## Introduction

Main Messages
- Geospatial data are relevant in the social sciences
  - already for a long time
- `R` can serve as a full-blown Geographic Information System (GIS)

## Vector Data

Main Messages
- Most common geospatial data type
- Vector data come as points, lines or polygons 
- Information on the geometries stored in the geometry column
- Attributes can be assigned to each geometric object
- Attribute tables are treated as data frames

## Basic Maps

Main Messages
- basis of each map is the geometries of geospatial data.
- spatial distribution of attributes become visible when  defining an attribute and adding color scales
- layer shapefiles to add more information or for aesthetic reasons

## Raster Data

Main Messages
- Data format for efficient and fast analysis of geospatial data
- flexible in their application
- methods of image processing can be used
  - can get rather involved
- however, straightforward extraction of values

## Advanced Data Import

Main Messages
- Geospatial data tend to be large
- Often distributed over the internet
- APIs help in downloading these data
- can get pretty involved

## Applied Data Wrangling

Main Messages
- Georeferenced survey data require handling sensitive data
- our example of wrangling and linking data (applications may vary)
- spatial joins are the perfect tool to add geospatial information to other georeferenced data

## Advanced Maps I

Main Messages
- When making maps think not only about map layers but also layers of meta information and visualizations
- Advanced toolboxes like ggplot2 allow you to tweak every detail of your map.
- Making maps can be very time investing but yet very rewarding

## Advanced Maps II

Main Messages
- Drawing maps as in Powerpoint...
- it's coded and thus reproducible
- ...and fun?

---

## What's left

Spatial Analysis
- requires knowledge of spatial statistics
- but definitely the next step

Other map types
- cartograms
- hexagon maps
- animated maps
- ...

More data source
- necessarily limited

---

## Data Sources

Some more information:

- geospatial data are interdisciplinary
- amount of data feels unlimited
- data providers and data portals are often specific in the area and/or the information they cover

Some random examples:

- [Eurostat](https://ec.europa.eu/eurostat/web/gisco/geodata)
- [European Spatial Data Infrastructure](https://inspire.ec.europa.eu/about-inspire/563)
- [John Hopkins Corona Data Hub and Dashboard](https://coronavirus.jhu.edu/map.html)
- [US Census Bureau](https://www.census.gov/geographies/mapping-files/time-series/geo/carto-boundary-file.html)
- ...
