Using Geodata and Geolocation in the Social Sciences: Mapping our Connected World provides an engaging and accessible introduction to the Geoweb with clear, step-by-step guides for: • Capturing Geodata from sources including GPS, sensor networks and Twitter • Visualizing Geodata using programmes including QGIS, GRASS and R Featuring colour images, practical exercises and a companion website packed with resources, this book is the perfect guide for students and teachers looking to incorporate location-based data into their social science research.
Chapter 8: Geocoding, Geotagging, and Geoparsing
Geocoding, Geotagging, and Geoparsing
This chapter includes:
- Three practice exercises on geocoding
- Two practice exercises on geotagging
- Three practice exercises on geoparsing
As we saw in the previous chapter, absolute location data in the form of coordinate pairs are an essential building block of the geoweb. By providing us with a universal language of space (translatable, but consistent, across many different map projections), the geographic coordinate system gives us the ability to pinpoint a location on Earth quickly and easily. The increasing ubiquity of GPS receivers and the wide variety of software applications that can interpret and map coordinate pairs mean that more and more of the data we generate include some type of geolocation information.
Yet there is also a large amount of geospatial information ...
