OGIS is a set of public space data manipulation functions, which can be applied in any platform and system, making it possible for the users to use in a sole environment and a work flow and being suitable for any geography data distributed on the net. But the OGIS function collection is imperfect. It cannot provide unified standards for space data conversions of various levels and fields and it cannot completely solve problems of data centralism and distribution processing. By using the computer-aided design data processing method, this paper realized the computer-aided design data batch transformation and processing. It took the topographic diagram as the data pool to instance demonstrated and provided a feasible plan for the computer-aided design topographic diagram transformation which can maintain the data well the precision and the integrity. The example proved that the method used in this paper has realized fast loss less transformation for the spatial data, which has a broad application in relative field.
