Workflow

Choropleth maps on asylum applications (abs/rel)

1. Download world shapefile/geoJSON from the web (e.g. from thematicmapping)
2. Delete unnecessary columns (features):
   • convert to ESRI shape file
   • toggle editing
   • use click-based deletion of features
3. Download number of asylum applications and total population (both by country, 2008-2015) from Eurostat
4. Do some preprocessing in R and save the pop/immi data as csv (mergeData.csv)
5. Join in QGIS and export as geoJSON (alldata.geojson)
   • right-click on layer in layers panel -> Properties -> Joins
   • right-click on layer in layers panel -> Save as... -> under Format, select geoJSON

ZEIT article replication (map still under construction, only pie charts so far)

1. Here is the article link
2. Download replication data and convert to csv (attacks.csv).
3. Use Python (GetCoord.ipynb) to get coordinates since spreadsheet does not contain latlng (attacks_final.xlsx).
4. Steal incident type icons from original map (cf. article).
5. Use R to translate data set, summarize state of investigation, count within states, and make graphics.
6. Add new layers to map: incident type, state of investigation, summary per state.

Future projects

1. Finish replication of ZEIT map that displays attacks on refugee hostels.
2. Create map on migration routes and deaths based on data from The Migrants' Files.
