  1. The digital map is usually formed by the water depth ' s database measured on the seabottom. because of the disadvantage that the database is kept secret, this dissertation introduces a new method : first, the depth data are picked up from the electronic chart, then interpolation of the depth datum by kriging algorithm is adopted to gain the digital map. the method is the precondition of the terrain matching when it is researched by simulation, and it is the complement of the database
