| Abstract: | The research focus on the approach for realizing alternant query function between spaces and property in the application developed based on GIS components.Several different realizing processes of practical query methods from spatial information and property information had been contrasted and analyzed .Several ways to improve the query efficiency by using MapX as the component to construct a GIS system was discussed.Simultaneity,the practical problems of property query with MapX4.0 were pointed out,and the concrete scheme for solving these problems was also suggested. |

| Keywords: | GIS MapX software component spatial object property query |
