发明名称 System and method for ranking geographic features using viewshed analysis
摘要 Systems and methods for ranking geographic features in a geographic information system are provided. In particular, geographic features can be assigned ranking scores based on characteristics of viewsheds associated with the geographic features. In particular, characteristics of a viewshed associated with a geographic feature can be analyzed to assess the visibility of the geographic feature. A ranking score can be assigned to the geographic feature based on the characteristics of the viewshed. The ranking score can be used prioritize information in a geographic information system.

主权项 1. A computer-implemented method for determining ranking data for geographic features, comprising: selecting, by one or more computing devices, a geographic feature associated with a geographic area; determining, by the one or more computing devices, a viewshed associated with the geographic feature; evaluating, by the one or more computing devices, one or more characteristics of the viewshed associated with the geographic feature; generating, by the one or more computing devices, a ranking score for the geographic feature based at least in part on the one or more characteristics of the viewshed associated with the geographic feature; and storing, by the one or more computing devices the ranking score for the geographic feature in a memory; wherein determining, by the one or more computing devices, a viewshed associated with the geographic feature comprises: accessing, by the one or more computing devices, a three dimensional model associated with the geographic area;identifying, by the one or more computing devices, a plurality of geographic points within the geographic area;determining, by the one or more computing devices, whether greater than a predefined threshold of a three dimensional representation of the geographic feature in the three dimensional model is visible from each of the plurality of geographic points; andselecting, by the one or more computing devices, the geographic point for inclusion in the viewshed associated with the geographic feature if greater than the predefined threshold of the three dimensional representation of the geographic feature is visible from the geographic point.
