Hexagonal grid construction method for remote sensing satellite area observation task

The invention discloses a hexagonal grid construction method for a remote sensing satellite area observation task, which comprises the following steps of: 1) constructing a spherical hexagonal map grid subdivision model of a spherical icosahedron based on the digital earth, the zeroth layer of the spherical hexagonal map grid subdivision model subdivides the surface of the earth through n hexagons and Hp pentagonal grid units to obtain a zeroth layer digital grid map of the digital earth, center point coordinates and vertex coordinate values of each hexagonal grid and each pentagonal grid are fixed, and the side lengths of the hexagonal grids and the pentagonal grids are equal; calculating the central point coordinates and vertex coordinate values of hexagonal grids and pentagonal grids in the digital grid map of each layer from the first layer to the set highest layer of the spherical hexagonal grid subdivision model according to a set rule, and taking the central point coordinates and vertex coordinate valu
