The optimization research on map marker coverage

The development of computer's application changes our daily life. Online maps application and popularization provide us a more convenience life. As individual users, we usually search for single or several map markers on the Internet. For the existing online map, whether from the positioning accuracy, reaction speed, and operating convenience aspects, it is an advanced system. But for the abundant makers, due to the positions of the searched makers are so close, there is a problem of overlapping coverage between markers and markers at a certain zoom level, which requires the maker clustering algorithm to optimize the geographic information display. Through the aided optimize of interaction design in the process of maker clustering, it can help us to enhance the study of geographic data mining and analysis.
