Contribute a City
Metroid is based on maps. A map encapsulates all data about a city : transportation lines, frequency, stops...
Metroid maps use the mtd file extension. These mtd files are compact and use up very little disk place. They are to be transfered and used on Android devices.
However, the mtd files must be generated with an utility specially created for that purpose. The data used to generate these files is based on a very simple text format. The following guide will show you the basics of that format. Metroid is a community driven project and needs your help to succeed. The more cities are covered, the better it is. So please don't hesitate to contribute and if you have any question or suggestion, feel free to contact us at webmaster@ycsoft.org.
If you want to help supporting a particular city, please prepare the data as explained below and send it to us by email at webmaster@ycsoft.org. We'll reply as quickly as possible with the generated mtd files. And if you agree, your city will be added to the central repository and thus be available to the whole community.

Most transportation system around the world are divided into Lines which in turn are a succession of stations(or stops). The Metroid data format follow that convention. The file starts with the .City specifying the city then the keyword .Mean telling which transportation mean is concerned. The mean could either be Metro(for Subway), Bus or Both (Metro + Bus).
These are general information about the map. They are then followed with as many Line data sections as necessary. Lines data begin with the keyword .Line followed by a : and the name of the line. The .TotalTime keyword specifies the number of minutes it takes to travel from the first stop in the line to the last one. It is used to compute the average travel between two adjacent stops. If not specified, it is assumed to be 5 min.
The .Frequency keyword indicates how often the bus (or the metro) passes.
Finally, the keyword .Stops must be added and followed with the list of all stops in the line.
