Obtaining test data
Before we start importing, let's get some data examples in different formats, specifically these:
- Earthquake data in CSV and KML format (https://earthquake.usgs.gov/earthquakes/map/)
- UK Ordnance Survey sample data (https://www.ordnancesurvey.co.uk/business-and-government/licensing/sample-data/discover-data.html)
-
- AddressBase in CSV and GML
- Code-Point Polygons in SHP, TAB and MIF
- Points of Interest in TXT format
- NaturalEarth (http://www.naturalearthdata.com/downloads/110m-physical-vectors/)
-
- 110M coastlines
- 110M land
- 50M Gray Earth
You may either download the data using the links provided or find it in this chapter's resources.
The location you extract the data to is not important really, as you can later address it using either relative or absolute file paths.
