Database engine for selecting object e.g. mountain, has selection module that selects object in cartographic database according to calculated distance separating geographical position of determined oriented line passing through position

摘要

The engine (10) has a determination module (16) determining an oriented line passing through a given geographical position. A selection module (18) selects objects in a cartographic database (12) according to a calculated distance separating geographical position of the determined line, where the object is visible across a lens of a camera. The module (18) selects a single object, from the selected objects, near the position. Independent claims are also included for the following: (A) a system for identifying a visible view across a lens comprises a database engine (B) a method for selecting an object in a cartographic database (C) a computer program comprising instructions for executing an object selection method (D) an information storing medium comprises of instructions for executing an object selection method (E) a method for identifying a visible view through a lens.
