![]() We use the latest Rich Internet Application (RIA) technologies from Microsoft to implement the proposed methods for our search portal – GeoSearch. To address these problems, we propose a visualization- and interaction-enhanced discovery workflow. Existing approaches have visualization problems that impact the efficiency of geospatial resource discovery including (1) search portals lack intuitive and diverse information visualization methods to present search results (2) functions to sort, filter, explore and analyse search results are inadequate and inefficient and (3) value-added information to help users make selection is missing. ![]() Well-designed graphical user interfaces improve user experience and also help convey important information to assist decision-making. Information visualization and user interaction play critical roles in geospatial resource discovery processes.
