In 1569 the Flemish cartographer and mathematician Gerardus Mercator published a new world map under the title “New and more complete representation of the terrestrial globe properly adapted for use in navigation.” The title of the map points to Mercator’s main claim for its usefulness, which he expounded upon in the map’s legends. Mercator presented his map as not only an accurate representation of the known world, but also as a particularly useful map for the purposes of navigation....| A Rogue Historian
The previous post provided an introduction to the sp and sf packages and how they represent spatial data in R. There I discussed the creation of Spatial and sf objects from data with longitude and latitude values and the process of making maps with the two packages. In this post I will provide further background for the sf package by going into the details of the structure of sf objects and explaining how the package implements the Simple Features open standard. It is certainly not necessary ...| A Rogue Historian
The geographic visualization of data makes up one of the major branches of the Digital Humanities toolkit. There are a plethora of tools that can visualize geographic information from full-scale GIS applications such as ArcGIS and QGIS to web-based tools like Google maps to any number of programing languages. There are advantages and disadvantages to these different types of tools. Using a command-line interface has a steep learning curve, but it has the benefit of enabling approaches to anal...| A Rogue Historian
In the previous post I discussed some reasons to use R instead of Excel to analyze and visualize data and provided a brief introduction to the R programming language. That post used an example of letters sent to the sixteenth-century merchant Daniel van der Meulen in 1585. One aspect missing from the analysis was a geographical visualization of the data. This post will provide an introduction to geocoding and mapping location data using the ggmap package for R, which enables the creation of m...| A Rogue Historian
