Positioning
Positioning is the accurate determination of the location of an object in space, relative to a framework or datum. In geographic / hydrographic information positioning is always present to determine the location of whatever we are measuring.
Depending on the type of application the framework can be global or local. When used globally techniques such as GNSS are used and the framework is defined by geodetical coordinate reference systems. Local positioning can be done on a jobsite such as in construction and engineering with total station but in for indoor navigation.
