Map display system, method, and program

The present invention provides a technology for displaying, using simple processing, a scaled view of a narrowly branching intersection in a way that makes the intersection easy to view. A map display system that is for displaying a map on a display unit and is characterized by being provided with a narrowly branching intersection determination means that determines whether a guidance subject intersection is a narrowly branching intersection having a road intersection angle below a prescribed threshold and a scaled view display means that, if the guidance subject intersection is a narrowly branching intersection, displays, on the display means, a scaled view of the guidance subject intersection in which the scale of the guidance subject intersection included in the map is changed so that the rate of the lateral scaling divided by the rate of the vertical scaling is greater than 1. 本发明提供种通过简易的处理，以容易观察窄角分岔路口的比例尺变更图的方式进行显示的技术。该技术构成种在显示部上显示地图的地图显示系统，其特征在于，具有：窄角分岔路口判断单元，判断引导对象路口是否是道路的交叉角小于规定的阈值的窄角分岔路口，比例尺变更图显示单元，在
