摘要：In this paper, we present a model to identify building shapes based on different spatial information in GIS. This model uses the overlapped area of building shapes for the identification. Two building shapes with different spatial information are identified as the same building when the ratio of the overlapped area of these two building shapes is over the threshold value. However, on the other hand, many studies have been made concerning the influences of GIS modeling errors, and considering these positional errors of GIS becomes essential when we apply this model to real GIS data. For this reason, first, we estimate the error for the area of a building shape projected on spatial information with positional errors. Next, we estimate the errors for an overlapped area of two building shapes with the same original shapes, which are based on different spatial information to show a method of determining the threshold value. This identification model is then applied to actual GIS data and compared with other methods.
