Abstract - Developments in information technology, especially information systems have brought convenience that promises a work efficiency. For example geographic information system is a tool with a computer system that is used to map conditions and events that occur on the face of the earth is a system that is helpful in providing and presenting information needed by users. The development especially in the aspect of environmental needs in order to overcome or reduce the impact of disasters in the Sumatran region, and by improving the performance of the BPBD, it is necessary to have a GIS-based information system that can show BPBD disaster points that already exist in North Sumatra. With the existence of map information, especially in the web system, it is expected to provide fast and accurate information, especially knowing the exact location of the disaster. thus facilitating the work of officers in providing disaster information at the head office. Keywords - Geographic Information Systems, Mapping, Web.

<p>Generally, satellite images contain very significant information about geographical features such as rivers, roads, building and bridges etc of the earth. Geographic Information System (GIS) requires these features for automatic detection and it has been corrupted by various types of noise. Curvelet Transform (CT) is used in the proposed system for denoising the images. Advantages of multi resolution image such as line, compatibility of human visual system and edge detection are provided. Then K-Means clustering is used in this system for segmentation purpose after the pre processing done.</p><p>First, K-Means algorithm is used for segmenting background and water then extraction of bridges is done based on pixel intensity difference.   </p>
