Map interface interaction
Techniques for map interface interaction are described. One example method includes receiving user input specifying a map search operation, the map search operation including a first location and a distance determining point each specifying a location in a set of map data representing a physical area; determining a selected distance between the first location and the distance determining point, wherein the selected distance represents a physical distance between the physical locations represented by the first location and the distance determining point; determining a demarcated range based on the first location and the selected distance, the demarcated range representing a subset of the physical area; and displaying one or more target objects in the demarcated range as a search result set, each target object associated with a physical location in the subset of the physical area represented by the demarcated range.
