  In this paper, we reviewed the notes on using Web map image provided by Web
map service, from the viewpoint of copyright act. The copyright act aims to
contribute to creation of culture by protecting the rights of authors and
others, and promoting fair exploitation of cultural products. Therefore,
everyone can use copyrighted materials to the extent of the copyright
limitation based on copyright act. The Web map image, including maps, aerial
photo and satellite image, are one of copyrighted materials, so it can be used
within the limits of copyright. However, the available range of Web map image
under the copyright act is not wide. In addition, it is pointed out that the
copyright act has not been able to follow the progress of digitalization of
copyrighted materials. It is expected to revise the copyright act corresponding
to digitalization of copyrighted work.
