Abstract :
This paper discusses traditional development models of GIS and proposes another model, geographical information system shell (GISS). Following the thought of GISS, a geographic information query tool (GIQT) is developed. GIQT\´s main purpose and menu structure are introduced, as well as the classification and encoding. This paper especially describes the implementation of "two-direction multi-function query" and "compressed tree-like binary search" in length. The indexing mechanism and search method greatly improve the efficiency of GIQT\´s functions
