The underlying process that generates these discrepancies is usually unknown and is nonhomogenous in nature. The nonhomogeneity suggests that registration of the datasets should be performed using local transformations; the type of local transformations is, however, an open question. Usually, a local rubbersheeting transformation that utilizes nodes as counterpart features is applied to solve these discrepancies. However, pointbased transformation is adequate only for simple cases. This paper presents a local transformation algorithm based on counterpart linear features. The transformation is more general in essence and suitable to a wide range of cases, especially for transformation of spatial geographic data. The linebased transformation is presented here as part of a linearbased map conflation algorithm, a framework under which this transformation is most likely to be encountered in geographic information systems (GIS). Nevertheless it can also be applied separately as part of different applications.
