In order to create meaningful information to improve population health, data need to be combined from different sources and aggregated by location. But there is a problem. Data from different sources are not compatible with each other. They do not have the same structure, do not use the same vocabulary, and do not use the same format to represent location. Some data use GPS coordinates while others reference location by name. It is resource intensive to reconcile these kinds of disparities in order to integrate data from different sources to find the information you need.
