1. Associating Coordinates to Patients 1 ) Patient address goes into the system 2 ) If the address is valid then get the coordinates 3 ) Associate the coordinates to the patient's address umudugudu_id latitude longitude 0104020507 -1.9534521 30.651238 … … … address_id precision lat lon 34 1 -1.9534521 30.651238 … … …

2. Associating Coordinates to Patients This patient's coordinates were derived from their address This patient's coordinates were collected at their house with a gps device address_id precision lat lon 34 1 -1.9534521 30.651238 237 0 -1.9812122 30.234525
