localiser

Localiser is a term with several related meanings across languages and technical fields. In French, the verb localiser means to locate or localize. In English usage, localizer is the more common form, but localiser can appear in bilingual documents or as the name of a specific component in some contexts.

In localization and translation work, a localizer can refer to a person or a software component that adapts products for a target locale. This includes translating text, adjusting date and number formats, currencies, graphics, and culturally appropriate content. Localization is the broader process that combines translation with internationalization, engineering, and quality assurance to make software, documentation, and media usable in different regions.

In medical imaging, a localiser (often called a localizer) is a preliminary image or sequence used to identify anatomy and plan subsequent acquisitions. Examples include scout views in magnetic resonance imaging and computed tomography, which help position slices and reduce repeats.

In aviation, the Localizer is a specific function of an Instrument Landing System (ILS). It provides horizontal guidance, transmitting signals that align an aircraft with the runway centerline during approaches and landings.

Beyond these fields, the term can denote general devices or methods intended to locate a position or object. The common thread is the attribution of location, be it linguistic, anatomical, navigational, or computational. See also localization, localizer in aviation, and MRI localizer sequences for context.
