GIS MODELING DURING MAKING IMPORTANT DECISIONS USING SPATIAL ANALYSIS

Abstract

The article substantiates the importance of GIS modeling to facilitate the workflow and for more effective decision-making, as well as analyzes the geospatial data to solve some problems when using ArcGIS software. Nowadays, GIS technologies are used in many spheres of life-support and are improved work efficiency. The processes of globalization in the modern world encourage to quality and effective management of various spheres of our lives. This is especially the case as regards the introduction of computer technology, as well as the global Internet.

The importance of GIS modeling is substantiated in order to facilitate the workflow and increase the effectivity of important decisions. Researches and publications on GIS and their implementation are considered, also examples of successful problem solving and project implementation using GIS analysis are given. Using network analysis (graph theory), modeling of some common problems and their solutions was performed, on the example of the road network of the city of Kyiv.

The solution of common problems related to the road network was studied, as a result of which were identified the nearest hospitals to the places of accident, were found solutions to the routing problem and were selected service points from the list for abbreviations. The considered experience of using geographic information systems together with conducting own research confirms the opinion that in the modern world which is full of challenges, GIS is a highly technological effective tool for analyzing of large amounts of geographic information and making difficult decisions.
