【Abstract】 Some spatial operators provided by spatial module of Oracle 10g,among them,some can be invoked directly and others must be invoked indirectly.By saving the result that created by realizing these spatial operators based on OO4O and further processing the data that obtained from the saving result with MapX,the capability of spatial operators if development system is improved.更多还原
