Abstract: Implementations described and claimed herein provide systems and methods for assessing an exposure value of an asset, such as an out of home advertising asset. In one implementation, location information for an asset at positioned at a location point is obtained. The location information reflects viewing conditions of the asset. Digital elevation model data is obtained for a region in which the location point of the asset is positioned. A viewshed is generated based on the location information and the digital elevation model data. Exposure value information is generated by intersecting the viewshed with transport information.
