Introduction
• Urban Structure Visualization
Promotion Organization
– Established in 2018 to promote visualization of urban
structure in Japan
– OGC member from 2019
– Member from various sectors (public, private and
academic) join together to develop tools for urban
structure visualization

• Urban planning has been contributed to healthy urban
environments, prevented disorganized urban sprawl, and
also encouraged infrastructure development.
• However…because of population decline and aging
society,
• New social issues such as a rapid increase of empty
apartments and lands, and non-universal design of
facilities depend heavily on the sustainable development,
especially in regional areas.
Background
Urban areas are facing
a big turning point !

• Efficient urban management is required to
address local issues.
• Compact urban development is the way to go
from the perspective of administrative costs.
• Information-intensive activities for consensus-
building have become very important to call for
investment.

• An information infrastructure for urban
revitalization:
– to represent more clearly the situation in a particular
region, not just to data experts but also to people
without specific knowledge.
– to encourage consensus-building among relevant
stakeholders.
• Japanese government has been working on its
development, utilization, and promotion.
– In accordance with "the Basic Policy for Urban
Renaissance amended" in 2014 etc.

• Municipalities conduct various statistical surveys.
• Statistics are merely strings of numbers and hard
to understand
• Regional characteristics and topics can be
identified with one look.
• Change over the years can be presented.
• Comparisons with other regions is also made
possible.

• i-UR1.0 defines objects of 4 categories;
– Detailed information of city objects,
– Constraints/conditions (e.g. regulation),
– Statistical objects (grids) and
– Global city model for global analysis and
visualization
