Online Geocoding of Millions of Economic Operators
Geocoding is the process of converting an address or a place name into geographic coordinates. This conversion process has become a fundamental subject in many scientific domains and real world applications, from health and crime analysis to route optimization. In this paper, we present our conversion process of over four and a half million, mostly Portuguese, economic agents, through their addresses or names. We also describe how this information can be useful to detect and remove duplicate information in databases. The results demonstrate the power, exibility and accuracy of many of today's online geocoding services.
