In this third tutorial, we scrape the incoming text messages for pairings of strings in the format “key:value value …”, which we parse out with a regular expression and store in a separate Keyvalue table. This allows us to intelligently search and manipulate the data, as well as to geocode addresses submitted along with data. This yields latitude & longitude data for a given text message.
