Automatic geocoding methods have become popular in recent years, facilitating the study of the association between health outcomes and the place of living. However, rather few studies have evaluated geocoding quality, with most
of them being performed in the US and Europe. This article aims to compare
the quality of three automatic online geocoding tools against a reference method. A subsample of 300 handwritten addresses from hospital records was geocoded using Bing, Google Earth, and Google Maps. Match rates were higher
(> 80%) for Google Maps and Google Earth compared with Bing. However, the
accuracy of the addresses was better for Bing with a larger proportion (> 70%)
of addresses with positional errors below 20m. Generally, performance did not
vary for each method for different socioeconomic status. Overall, the methods
showed an acceptable, but heterogeneous performance, which may be a warning against the use of automatic methods without assessing quality in other
municipalities, particularly in Chile and Latin America. [-]
