    Abstract: Methods, systems, and computer program products for polygonal routing are described. A computer system can provide turn-by-turn navigation in a venue for a mobile device using a navigation graph. The navigation graph can include nodes representing a series of navigation areas leading from a start point to an end point in a venue including indoor space. Each navigation area can be a polygon occupying a non-zero geographic area. The computer system updates the turn-by-turn instructions when the mobile device enters or exits a navigation area in the series of navigation areas, until the device reaches the end point.
