Abrégé

The invention relates to a sports field comprising a playing layer (1) laid on an underlayer (2), with the surface of said field being divided into two complementary sub-surfaces, the respective surface areas of which are both strictly positive, wherein: • vertically in line with a first sub-surface, the structure of said sports field is equipped with means for creating a layer (3) of liquid, such as, for example, a water table, in the volume of the sub-layer (2) located under the playing layer (1) and vertically in line with the first sub-surface, and for managing the level thereof; • the sub-layer (2) comprises a multitude of capillary trenches (4) located vertically in line with the first sub-surface, said capillary trenches being configured to ensure permeability and capillary continuity between the playing layer (1) and said liquid layer (3).

According to said method, from a local coordinate system (O; x, y, z), the grassed area (T) is digitised and a marking area (Q) is divided into elementary cells to form a matrix (M).; the pattern to be marked is broken down into a mosaic of pixels associated with the elementary cells of the matrix (M). Subsequently, for each elementary cell of the matrix, tasks to be performed by the marking means are determined according to a value of the pixel associated with the elementary cell, to mark the pattern to be marked on the marking area; and the movement of the vehicle (V) over the grassed area to cover all the elementary cells is controlled, as well as the marking means for carrying out the tasks to be performed in each elementary cell. Application in the field of advertising on the grassed area.
