The signal-phase-matching principle of three and multi sensors are proposed in this dissertation. By using these principles, the formulae of estimated spatial signal are derived. The physical meaning and the geometric interpretation of these principles are given. The performances of estimated signal are analyzed when the phase of expected signal and the amplitude of noise are fluctuant.

Rule-based and reusebased method is adapted in our system to develop applications. Rules are used to define geometric representation of geographic objects, spatial relationships among geographic objects and map design rules. Reusability is realized through object's inheritance and encapsulation. The basic function related to GIS has been implemented in OOGDB's basic class base. Application related function can be implemented in sub-classes of basic classes and some of basic class' function can even be overloaded.
