The New Geo

 

oder:

 

Warum Geo heute weit mehr ist als GIS

Daten

- AUSGANGSPUNKT: UNSERE STÄDTE SIND HEUTE RIESIGE DATENMASCHINEN

- Daten erlauben es, unsichtbare Vorgänge sichtbar zu machen und räumliche Muster zu erkennen

 

- Neue Datenquellen ermöglichen dies, oftmal sind diese Daten offen (open data) oder wir müssen sie erschließen (APIs, hidden APIs), etc.

 

2. Thema:

Geo und moderne Dataviz heute (3 trends: alles online, mehr offenheit (or not), Geo communities (z.B. OSM, Maptime, UCLab)

3. Beispiele ich

4. Beispiele UCLab

- Kommunikation/ Marketing

- Forschung/ Research/ Exploration

- Analyse vs. Visualisierung

 

 

- Innovative Analyse, Methoden und neue Visualisierungstechniken von Geodaten

- Visualisierung urbaner Mobilität (Beispielprojekte)

Airbnb vs. Berlin

1.0

2.0

Background:

  • Student project at the University of Applied Science, Potsdam, early 2015
  • Storytelling with Data and Design
  • Idea: Find a topic that is of personal interest to us: Lucas and Alsino were looking for a flat at the time in Berlin

"Why don't you just move into one of those Airbnb flats?...They are super easy to get..."

(a friend)

THE QUESTION

Is Airbnb (partly) responsible
for the shortage of affordable housing in Berlin?

THE PROBLEM

Very emotional discussion

Not based on facts

Data?

Results

(what happened earlier...)

AIRBNB HOSTS ARE

IN FOR THE €€€€

REACTIONS:

(18.3.15 17:08 – 50 Minutes after launch)

 

Email from Airbnb:

"Dear students, who is responsible for this data generation and where did you get the data?"

"[...] We would like to do an interview with you about your study. It is pretty much advertising for Airbnb, because we would like to show the situation as it is

(and it's true, the platfom is booming right now). [...]"

(a big German tabloid)

(20.3.15 17:08 – 2 days after launch)

Fast forward: 1 year later

Law against misappropriation of housing space:


- forbidden to temporarily sublet > 50% of flat space

- landlord agreement required

- enforced from 1 May 2016

- fines up to € 100.000 in case of violation

- "fuzzy" legal description: different city districts handle it differently

So, what are the consequences?

Only slight and temporary drop in listings

​(and almost back to pre-law level)

A few learnings from the project

Data + visualization

 =

Powerful tools

1. Explore

Data can be hard to get, but essential for an informed debate

2.Debate

Regulation needs to be targeted "well" to address the real issues

3.Act
