Landmark

Landmark is a term that originated in the aviation and shipping. He describes a situated Küstenseezeichen (eg a lighthouse ) or another flashy, usually highly visible topographic object. Accordingly, for example, churches, towers, windmills, castles, mountains or detached distinctive large trees can represent landmarks. Such landmarks play an important role in spatial orientation and terrestrial navigation. Therefore, they are optionally labeled on maps by special map sign.

Landmark, however, characterize an area without having to be necessarily significantly in the topographical sense of need. However sights, which rise above a town or across the country, such as the Cologne Cathedral, the Eiffel Tower, the Hercules in Kassel- Wilhelm height, the Burj al Arab Hotel or natural monuments like Mount Uluru are as landmarks frequently landmark become, so here the concepts may overlap.

Numerous landmarks are in the Ruhr area with its highly visible spoil heaps and disused shaft towers. They were redesigned as industrial monuments in part by artists. For example, installed on the top of the Essen Schurenbachhalde the 14.5 meter high sculpture Slab for the Ruhr Richard Serra. The towering sculptures Rhine Orange by Lutz Fritsch and location center are landmarks that want to make a character deliberately special places and their history or on relations between places carefully.

In the context of image registration landmarks denote successive salient points within images (eg corners, cross points, noticeable structures) that can be found manually or automatically, and a mapping multiple images or permit to a model (see also the control point ).
