Scale Sensitive Treatment of Features in a Geographic Information System

摘要

Systems and methods for presenting information in response to a user interaction with a geographic image at a point of query in a geographic information system are provided. A user can request information at point of query in the geographic image. Responsive to the user request, the geographic information system can search for and obtain information associated with the request. As part of the logic used to return information responsive to a request at a point of query, a zone of influence can be defined for one or more features depicted in the image. The zone of influence can be defined by a pixel threshold in a pixel space associated with the geographic image. The pixel threshold can be constant across a plurality of zoom levels of the geographic image.

1. A computer-implemented method of presenting information in conjunction with a point of query, comprising:
receiving, by one or more computing devices, a request for information at a point of query, the point of query associated with a geographic location; responsive to the request, obtaining, by the one or more computing devices, information associated with a feature located proximate to the point of query, the feature having a zone of influence encompassing the point of query, the zone of influence defining a region in a geographic image depicting the feature; and providing for the display, by the one or more computing devices, the information associated with the feature in the user interface; wherein the zone of influence of the feature is defined by a pixel threshold in a pixel space associated with the geographic image, the pixel threshold being defined irrespective of the scale of the geographic image.
