tiles - Tiling Vector data without losing geometrical and topological information


I am trying to figure out a way to sub-divide a vector based map into smaller blocks. I can tile the map based on different strategies such as q-tree. However, it is unavoidable to cut some polylines and polygons that cross the boundaries of the blocks. By doing this, we will lose their geometric and topological attributes.



The tiled data can only be used for display but not for spatial analyses because they have partly lost their geometric and topological attributes. Do you have any suggestion or experience with sub-dividing the vector data and still maintaining their us usability for spatial analyses?
