Multiscale maps allow you to view geographic data across a range of scales—also known as zoom levels—from buildings to the entire globe. Specifying at what zoom levels content is drawn is known as setting the visible range. Since most data does not need to be shown across all zoom levels, it is a good idea to confirm, and if necessary, change the visible range.
If you are adding data to your map that comes with a predefined visible range, the map will respect that and use that visible range. However, if your data does not have a predefined visible range, or if you want to update the visible range of a layer, you can set this range manually or use Suggest to have Map Viewer automatically calculate the optimal visible range for you. As a result, when you zoom in and out of the map, different layers on the map may turn on and off depending on their suggested visible range. Your map may contain many layers, each with its own visible range. Optionally, you can override these settings and use a different visible range.
Tip:
When a layer is out of range, its name appears in a lighter gray color in the contents and legend than the layers that are in range.
You can determine and change the scale at which a layer in your map is displayed by setting a visibility range on the layer. If you own the layer, you can save the visibility property with the item so the same scale range applies anytime the layer appears in a map.
