A common requirement for processing vector data is to tile (or tesselate) a vector object into a series of regular, non-overlapping squares or rectangles so that the entire object is covered. A function to do this is described as follows:
Create Or Replace T_Geometry As Object( […] Member Function ST_Tile(p_Tile_X In Number, p_Tile_Y In Number, p_grid_type In varchar2 Default 'TILE', p_touch In Integer default 0, p_clip In Integer default 0) Return T_Grids Pipelined,
This function requires the width of the tile in X and Y dimensions to be provided. They do not have to be the same. They, however, have to be expressed in the default units of the geometry's SRID. In addition, the
p_grid_type parameter allows the user ...
