（Term：2010 - 2011）
- Joint Seminars in 2010-2011 Fiscal Year
- Outline of Joint Research
- “Urbanization and Sustainable Development of Hanoi” aims to clarify human
behavior and society of urban Hanoi together with studies on natural terrain,
environment, subsurface structure in the Red River delta in Vietnam. In
order to carry out the project, an area-informatics approach will be introduced
based on spatiotemporal analyses by adding historical research on the transformation
from the traditional city form to its present "Modern age" city
formation since the 19th century. In particular, this IPCR program project
aims to examine the aspects of "Water" and “Geologic Structure”
from the view point of sustainable development in Hanoi.
- Purpose of Joint Research
-
The project has two aims; (1) to clarify the urbanization and transformation
of Hanoi with separating three periods such as before 1873, being under
French colonial, and after French colonial periods for the process of transition
and transformation in local communities associated with village location,
boundary, and facilities; (2) to analyze aspects of human and social behavior
by integrating features on the ground, the surface, and the subsurface
structures based on the studies on natural terrain and environment, phenomenon,
and underground structure, and the Red River delta with analyses of the
geological features on the boring investigations of the hydrological environment
and the Red River embankment construction. In particular, this project
focuses on the hydrological environment in Hanoi during 15 years since
1995 to analyze the dynamism of human behavior associated with the water
control system and water routes in the subsurface structure. This project
seeks a sustainable way of thinking about aspects of the urban development.
In past urban studies, most focused on individual and independent discussion
on the physical environment and its accumulation, human behavior, phenomenon,
and so on for urban areas. Therefore, this project will contribute to providing
an integrated clarification for urban studies adding the natural environment,
natural terrain, and the social environment on to a historical axis (time
axis) to a spatial aspect. It is hoped that this research will lead to
the creation of a new paradigm in area studies through integrating historical
space, micro-topographical change, the subsurface structure, and urban
foundations.
- Outline of Result
- In this year, we have studied the following researches with the aim of creating a base of geographical data;
(1) Generating of High resolution DEM
(2) Generating of GIS polygon data of building
(3) Analyzing of boring data
(1) The DEM of Hanoi was generated from the elevation survey data. The very subtle elevation gaps which cannot be distinguished on the satellite images are significantly recognizable on the DEM. These high resolution DEMs are useful not only for analyzing the urban transformation of Hanoi, but also for the urban sustainability of Hanoi, as in improvement of urban infrastructure and disaster prevention. (2) The polygon data for 3 dimensional GIS was generated from the compartmental building map. The present landscape was visualized by GIS software. And, the 1885 landscape was rebuilt based on it. (3) We have collected 200 boring data of Hanoi. It is analyzing for visualizing of subsurface structures and estimating the order of stratification.
This research results are presented at the international conference (GIS-IDEAS, 9-11th Dec. 2010) .
