*5.1. Analysis of Inconsistent Parcels*

Figures 13 and 14 show the detailed results in two enlarged zones of Site 1 and Site 2, respectively. Some land parcels registered as "building site" on the cadastral system (i.e., designated for building construction) contained no buildings in the real dataset. These parcels often remained as a ground covered only by low vegetation. Thus, the discrepancy ratio was high in parcels of building sites in the cadastral map, but which were classified as crop land or bare soil in subset-1 of Site 1 (Figure 13a). Moreover, it was high in parcels of parking lots in the cadastral map, but identified as buildings in the land cover map. On "road," where the item of the cadastral map exactly matched the class of the land cover, the discrepancy ratios were increased to moderate because the boundaries were sharp on the cadastral map but fuzzy on the land cover map (the roadside trees were included in the road parcels). Although some parcels with more than 50% of discrepancy ratio were detected as candidates of updating, because of misclassified pixels, they showed a relatively low discrepancy ratio compared to other inconsistent parcels. In subset 2 of Site 1, the discrepancy ratio was high in the central part of the image because many parcels were registered as "reservoir" in the cadastral map but were actually crop land in the land cover map (Figure 13b).

In subset 2 of Site 2, some parcels were moderately inconsistent, identified as "paddy field" in the cadastral map, but as bare soil in the land cover map (Figure 14b). In a similar case of subset 1 of Site 2, the discrepancy ratio was high in areas identified as "paddy field" in the cadastral map, but classified as not only bare soil but also buildings in the land cover map. It seems that buildings were constructed on this site (Figure 14a). Moreover, if the vegetation index is low at the image acquisition time, paddy fields can be classified as bare soil.
