CARTOGRAPHIC SYMBOLS AND THEIR USE

Аннотация

Cartographic symbols constitute the visual vocabulary through which maps communicate spatial ideas. Their design choices—shape, size, colour, texture, orientation and animation—encode complex attributes and relationships in a form that can be rapidly perceived and interpreted by users. Advances in digital cartography, web mapping and data‐visualisation theory have revitalised interest in the semiotic power of symbols, yet inconsistent standards and the proliferation of ad-hoc icon sets threaten both legibility and interoperability. This article synthesises the principles of symbolisation drawn from classical and contemporary cartographic literature, evaluates the cognitive implications of symbol design, and reports the findings of an empirical study that measured user performance across alternative symbol systems in a web-mapping environment.
