Thanks to
For your resources
what is qgis and why should i care?
geographic information system
(in other words, it's software that allows you to open geographic files, edit them, analyze them, and make maps)
FREE
That's generally good, right?!
OPEN-SOURCE
Also generally good
Let's get to know the interface
Map view
Manage Layers
Status bar
Tool bars
(Yours might look slightly different.
That's OK.)
Adding/Removing Tool Bars
let's make a map!
But wait, what are we making a map of?
Before we can make a map, we need to get data.
Great for general reference data
Lots of worldwide datasets used in development
(with decent data from previous years, too)
Downloads:
Countries (from Natural Earth)
GDP per capita (original link from World Bank here)
Adding data
1. Add vector data
(countries)
2. Add CSV data
(GDP per capita)
Adding your CSV
Projections
Now we need to connect our GDP data to our map data.
Examine our attribute tables
Open Attribute Table button
Right-click on the layer
--> Open attribute table
Adding a join
Add Join
Adding a join, part 2
Save your new, joined file and add it to the map
