Abstract
The role of Geographic Information Systems (GIS) in mapping and viewing current conditions as well as alternative handling of flood problems in Medan City and its surroundings. By integrating geographic data and spatial analysis in regional planning, it is hoped that the role of GIS can help in making better decisions in various sectors, including flood prevention, environment, transportation and housing in Medan City.The aim of this research is to analyze the potential for flooding in the city of Medan and its surroundings using the QGIS (Quantum Geographic System) software application, which is expected to be able to map flood areas with spatial analysis results so as to minimize the impact of the risk of flooding that will occur. The relevant map data needed to analyze potential flooding is; Medan city map, rainfall conditions, topography and land use.The targets are flood-prone areas or areas which often become unresolved problems, starting from the many complaints from the public to the impacts that result in material and physical losses, disruption of activities and transportation activities as well as the social impacts they cause. With this research, it is hoped that it can become an alternative and solution in minimizing and dealing with flooding problems that often occur in the city of Medan and its surroundings.
