Evaluation of land suitability for sugarcan eproduction using spatial information model
developed by GIS has been regarded as highly effective method which could be adopted to provide
the required information compared with conventional operation. The method not only minimizes
the factors introduced into the analysis but also provides the steps reliable outcome through clear
cut step of operation which could be updated. The output obtained could be used to back up
decision-making on sugarcane production at provincial level. Apart from this, this method could
also be adopted to examine land suitability of certain target area s. For Udon Thani province, it was
indicated from the result of this study that the area classified as high suitability, Moderate suitability
and Marginal suitability occupied 0.85%, 17.87% and 19.12% of the provincial area respectively.
