1. Method of electronically tracking of spray coating of a coating fluid on a physical surface by a spray gun arranged to spray the coating fluid in a spray direction, the method comprising, in an electronic computing system:
receiving, from a distance sensor module connected to the spray gun and comprising at least one distance sensor, distance data provided with a second timestamp, the distance data indicating a physical distance between the spray gun and the surface;
obtaining, from an electronic memory, three-dimensional coating model data of a spray cone associated with the spray gun;
receiving, from a positional sensing system connected to the spray gun, position data provided with a third timestamp, the position data providing an indication of the spray gun relative to a first position on the physical surface;
obtaining coating fluid flow data provided with a first timestamp, the fluid flow data providing an indication of a mass flow rate of the coating fluid through the spray gun;
adjusting the three-dimensional coating model data based on the coating fluid flow data;
synchronizing the coating fluid flow data, the distance data and the position data over time based on the first timestamp, the second timestamp and the third timestamp;
calculating, based on the synchronized distance data, the position data and the adjusted three-dimensional coating model, coating deposition area data of positional spray coating deposition on an area of the physical surface per unit of time; and
calculating, based on the coating deposition area data of positional spray coating deposition on the area of the physical surface per unit of time, thickness of a layer of coating fluid on the physical surface.
