Visualization of Geographic Information Retrieval Results Supporting User Participation

As the swift development of 3S (remote sensing, geography information system and global positioning system) technology and relevant information technologies, the demand for Geographic Information Retrieval has risen sharply. Based on user-centered principle and the problems in traditional geographic information retrieval results visualization, an improved scatter coordinate system was proposed. Firstly, the mapping relationship between the spatial entities and the coordinate point was established. Combining the spatial attributes and non-spatial attributes, the retrieval results were expressed graphically. Meanwhile, necessary interactive methods were provided to help users cognize and evaluate the results conveniently. Consequently, the objectives could be obtained more efficiently. Issues to be further studied and improved were discussed in the end.
