Abstract :
One of the key elements of the data integration process is conflation of spatial data from two different sources, which results in a single data set that incorporates data and attributes from both sources. Registration techniques needed for conflation can be rigid or non-rigid, depending on the underlying transformation. A key characteristic of rigid transformation is that all distances are preserved.
