This is the code of an app submited to the GreatUniHack hackaton 2015. It received the prize for the best use of the CDL API.
After the recent climate change conference we wondered if we could get a rough estimation of car co2 emissions in the UK based on the real mileage of vehicles.
It visualises an estimated of car co2 emissions per manufacturer and per year.
The backend runs in NodeJS and queries the ElasticSearch instance of CDL to retrieve MOT test data. Using the mileage of each tested car and data publicly available from the UK government about the registered average emissions of each manufacturer we came up with an estimation of CO2 emissions per post code area in the UK. You can also visualise the emission per year from 2008 for all the manufacturers.
Mashup CO2 emissions data with CDL data. Handling of big amounts of data coming from the CDL ES instance. NodeJS (it was the first time we used it)
The mashup of data and the map visualisation of the emissions using JavaScript
NodeJS, and bits of python scripting.
Maybe visualise other variables.
