THE DEVELOPMENT OF GEOGRAPHIC INFORMATION SYSTEM SHOWING WATER QUALITY MONITORING RESULTS IN THE AREA OF MUANG KAEN PATTANA MUNICIPALITY, MAE TAENG DISTRICT, CHIANG MAI PROVINCE

Abstract

The objectives of this research are: 1) to study on water quality of water sources in the area of Muang Kaen Pattana Municipality, Chiang Mai Province, 2) to develop Geographic Information System showing Water Quality Monitoring Results in the community, and 3) to evaluate the results of the use of Geographic Information System. The sample group used in this research consisted of 5 experts who provided information on the development of Geographic Information System. These samples were obtained by using purposive sampling. Besides, there were also 30 samples of the experimental group obtained by using simple random sampling. Research tools were interview form, Efficiency Assessment Form, and Questionnaire on Satisfaction. The operation was tested by using Black Box Testing and White Box Testing. Data were analyzed using mean and Standard Deviation.     

      The results revealed that: 1) Quality of surface water from 7 locations of sample collection was classified as Type 3 standard with the right level of temperature, turbidity, pH, and dissolved oxygen in overall picture, and 2) Developed Geographic Information System for Water Quality Monitoring would be able to display the locations of sample collection on the map and present the results of water quality in table and graph formats. Consequently, users were able to search for and access information on water quality report of local water sources conveniently. The results of evaluation on efficiency of the system conducted by the experts were in high level ( = 4.55) and the results of evaluation on satisfaction of users were also in high level ( = 3.92).
