4 APPLICATION OF HISTORICAL MAPS
As the application of historical maps to GIS or virtual
archeology, city and scene modeling of historical row of stores
and houses on a street were performed using extracted the
attribute data. The detail procedures for modeling are as
follows:
1) The attribute data were extracted using mathematical
morphology.
2) Remapping were performed using TIN model and Affine
transformation.
3) Classification of the attribute data were performed by
overlapping.
4) 3D models of the typical samurai residences were
reconstructed using 3D CG soft ware.
5) 3D models of the typical townsman houses were also
reconstructed using 3D CG soft ware.
6) The historical map and the 3D models were connected by
authoring soft.
7) The historical map and current map are appeared upper parts
on the monitor using menu command, scene model of the
Figure 16 Remapped historical map in 1694
historical row of stores and houses on a street are appeared
lower parts on the monitor by clinking the some point on the
historical map. Similar, the current picture corresponding to the
same point are appeared on the monitor.
8) City models are also obtained by menu command.
Figure 17 shows scene model and figure 18 shows city model.
These are simple example, but people can appreciate several
scene and city models form various view points.
5 CONCLUSION AND FURTHER WORK
In order to utilize historical maps to GIS or virtual archeology,
the extraction and classification method of the attribute data
which exists in historical maps were described using
mathematical morphology and TIN model. The remarkable
points of this paper are its ability to apply historical maps to
GIS and virtual archeology, and these application examples
were also demonstrated in this paper.
There are issues, however, for further work. These problems
include extracting special area such as boundary lines or small
characters and insufficient clarity color.
