Crowdsourcing and the IoT: new ways of collecting data about the city

Kuva_AapoRista

It’s important for officials to have the most accurate and broad information possible about their domain of operation. In tune with this sentiment there are many ongoing ventures by the city of Helsinki and other organizations to explore new ways of collecting data, especially using distributed or moving sensing technology (ie. IoT) as well as utilizing regular people as data collectors (i.e. crowdsourcing). On 2nd of March 2017, Laituri saw a variety of speakers and crowd eager to know about the activities of the City of Helsinki that lie under these umbrella terms.

Available public spaces! Integrate them into your service?

Vallilan_kirjasto

Cities possess hundreds of public spaces, premises and equipment – for example, the City of Helsinki has about 3000 buildings. Use of public spaces can be optimized but it requires real-time availability and reservation information. Now, with Helsinki’s recently opened resource reservation API, relevant information on the availability of a selection of the city’s public spaces is available.

Public spaces and resource reservation methods was the theme of first Helsinki Loves Developers open data open office in 2017. Participants brainstormed improvements to data collection methods and discussed methods for optimising collected information of available public spaces.

Information about Finland shared through an open API in many languages

Infopankki_logo

The text contents of the Infopankki.fi website have been opened for everyone to use through an open application programming interface (API). The website contains important information for immigrants about permit matters, working life and entrepreneurship, studying Finnish, housing and living in Finland. All of the 12 identical language versions of the service are available through the API. Infopankki contains approximately 3,500 web pages.

“We hope that Infopankki materials will be used to create applications that serve the information needs of immigrants in different languages.

New generation city information models for Helsinki

3dmalli

As the first city in the world to do so, Helsinki has simultaneously introduced two 3D city models covering the entire city: a smart semantic city information model and visually high-standard reality mesh model. The models are being released as open data.

A semantic city information model is more than a three-dimensional image on a computer screen. The model objects contain property data about themselves. By means of semantics, the computer understands, for example, which elements describe the roof or walls of the building.

What about documentation?

models_width-535

As most of us know, coding is a busy business. New ideas, feature requests, crucial hotfixes, standard bugfixes and a number of other issues pile up in addition to planned projects and sprints. Therefore, when developing an API for your own use, you are usually satisfied once you get it to work the way you want, and move on to the next pressing thing to do. After all, we are using our own API, why should we bother with systematic specification and documentation of the features we know and are able to check from the source code whenever we want?

Combining datasets improved findability

HRI_STILL_006_FIN

Almost 1300 datasets in January, around 600 in February and now the counter on the frontpage of HRI shows 549. Good grief, has HRI begun deleting data? Not exactly, but a large operation of re-organising HRI’s datasets, which involved combining and harmonising datasets where possible. No data has been lost, the previous 1300 datasets are now available in larger packages.

At the start of the year, HRI began the large task of clarifying the contents of its data catalog, which involved combing through smaller datasets and combining them into larger packages.

Restful data

parking_width-800

Well-formed data at rest is as close to perfection in programming as it gets. All the crap that had to happen to put it there however..

Rufus Pollock from Open Knowledge Foundation visited our Helsinki ❤︎ Developers meeting during OKF’s MyData conference. He introduced us to the idea of frictionless data; making open data easier to discover, use and understand. Basically is a way to describe data using machine readable, yet lightweight and even human writable format based on JSON and bundles it alongside a universally supported format for data: comma separated file, CSV.
