Vol.6, No.4 (2010), 21-28168665762-s2.0-84857775907https://repository.li.mahidol.ac.th/handle/123456789/29043This paper is the implementation of a Geographic Information System (GIS) that can assist in planning patrol activities or route mopping within forests. Uthai Tham's Husi Kha Khaeng wildlife sanctuary was selected as the case study. AH principles and data used were acquired from the National Park, Wildlife and Plant Conservation Department. The Routing Decision Support System (RDSS) is a GSS application implemented for the analysis of the prest patrol routing. RDSS was implemented using visual studio 2905 and ArcGIS Engine 9.2. This article provides a patrol route creation concept which is appropriate for patrol routing in the forest and as a system for patrol routing. The route creation concept applied GPS patrol data and Topographic maps for making the most suitable patrol route. RDSS is capable of supporting the executive to make decisions in planning, managing and choosing patrol routes to increase the efficiency of patrol routing. © Geoinformatics International.Mahidol UniversityEarth and Planetary SciencesArticleSCOPUS
