Recent Research Interest: Usefulness of GIS and RS in Urbanization Studies in developing countries
By the accelerating urbanization, Asia and Africa face serious social problems including overpopulation, urban explosion, segregation, poverty and health damages, and the increase of natural disasters such as floods, air & water pollution, landslide, tsunami, etc. In this connection, it is important for geographers to scientifically examine what has been happening on the surface of the earth. However, we are bound to say that urbanization studies are challenging in Asia and Africa, because of the lack of geospatial data over the countries, including maps, statistics, and administrative documents.
There is much less geospatial information in developing countries in comparison with the western world. For example, Censuses provide a valuable source of data that enables scientific analysis, but the question items and year of a census conducted vary by country, and there are many countries that have not conducted a census for more than ten years. The statistical units vary by country, and only a few countries have available local statistics and digital maps displaying boundary zones.
Under these circumstances, satellite images have become a comprehensive data source for empirical studies among Asian and African countries. Recently, high-resolution imagery from satellites such as Landsat, Sentinel-2, Suomi NPP, ALOS and MODIS became available for free or at minimal cost, and technologies such as geographic information systems (GIS) and remote sensing (RS) can now be used to facilitate highly precise temporal and spatial analysis of horizontal and vertical urbanization.
Today, advance in geospatial technologies is remarkable in the processing of large amounts of spatial data. In Asia, the number of geographical studies involving complex system sciences (machine learning), such as genetic algorithms (GA), cellular automata (CA), and multi-agent systems (MAS) is significantly growing. On top of the processes from the past to put forward, inductive thinking as a way for prediction is becoming a valid feature. The use of state-of-the-art simulation techniques and scenario analyses is not only limited to spatial forecasting but also can be introduced to the fields of spatial governing and spatial control/management.
Geographers have made possible achievements in the research of spatial processes, and from here on, armed with geospatial technologies, they are expected to actively commit in regional policy and planning in rapidly growing Asia and Africa.
