Scale range

One of advantages of digital map versus paper ones is their displaying flexibility. You can display and print digital maps in different scales, using different map legends and so on. However, when using zoomed in map legend symbols or the image is compressed when scaling, some objects can cover another ones which causes problems in visual map perception. There is a technology called Map generalization to make your digital map nice-looking and more informative. One of the main generalization rules is to set visibility of every object depending on current scale of displaying map. Scale range can be set for class of objects (forest, lake, sidewalk, etc) when digital classifier is creating, it also can be redefined for any single object by digital map editor tools. Besides user-defined scale range Panorama provides automatic generalization procedure for different object categories. Starting at some scale relative to the basic one, Panorama changes size of labels, removes relatively small objects, changes thickness of polygon boundaries etc.
