Abstract: This paper studies the navigation and lattice and vector enlarging techniques of ECDIS with VC++ software. This thesis designs a ring-shaped window without flashing, whose function is very similar to an actual enlarging lens, and presents a searching algorithm to realize the vector enlarging by the vectorial characteristic of the source data. The actual result of the development proves the algorithm is effective and available.
