Hello!I am Szymon PifczykI am a mapmaker, I dry imaginary towns and I became a journalist by a total coincidence

WHAT DO I DO?
And, consequently, why am I here!
1.WHY DID I START MAKING MAPS?
“All the good things, they come from America”
- a man with a truly tremendous haircut (he most likely said it)

NOT ALL THE GOOD
THINGS COME FROM AMERICA!
- the world
After all, charts work just as well,
don’t they?
2.WHY ARE
MAPS GREAT?
Maps show what spreadsheets and
charts hide
Making them is usually free and sometimes other firms will pay you
to do so
Some data just has to be presented on
maps
You can produce your own data
Maps are great for showing culture
and societal phenomena
Sometimes even the most common
data turns out interesting
Maps are great for displaying large
datasets
And sometimes they just look
beautiful
Okay, maps are awesome but so what?
3.WHAT’S IN IT FOR
MY BUSINESS?
60,000 That’s how much faster we process visuals compared to texts
2xThat’s how many more likes does a photo get on Facebook compared to text status
94%That’s how much more views are attracted by content with large visuals compared to content with no visuals

MAPS ARE BIG AND COLORFUL
VISUALSand people - particularly people
on the Internet - are attracted to color
EVERYONE’S DOING IT
The New York Times’ Upshot has set a high standard for visualizing data on maps and other news outlets such as The Washington Post, Guardian, Die Zeit and others follow the lead.

But how do I start?
4.OKAY, YOU’VE
CONVINCED ME
WHAT DO YOU NEED?
GIS software
Geographical data
Statistical data
MOST-COMMON GIS SOFTWARE
ArcGISThe behemoth created and developed by Californian firm ESRI. Commercial, costs a lot of $$$. Impressive capabilities.
QGISAn open-source alternative to ArcGIS. Free, a little less capable but completely enough for most non-professional users.
RStatistical package R offers some GIS components and can create amazing maps but imho the required coding effort is too heavy compared to the outcome in most cases.
the coolest of them all:QGIS
➜ Lack of data - in particular geographic data (shapefiles and similar)
➜ Low granularity of data➜ Beginner’s mistakes
