Most of the methods for landslide susceptibility assessment are based on mathematical relationships established between factors responsible triggering phenomenon, named conditioning factors. These usually derived from geographic data commonly handled through Geographical Information System (GIS) technology. According to adopted methodology, after an initial phase conducted GIS platform, need be...

Today, incorrect use of lands and land use changes, excessive grazing, no suitable using of agricultural farms, plowing on steep slopes, road construct, building construct, mine excavation etc have been caused increasing of soil erosion and sediment yield. For erosion and sediment estimation one can use statistical and empirical methods. This needs to identify land unit map and the map of effec...

Environmental impact assessment is an important tool in assuring that development projects will go according to environmental limits. The need for a systematic method of evaluating the environmental effects of a project or a plan has been recognized for several decades. In this study application of improved mathematical matrices for environmental impact assessment was suggested. For this, quali...

Important and complex spatial decisions, such as allocating land to development or conservationoriented goals, require information and tools to aid in understanding the inherent tradeoffs. They also require mechanisms for incorporating and documenting the value judgements of interest groups and decision makers. Multiple-criteria decision analysis (MCDA) is a family of techniques that aid decisi...

This study aimed to analyse and evaluate the land suitability for certain fruit trees in Thuy Bang commune using GIS techniques in combination with a multi-criteria approach. At first, the databases for GIS analyses had to be developed. The data were obtained through scientific literature review, expert opinions, interviews, and professional officers. The suitability assessment in the studied a...
