Yatayat

Kathmandu Public Transport

Openstreetmap-based point-to-point routing, developed for Kathmandu.

HACKING / DEPLOYING

submodules

yatayat uses a kdtree implementation from @ubilabs on github; to use it you will need to run

% git submodule init
% git submodule update

inside your cloned repository

config

config.js pulls from a overpass-api directly; to develop locally, you can symlink config.local.js to config.js, but please be careful not to commit your symlinked file

% ln -s config.local.js config.js

Data Model

OSM Data is transformed into Routes, Stops, and Segments:

Route:

• id
• name
• ref // route number
• transport // type of transport; pulled from tag.type
• stops: [] // are ordered
• stopDict: {} // indexed by id
• segments: []
• tag: {}

Stop:

• id
• name
• lat
• lng
• tag: {}

Segment:

• listOfLatLng: [(lat,lng), ...]
• tag: {}

CLI

data quality.

These make use of nodejs. On Debian-based systems, all external dependencies can be installed via APT:

% apt-get install nodejs node-jquery node-underscore

Elsewhere, you can try your luck with NPM:

% npm install jquery underscore docopt

Then, you can run:

% nodejs cli_dataquality.js transit.experimental.xml

Additionally, the "datasync.py" python wrapper downloads the latest route information from OSM through overpass, checks for quality issues, and depending on the results of cli_dataquality, can e-mail relevant parties or else commit the new info into git.
