The Land Suitability Evaluation for Samut Prakan Province in Thailand for Eco Industry Development by Applying the Geographic Information System

Abstract

The purpose of this study is to present the Geographic Information System (GIS) that supports land suitability evaluation for the development of target land in Bang Pu Sub-District Municipality in Samut Prakan Province in Thailand in order to promote the concept of the eco-industrial town. GIS was applied as the research methodology. SIEVE analysis was employed to evaluate suitable land. There are four factors involved in evaluating the land in this study. The first factor is the industrial density factor. The second factor is the industrial cluster factor. The third factor is the accessibility to green and recreation areas factor. The last factor is the risk to the urban ecology and environment factor. Each factor has three score levels in descending order: 3, 2, and 1. It was found that suitable target land could be found in five locations. There were 408 industrial factories on the target land (68.92% of 592 Group 3 factories). The findings are important information for the Samut Prakan Provincial Office to select suitable land, to make strategic and master plans, and to manage resources in order to maximize efficiency and develop the province into a model eco-industrial town in accordance with the province's vision.
