5/29/2023 0 Comments Create features arcmap![]() ![]() Because no reference scale is set, the label text size dynamically changes to remain the same at both zoom levels. In the first example, the two map images below show the same map at different zoom levels. ArcGIS Desktop uses reference scales for annotation groups, geodatabase annotation, feature classes, geodatabase dimension feature classes, and data frames. With no reference scale, symbols and labels dynamically adjust to look the same at all map scales. In ArcGIS Desktop, when reference scale is set to a specific scale, and the zoom extent is changed, the text and symbols change scale along with the display (and accordingly, the map). In GIS, Reference Scale is the scale at which symbols and labels appear on a map at their intended, true size.
