Timetraveller

Webservice to explore spatio-temporal data in an interactive way.

Installation

git clone https://github.com/fnogatz/timetraveller.git
cd timetraveller
npm install

Maps

The available maps are configured by YAML files in the /maps directory. Simply copy the provided example.yml and change it to fit your needs.

Creation

Create a new YAML file in the /maps directory. The filename will be map's identifier. That means if you save a my-map.yml, this map will be accessable as http://domain.tld/my-map.

A step-by-step guidance to import and display GTFS transit data can be found in the wiki.

Server

You can start the webserver by calling:

npm start

Model Connectors

This is a list of currently available connectors.

• timetraveller-mongodb: Connector for MongoDB

Write your own

The timetraveller server can use any data source. A Connector object is used to access your data. It only has to provide the following signature:

// Constructor
var connector = new Connector(options)

// Method to find trajectories
connector.findTrajectories(query)
/**
 * Search parameters:
 *
 * query.time.start     (Start of time range)
 * query.time.end       (End of time range)
 * query.bounds.east    (Bounding Box)
 * query.bounds.west
 * query.bounds.north
 * query.bounds.south
 */
