Abstract: Architecture having an algorithm that computes visible structures for a user within a distance defined by one or more environmental conditions. An environmental condition such as reduced visibility due to a weather condition such as rain, fog, etc., can be used to define a radius about the user in which possible points of interest (POIs) can be identified as viewable based on current weather visibility data. The altitude of the user is considered when identifying the possible POIs. The user is more likely capable of viewing other structures as POIs when the user is at a higher altitude. If the user is known to be standing on a ridge overlooking a city, this information can be processed by the algorithm to then show more POIs relative to this elevated user location than if the user was at approximately zero altitude. A sight map is generated based on these considerations.
