enkeltmerker

Enkeltmerker is a Norwegian term that refers to simple, single symbols used to represent a single feature or point in diagrams, maps, or graphical interfaces. The word combines enkelt (single or simple) and merke (mark), and it is commonly applied across several disciplines to denote a straightforward marker that identifies one item at a time.

In cartography and geographic information systems (GIS), enkeltmerker denote point features such as cities, landmarks, or incidents. Each feature is shown with a single symbol—such as a dot, circle, or other simple shape—whose colour, size, and shape convey category, status, or magnitude. Legends describe the mapping from symbol to meaning, and the markers can be static or interactive to provide additional information through tooltips or popups.

In data visualization, enkeltmerker are used to plot individual observations on charts like scatter plots or time-series dashboards. Consistency in symbol design aids readability, particularly when multiple data layers are present. Markers may be augmented with labels or interactive details to clarify data points without overcrowding the graphic.

Design and accessibility considerations include ensuring sufficient contrast, scalable symbols for different zoom levels, and strategies to mitigate overplotting, such as clustering or data aggregation when many points overlap. While the concept is generic, the specific styling of enkeltmerker is typically guided by the overall visual language of the project or platform.
