Meetkoppel - Opening and welcome

Welcome-address, introducing ourselves and sorting out technical hiccups.

hackathon: Meet je Stad - Data disclaimer

A wide variety of measurments are being gathered. Some high precision and well validated, others unfiltered raw measurements by undocumented sensors. Could a standard data disclaimer help to assess what kind of data live in a certain repository?

brainstorm: Meet je Stad - combine data layers on a map

Meet je Stad has heat data, the municipality data about green versus stones, other sources have even more data. Can we combine that data as layers on a map? In this session we will make an inventory of the data that we have and that might be valuable to combine. We will also think of how to do it and provide an working first version.

hackathon: Diana Wildschut/Dimitri van Dam - Meet je stad Phone App

Goal: a functioning Android app that displays data from Meet je Stad
For years now, Meet je Stad has wanted an open source smartphone app to make it easier to see the data of your sensor, add a flora observation, see where the coolest bike routes are and genarally stay more involved. Attempts have been made but have so far stranded. During datakoppel we will finally make it. Come and help code, design or think about this app! Bring your laptop, bring your smartphone.
Possible functions:
enter an id and see the current data for that node, like https://meetjestad.net/node/111
show a map to navigate, and make nearby nodes clickable
show a heat map for the erea you are in
enter a flora observation
show a map to navigate, and make nearby data clickable

lecture: Ton Zijlstra - The Emerging EU Legal Framework on Data and AI

The EU is creating a geopolitical perspective on data and AI, different from the surveillance capitalism in the US and the data driven authoritarianism in China.
In the past year and this year the EC has proposed a wide range of new legal instruments, which will go into force in the coming years. It concerns data sharing, sectoral data spaces, AI, around topics such as climate adaptation, health, energy transition and much more. All tied to how it impacts human and citizen rights. I will describe the legal framework as it is now being built, so we can discuss where it creates opportunities and safeguards for e.g. citizen science projects.

brainstorm: Philip ter Laak (municipality of Amersfoort) - How to use data to combat urban heat

Climate change causes temperature to rise. Amersfoort Municipality wants to combat urban heat stress, create a more pleasant environment during hot summer days and limit health risks. Cooling is the first thing we think about. Cooling houses, but also creating cool places in the city where people can “flee” to during the hottest moment of day.
But… we don't really know where to get started. We believe that data, especially from ‘Meet je stad’, can help us with this. This can help us with prioritizing in locations and tell us the effect of different measures. Can we effectively combat heat stress by creating cool places? Are we spending our money efficiently?
We would like to work with ‘Meet Je Stad’ to turn data into useful information, with which we change things outside to make the urban environment healthier and more pleasant.
Let's get started with that during Koppelting.


Questions that we have concerning this include: what is that we want to measure, and what can we actuallo do (differently) with this data? Can we go from data to insights, and from insights to actions? What is needed to do so?

hackathon: Meet je Stad - Datascratch

Data analysis and visualisation often requires quite some digital skills. The learning curve for most data software is rather steep.
Why not build a data tool that works for non programmers, inspired by Scratch, Pure Data, MaxMSP and the like.

hackathon: Paul Brouwer en Anne Vrouwe - Data quality and calibration of (DIY) soil moisture sensors

Past year we worked on developing a DIY sensor for measuring soil moisture on multiple depths.The data gathered from the first pilot sensors shows that data quality and calibration of the soil moisture sensors is a challenge. In this session we would like to
- explain more about this challenge,
- work together to find out how we can improve the data quality and calibration
- present our findings and ideas for next steps at the end of the day.

brainstorm: Freyja Schmitz - De impact van citizen science op overheidsbeleid

Voor mijn masterscriptie doe ik onderzoek naar de ervaren impact van citizen science op overheidsbeleid. In deze sessie wil ik de discussie aangaan over impact maken op overheidsbeleid met citizen science. Hoe kan deze impact ervaren worden en wat is er nodig om citizen science terug te vinden in overheidsbeleid?

lecture: Teus Hagen, ver. Behoud de Parel - (dust) sensors differ: so what!

Low cost dust sensors count particles. Only a few manufacturers show also the count values.
Can we improve the quality of these mass dust measurements?
From may 2021 we correct the mass values using measurements with several dust sensors at a governmental air quality measurement station in Vredepeel.

lecture: Miriam van den Beemt - Monitor of the City - from data to activation

In Tilburg we combine different datasets to adress challenges related to the sustainable development goals: for example Meet je Stad temperature data, KNMI temperature data en open data from the municipality regarding green/stone ratio in the city. The visualisation is presented on a big screen in our main library, the LocHal. But presenting is not enough; we organize activities on different levels to engage the inhabitants with the subject at hand. To accomplish this we work together with a lot of local partners. We call this total approach Monitor of the City.

brainstorm: SMAL Zeist / Egon Kastelijn - Moving from Raw Data to Real Value, and from Nice-to-have to Needed

SMAL Zeist is a citizen science initiative that has been measuring air-quality for 3 years, and has created a rich dataset with 50GB of measurements and metadata.
This is nice, but we have to be honest: The data has a limited value in its raw form.
We believe that the data has much more potential.
It's value would increase greatly if we would combine it with other sources and create applications that would be used in everyday life or even (indirectly) for policy-making.

SMAL Zeist is exploring the possibilities to move from 'technical data' to 'real value', and from 'nice to have' to 'needed'.

For example:
* Can we think of applications where the data would be needed in everyday life?
* Are we missing certain data (sources) to create those applications?
* What would be needed to use the data in an educational environment?
* How can the data be published in a more accessible and attractive way besides just webportals, to create more awareness?
* Do we believe that a citizen science community can create and maintain applications that have more importance/relevance and require a higher availability?

We believe that if we can create a tighter connection between the data/platform and some real-life use-cases, that the value of the total platform would increase greatly.
This would help the citizen science initiative to grow to the next maturity level.
