We learned how to do things like filtering, faceting, normalizing data, removing duplicate rows and other pretty common tasks. In this article we will see how to use OpenRefine to enrich our datasets with data from any web service available on line. We will geocode each contact using google maps web service. For each address we will get the whole json response and we will learn to parse it, extract the coordinates, and save them in a latitude and longitude columns. This is how our dataset looked like after all the cleaning up we did in our previous article. You can see that we have an address column that we are going to use for georeferencing. A good advice before georeferencing a dataset, is to pick a couple of known addresses and test them on the web service. In our case, all the addresses are from Buenos Aires, Argentina. The formula is pretty simply.
