Line-up for Meetkoppel'21

Is this the final lineup?

No, new contributions can be added up to or even during the event. Have something to contribute? Sign up and you can directly add something to this lineup.

When will these things take place?

The final schedule for the weekend will be published shortly before the event, since the lineup is still open for new contributions.

hackathon: Diana Wildschut - help build a Meet je Stad Andoid app

Ever since the start of Meet je Stad we have planned to build an Android app. So far, some attempts have been made, but no useful result. In this hackathon we will try again to build a very simple app and plan how to extend it in the future.

workshop: De WAR - Open Community License

Brainstorm about how to formulate an open community license.
For hardware as well as software there are open licenses that tell user what they can and cannot do when using the product.
Scientists, consultants and governments often write citizen science communities into their grant proposals without even consulting them, promising things that the community may not even approve of.
Communities have their own values and ways that make them what they are. Now that citizen science communities' merits, names and results are starting to get claimed by consultants, businesses and governments, maybe it is time to draft an open community license. This license should for instance tell under what conditions the name of a community project can be used.

lecture: Peter Demmer - Time graphs for measurement analysis

For the analysis of large amounts of diverse data, graphical presentation is essential.
Time and geographical graphs of various types are available on the Meetjestad website.
Focussing on the time graphs, an overview, explanation of their meaning and significance, and background about how they are made is provided.

lecture: Andries Lohmeijer - Using and Contributing to opensource, in our Company?

KITT Engineering is a small R&D Company specialized in Creative ICT projects. The team is used to high end commercial EDA tools. Last year we decide to participate in the open source project "MeetJeStad" using strictly open source tools and publish our results and contributions. How that work out? What were the problems we encountered, and what are the benefits?

demonstration: Paul Brouwer - Update on the new soil humidity sensor

The latest addition to Meet je Stad is a soil humidity sensor. It had to be cheap, diy and yet reliable.
In this demo we show the latest model, and discuss the pitfalls we encountered and the successes we had.

lecture: Paul Brouwer and Anne Vrouwe - Soil Moisture

Recently, together with the municipality we started measuring soil moisture on different locations within Amersfoort. Soil moisture is of key importance in the growth and well-being of plants and trees. However, many cities don't measure or monitor soil moisture levels. By measuring soil moisture in the city, we intend to get more insight into how it functions and how it is related to other indicators (such as precipitation and heat).

During this talk, Paul will talk about the topic from a Meet Je Stad perspective. Anne works at the municipality of Amersfoort and will explain how the municipality is involved.

hackathon: Harmen Zijp - Data Scratch

Many people have data, either from their home made sensor, from a weather station or from whatever other fascination.
But for non-programmers making a nice, insightful visualisation is a bit harder.
Wouldn't it be nice to have an open source, easy to use yet flexible toolkit for data visualisation?
We imagine a lego-like, Scratch-like system that allows you to connect building blocks that access data, process it and visualise it.
This is a brainstorm session in which we design an outline for how we wat it to work, and who knows, we might even start coding.

lecture: Harmen Zijp - How to start a citizen science community

Citizen science holds the twin promise to both collect local environmental data and engage a group of citizens around current societal topics. To successfully launch a sustainable effort however a bottom-up approach is needed that conflicts with received wisdom about prevalent top down models of organisation. In this session we will share best practices from Meet je Stad! and present some guidelines for using our platforms.

demonstration: Lukas Mocek - Sensor.Community - Open Environmental Data

We invite you to become part of Sensor.Community. - Build a sensor, collect Open Data, share it in a continuous stream with the global network and join forces in local Sensor.Community groups.
> 13.000 sensors in > 70 countries > data-points (January 2021)
The main website is available in 13 languages.

workshop: Egon Kastelijn - From actual measurements to social subjects

Citizen initiatives try to measure air quality as good as possible.
Sometimes a measuring station/environment locally shows a clear deviation.
This can have a technical reason, and be a measurement error, but there may also be a real cause.
It is quite easy to determine the size of the deviation.
Sometimes it is also possible to locate the actual cause (particulate matter source), and sometimes with an accuracy of meters.
And with some effort, it can also be determined over what distance the air quality is affected.
This means that a measurement initiative may even be able to identify a possible pollution sources.
But then?

-> SMAL Zeist has always set itself the goal of measuring as accurately as possible, and not to interfere with measures and policy.

The questions we ask ourselves in this open discussion:
* Do you really want to be able to identify local sources as a citizen measurement initiative?
* Is it desirable that citizens' initiatives can locate sources of particulate matter in such detail?
* What conclusions can / may you draw based on raw measurements?
* What position do you want to take as a citizens' initiative?
* Do you want to use actual measurements for the personal interests of participants?
* What if you have a neutral approach yourself, but third parties enter the barricades with the same measurement data?
* And if you, as a measurement initiative, would choose to take an active role, what is and what is not desirable?
