The purpose of the thesis is to improving visualization capabilities of the Sen2Cube.at web application for visualizing image with considering advanced cartographic methods and User-Centered approach. The research begins by understanding current condition of Sen2Cube.at system through user evaluation, internal discussion, and SWOT analysis. Then, formulating Sen2Cube.at visualization capabilities thresholds concept and transforms it into practical guidelines and image map models. The last part of this thesis focusing on developing User-Centered geovisualization tools that needed by the current users particularly in terms of inferring the semantic enrichment image maps. There are two visualization tools that proposed through UI prototype. Both theorical concept and practical result of this thesis might be a basic concept for further development of visualization tool in Sen2Cube.at web application.
