Embodiments of the present invention provide for accurate relative location information to be preserved between vector and raster data sources during non-linear transformation. In a method according to an embodiment of the present invention, raster and vector data are received that corresponds to maps and conflated in a multi-step process. Objects of at least one of vector data are identified and conflated. For example, in an embodiment of the present invention, vertices of vector objects are identified. In a subsequent step, raster data is conflated by applying a non-linear transformation to the raster data using identified vertices of vector data from before and after conflation as control points. The resulting hybrid map is output that is advantageously accurate in general but is further advantageously accurate at critical points. |
