This course

Quiz

• Can you think of a real-world context where data and statistics are being used to make a difference?
• Have you ever heard the term "Big Data"?
• Have you ever heard the term "Data Science"?
• Have you ever written a line of computer code?

Philosophy

• (Lots of) methods and techniques
  • General overview
  • Intuition
  • Very little math
  • Lots of ways to continue on your own
• Emphasis on the application and use
• Close connection to "real world" applications

Logistics - Format

11 weeks of:

• Prep. materials: videos, podcasts, articles... 1h. approx. (most recommended!)
• 1h. Lecture: concepts, methods, examples
• 2h. Computer practical: hands-on, application of concepts, Python (highly employable)
• Further readings: how to go beyond the minimum

Logistics - Content

• Weeks 1-3: "big picture" lectures + introduction to computational tools (learning curve)
• Weeks 4-8: "meat" of the course (lots of concepts packed)
• Weeks 9-11: catch up + prepare an awesome Assignment II

Code

"Even if you won't be a poet, you need to know how to write"

Python

Python

• General purpose programming language
• Sweet spot between "proof-of-concept" and "production-ready"
• Industry standard: GIS (Esri, QGIS) and Data Science (Google, Facebook, Amazon, Netflix, The New York Times, NASA...)

Self-directed learning (or "it's all about YOU")

Prepare for the labs

• I won't be leading/lecturing at the computer labs
• Go over the notebooks between the lecture and the computer lab --> If the first time you see a notebook is at the lab, you won't be able to follow on
• Bring questions, comments, feedback, (informed) rants to class/labs
• Use the forum (link on VITAL)
• Collaborate with your peers (it's NOT a zero-sum win!!!)

More help!!!

This course is much more about "learning to learn" and problem solving rather than acquiring specific programming tricks or stats wizardry

• Learn to ask questions (but don't expect exact answers all the time!!!)
• Help others as much as you can (the best way to learn is to teach)
• Search heavily on Google + Stack Overflow

Assignments

• Mark (mostly) based on two assignments, due:

  1. Week 7 (47.5%)
  2. Week 12 (47.5%)

• Coursework

• Equivalent to 2,500: report (notebook) with code, figures (e.g. maps), and text

The (geo-)data revolution

The (geo-)data revolution

Exciting times to be a:

• Geographer
• Map fan
• Data fan

The world is being "datafied"...

"Datafication"

“taking all aspects of life and turning them into data” Cukier & (Mayer-Schoenberg)

Examples: credit transactions, public transit, tweets, facebook likes, spotify songs, etc.

"Datafication"

Many implications:

• Opportunities for optimization of systems (Industrial IoT, planning systems...)
• Window into human behaviour (this course)
• Issues with intentionality and privacy
• ...

Why now?

The (geo-)data revolution

The confluence of the three (computing, communication and geospatial) is creating large amounts of data.

Now, data in itself is not very valuable:

• Data --> Information --> Knowledge --> Action

Statistics + ...

Some examples...

Geo-Data Science

Geo-Data Science

• A (very) large portion of all these new data are inherently geographic or can be traced back to some location over space.
• Spatial is special.
• Some of the methods require an explicitly spatial treatment --> (Geo-)Data Science
