To oversee something or someone means to take charge and keep track of how things are going, often as a responsible person in a position of authority.
When we talk about overseeing, it usually means that you're in a leadership role where you have the power to make decisions and ensure that everything is running smoothly. For example, if your teacher asks you to oversee a group project, they want you to be in charge and make sure everyone is doing their part. It's like being the captain of a team - you're responsible for guiding them towards their goal. You might oversee a new employee at work, helping them get settled in and making sure they know what they need to do. Or, if you're planning an event, you might be asked to oversee the setup, making sure all the tables and chairs are in the right place. In general, overseeing means being in control and making sure things happen as planned.
To survey, look at something in a wide angle.
