Northern Ireland's First Space Data Hackathon
Space Data Hackathon
Over the weekend past (23-25 Feb), Code4Good NI in collaboration with Kainos hosted a hackathon at the new computer science building at Queen's University Belfast. The hackathon was themed on Earth Observation data, inspired by one of the key themes of the Northern Ireland Science Festival: Space. Why is Kainos interested in space anyway? Well it seems pretty obvious when you consider how much they have invested in artificial intelligence and AI Camp. These days, there are a lot of notable Earth Observation data providers out there such as Airbus and Copernicus.
*Jk, of course I know Stormont!
What is Earth Observation data?
EO data is gathered by satellites orbiting Earth. The satellites use optical imagery as well as radar sensors to get extremely high resolution 3D imagery of the planet. Airbus kindly provided some optical and radar images of Belfast, Enniskillen, and Derry for the hackathon. However, EO data is notorious for being difficult to work with. Some of the challenges that exist are:
- the tools required to process the data are hard to use
- the development environment is difficult to set up
- the sheer size of data**
- Solve a problem for Smart Cities Belfast
- Build a useful dataset
- Improve council asset management
- Make city living better for residents
- Knowing all the bonfire locations
- Measuring proximity to residential areas
- Detecting illegal materials, such as tyres
- Detecting a bonfire that's getting too large earlier
- Space data is indeed hard. The images we were given were so huge that sometimes they'd crash our computers and the only tool we could use to display them was QGIS - which is very intimidating if you've never used it before! Thankfully, the teams had Jordan McDonald for support with using the tools.
- Preparation of space data is difficult and it's important to have a large enough and clearly defined dataset for machine learning to really work. There was a lot of trial and error in our team while trying to create a dataset of bonfire and nonfire images - probably about 95% of our effort was spent on this!
- The Belfast Tech Community have a great collaborative spirit! Despite competing, everyone helped each other out troubleshooting problems with tools or data. It was great to be a part of it!
Thanks to my team for a fantastic weekend and all the hard work:
