Defining Scale Ranges

The first step in creating styles is to define your scale ranges.

Note:

When setting up multiple scale ranges for a layer, make sure that they do not overlap. For example, the ranges 500,000 - 5,000,000 and 2,000,000 - 10,000,000 overlap. In such cases, when the zoom level is within the overlapping scale range, Infrastructure Studio displays the features using the style of the first scale range.

To define scale ranges

1. Open the layer to edit by doing one of the following:
   • Create a new layer.
   • Double-click an existing layer.
   • Click the layer’s tab if the layer is already open.

   For information about creating a new layer, see Creating New Resources. For information about associating a data resource with a new layer, see Specifying the Data Resource for a Layer.

2. In the Style pane of the Layer Editor, in the Scale Ranges area, under From, enter the lower end of the scale range. Under To, enter the upper end of the scale range.

   For example, to make a style visible when the map is zoomed anywhere between 1:250,000 and 1:5,000,000, enter 250000 for From and enter 5000000 for To.

3. To add a new scale range, click Add A Scale Range.
4. Specify From and To values.
5. When working with scale ranges:
   • To copy a scale range, select the range and click Duplicate.
   • To delete a scale range, select the range and click Delete.
   • To change the position of a scale in the list, select the range and click Move Up or Move Down.
6. Click File menu Save.
