System and method for indicating a selected feature of an interactive digital map

A radius parameter may be included with mapping data requests resulting from "longpress" fingertip selection actions on client computing devices including touch screen display interfaces. The radius parameter may be based on the approximate size of a user's finger in pixels. Based on a current zoom level and/or altitude and a latitude, the radius may be used with a finger tip size to determine how far away a location on the screen from the finger tip center is. A remote mapping server may use the radius as a distance limit for performing a snapping action. For example, if the best candidate for a feature snap is outside the range of the longpress radius, then the feature snap may be abandoned, and the remote mapping server returns a dropped pin response to the client. The user may then customize the dropped pin for sharing or other actions.
