In basic terms it is the process of taking several images across a flight plan and then using the images to create a 3D model of the area or object that you have taken the images from, these can be created to a scale or a general model.
3D mapping is most often used to survey land before a building permission application is sort and is much faster and more efficient then using a land based (human) method, not to mention much cheaper.
Surveys can range from roof surveys (see if work is required etc.), surveying old/listed buildings to surveying power lined.
Roof and structural surveys often require scaffolding and a team of people to perform the inspection but with a drone you can have 4K video that you can zoom right into and perform the survey/inspection that way saving funds and resourses.
You can also have a mix of both 3D mapping (3D model) and video drone surveys for that complete package.
Through the method of 3D mapping you create 3D models, now these models are very high in poly count and require quite a bit of work to bring the asset or 3D model to a poly count that is low enough to be used in video games of todays standards, often you have to split up the 3D map into several components to be used into the game development industry.
Things like trees have to be replaced as in 3D mapping it is next to impossible to get them to look good enough in a gaming environment.
