An approach is provided for computation of risk index. The approach, for example, involves acquiring historical probe data associated with an area. The historical probe data comprises data associated with distribution of vehicles entering or leaving the area in a given time partition. The approach further involves obtaining map feature data associated with an entrance or exit of the area, from a geographical database. The map feature data comprises data associated with physical objects in vicinity of the area. The approach further involves computing a risk index for the entrance or the exit for the given time partition, based on the historical probe data and the map feature data. The risk index indicates a probability of occurrence of a hazard in the vicinity of the entrance or the exit. The approach further involves storing the risk index as an attribute of the entrance or the exit in the geographic database.

Solar panels may have manufacturing defects that warrant a recall by solar panel manufacturers. Given the large quantity of solar panels in a solar farm, it is challenging to identify and track those panels affected by the recall. The present invention describes system and method embodiments for solar panel tracking for the convenience of solar panel service or replacement. Panel identifiers of solar panels in a solar table installed on an installation site of a solar farm are scanned such that the panel identifiers of the solar panels may be associated with the geographical information at the installation site. A geographical database for solar panels may be created and updated, with each panel having an entry of panel information and geographical information. When a recall is issued, involved solar panels in the solar farm may be quickly and accurately identified using the geographical database.

An approach is provided for lane-level direction-of-travel detection from overhead imagery. The approach, for instance, involves processing overhead imagery data of a road network to determine a plurality of features indicative of a direction of travel of at least one road lane of the road network. Each feature of the plurality of features indicates a candidate direction of travel. The approach also involves determining the direction of travel of the at least one road lane based on a weighted voting mechanism applied based on the candidate direction of travel of each feature. The weighted voting mechanism weighs the candidate direction of travel of each feature based on a feature type of each feature. The approach further involves associating the determined direction of travel as an attribute of the at least one road lane in a geographic database.
