Use of Geographical Information Systems for Thailand

Abstract

Geographical Information Systems (GIS) are systems for capturing, storing, manipulating, analyzing and displaying data with geo-reference. GIS are comprised at least three different components: an information system on geospatial information and data, set of georeferenced or geospatial data, and a management component capable of analyzing und checking the data. This management component can be used to gain new insights into the data set and for the assessment and forecast of situations and scenarios related to geospatial data. Although GIS have been presented for decades serving different functions in many areas, their use for problems in Thailand has recently increased considerably. Typical domains, in which GIS is used, are the planning of transport and services, urban and environmental management, and the visualization of health and economic data. As Geographical Information Systems provide easy access to a variety of detailed geospatial objects, the problem of naming and retrieving them correctly remains important. These variations of names can lead to confusion about the correct name of a place, building, or other geospatial object as well as to poor or even incorrect search results in stand-alone, networked or Web based GIS. In this paper, the authors present a review of past and current GIS projects related to Thailand, with major application domains, and results reported. Furthermore, the paper shows some future work that will lead to a solution of the above mentioned problem.
