Visualizing social issues using MUSUBU maps (multi-layered integrated maps) (Disaster prevention edition)

An attempt to create a new disaster prevention and mitigation map by integrating old and new map data for Shiga Prefecture (Omi)

Abstract

The occurrence of various natural disasters can be read from records and expressions such as old maps and illustrations related to Shiga Prefecture. Since the Meiji period, progress has been made in creating maps based on viewpoints, so it is now possible to roughly understand the topography around Lake Biwa. Since 2013, when the Geospatial Information Authority of Japan began a service for viewing maps and aerial photographs, it has become easier to create individual maps for specific purposes. I would like to integrate this variety of new and old information (maps) and lead to new awareness and analysis. Or, by reading the thoughts, wisdom, and ingenuity of our ancestors, we want to grasp clues to solving problems in today's society.
