MagicBox Aggregate Mobility

Aggregate Amadeus mobility data by administrative boundary to produce CSV output

What is this?

This repository aggregates Amadeus mobility data by administrative boundaries to output a CSV file where each line is orig,dest,count.

Administrative boundaries (ABs) are concepts to describe different geospatial concepts, like countries, states, provinces, and more. Read more about ABs on the MagicBox wiki.

Why we use it

Amadeus provides a lot of raw data. Not all of it is useful for MagicBox. This tool reduces the amount of data into three fields:

• orig: Origin airport
• dest: Destination airport
• count: Number of people traveling between orig to dest

This data helps us understand travel patterns for MagicBox. For example, we may be able to predict a risk of a virus (e.g. Zika) to spread to a new location.

Getting started

These instructions get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• Node.js 7.0 or later
• gzip
• Apache Spark
  • Java JDK 7 or later
  • Apache Hadoop

Make sure JAVA_HOME environment variable is set on your system. If you install Hadoop and Spark from the source, make sure they are on your system PATH (e.g. hadoop-3.0.0/bin and spark-2.2.1-bin-hadoop2.7/bin).

Installing

Run these commands at a command prompt.

clone https://github.com/unicef/magicbox-aggregate-mobility.git
agicbox-aggregate-mobility
onfig_sample.js config.js
install

Usage

Configuration

There are a few different options to set in the config.js file:

• zipped: Stores compressed Amadeus traffic data
• processed: Final location of processed data
• spark_path: Install location of spark shell binary spark-shell. Leave blank if spark-shell is in your path. note: please include a trailing slash.
• aggregation_level: value in form adminX where X is one of 0, 1, 2, 3, 4 or 5. The administrative level boundary level data should be aggregated to.
  
• fields: Filtered fields from raw Amadeus data

To get the compressed data?

More info coming soon.
