Cover Story: Precise georeferenced data are crucial for relevant demographic, economic, and social analyses. Obtaining the location of specific events is now highly valuable. However, open-source geocoding tools are not always as efficient as desired. Our study reviews fifteen R packages and their interactions with various geocoding service providers. We used the following three metrics to evaluate them: time elapsed, number of missing values, and the distance between the coordinates included in the original dataset and those obtained by geocoding. These metrics were derived from a sample of 15,000 postal addresses from the street map of Madrid. As an alternative method, we propose web scraping to improve data accuracy and fill in gaps, aiding researchers and social agents to incorporate geospatial information into their data, enabling more comprehensive analyses.

This work shows the original projection of a 1:57,600 scale map of southern Germany at the end of the 18th century, produced under the direction of Karl-Heinrich von Schmitt (1743–1805). The sections of the map were scanned and georeferenced as...
