A method of analyzing credibility based on LOD control of digital maps

ABSTRACT

Digital maps are widely used and appear on all types of platforms for integrating content. Users can change display region and scale by panning, zooming in, and zooming out on a digital map. Level of detail (LOD) control for a given region at a given scale is decided by the designer of the digital map. Therefore, rules for displaying objects have limited credibility. For example, it is possible that equivalent objects do not display consistency, or nonequivalent objects do display consistency, even if users believe equivalent objects are displayed consistently. We propose a method to calculate the display validness on LOD-controlled regions and scales for increasing the credibility of digital maps. In particular, our method determines the equivalence of objects based on the display pattern at each scale and the size of the region determined to be the object's territory. In addition, we calculated the display validness using the equivalence of objects. In this paper, we describe our prototype system.
