ISPRS Workshop on Service and Application of Spatial Data Infrastructure, XXXVI(4/W6), Oct. 14-16, Hangzhou, China 
is the main idea to realize interoperability by means of editing 
the Oracle metadata using program or manual . 
4. SUMMARY 
It is a trend that spatial data is stored into object relation 
database. But many technical problems need to solve for really 
realization of interoperability and data sharing .We have 
finished this kind of system for three cities in HEBEI province, 
China, and inputted the data about 6000 sheets in 1:500 scale 
maps into Oracle Spatial. Also the data in Oracle Spatial 
database can been accessed directly by Maplnfo and AutoDesk 
Map each other using this method of editing Oracle metadata. 
But it is not easy way, and further study has still been done.
