We developed a climbing plan sharing system. While climbing plan documents that have been created in Microsoft Word or PDF format have a lot of climbing information, a computer cannot understand climbing information efficiently because the climbing information is written in a natural language. We developed a system that converts a climbing plan document into a machine-readable climbing plan. Also we have implemented a function to share climbing plans among users. The system can display a climbing plan on a Web browser effectively. Our system can help climbers to share machine-readable climbing plan documents. Therefore, users can share and accumulate climbing information that are difficult a climbing plan document written in a natural language.
