow to publish the plan as a table (e.g. to integrate on your website)

Simple ("Line")

The workflow for a simple demonstration

Upload gpx segments into the browser
Reorder them via drag and drop
Integrate breaks into the track
Name the planning and choose settings
Upload the planning
Share or publish the planning in form of PDF, or links, or iframes, as map or as table

Complex ("Tree")

The workflow for a complex demonstration

Upload gpx segments into the browser
Create tracks
Add segments to the tracks (segments can be used multiple times, when the different branches join)
Integrate breaks into the track
Name the planning and choose settings (e.g. rounding of start times)
Calculate the planning
Upload the planning
Share or publish the planning in form of PDF, or links, or iframes, as map or as table
