10. APPLICATION OF GIS FOR ASSESSING ADAPTATION OF ECOLOGICAL SCENERY TO SERVE PRIORITY SPATIAL ORIENTATION FOR CASSAVA DEVELOPMENT AT KON TUM PROVINCE

Tóm tắt

Geographic Information System (GIS) has been becoming a useful application in the assessment and management of many fields. This paper studies on integrating the average multiplication method and application of GIS for assessing the ecological adaptation of cassava to scenery factors. The methodology of this study is divided into two steps that are defining the scenery features as well as building the criterions assessment, and establishing a thematic database for building zoning map of scenery, then the average multiplication is integrated to assess the ecological adaptation of cassava.
