Abstract
A process and system allow for visually representing style layer properties of a digital map across various zoom levels. From a style sheet for a digital map, a plurality of style layer properties for a style layer corresponding to the digital map are determined for rendering in the form of a visual map, including various property values for different zoom levels. From these, a zoom level function is generated between pairs of the values for a particular style layer property, by assigning property values (a continuous range or finite set) between the first property value and the second property value in the pair. A visual map based on vector map tiles rendered according to the zoom level function is displayed according to the selected zoom level. As values are changed, the visual map is updated to reflect the changes.
