Determining the location of the station occupied by a plane table on a map is called resection. Resection is a surveying technique that involves using known points on the map to determine the location of an unknown point. This technique is commonly used when conducting topographic surveys or mapping.

Resection involves the following steps:

1. Set up the plane table: The plane table is set up at the station whose location needs to be determined. The plane table is a portable drawing board equipped with a sighting device, such as an alidade, and a level.

2. Orient the plane table: The plane table is oriented so that its reference lines align with the north-south and east-west directions. This can be done by using a compass or by sighting a known point on the map.

3. Sight known points: Using the sighting device, the surveyor sights at least two known points on the map. These known points should be visible from the station occupied by the plane table. The angles between the sighting lines to the known points are measured using the alidade.

4. Plot the known points: The measured angles are then used to plot the known points on the map. The lines representing the sighting directions from the station to the known points are drawn on the map.

5. Determine the station location: The intersection of the lines representing the sighting directions from the station to the known points determines the location of the station on the map. This intersection point represents the position of the plane table station.

Resection is a useful technique in surveying as it allows for the determination of the location of a station without the need for direct measurements to that station. Instead, it relies on the measurement of angles and the use of known points. By applying resection, surveyors can accurately map out an area and obtain the coordinates of various points of interest.
