The Minnesota County Well Index Online HELP
To the right of the map is a frame with a title of LAYERS. This lists the map data that is available for displaying.
The layers have scale-dependent visibility parameters. A layer will be in the layer list, available for displaying based on the scale of the map. For example, the Wells layer is not in the layer list when starting County Well Index Online. The Wells will show up on the layer list and is visible when the map scale is at 1:100,000 or less.
To make a layer visible, make sure that the there is a check in the check box to the left of the layer name under the Visible header. To turn off a layer's visibility, uncheck the visible check box and click the refresh map button. To turn on a layer's visibility, check the visible check box and click the refresh map button. Layers are drawn in order from bottom to top of the layer list. If you make the 2003 Color Air Photos (Zone 15) and the 7.5 Minute quadrangles layers both visible, on your map you will only see the 2003 Color Air Photos (Zone 15) because it overlays (draws on top off) the 7.5 Minute Quadrangle layer.
Note: The Streets layer will show in the layer list at a scale below 1:40,000 but will not display on the map. This is so street labels can be made available at a scale below 1:40,000.
Layer names that are italic and underlined found in the Layer List are links to the Minnesota Department of Health's website with more information regarding that layer. Click to open up a browser to the Web page.
Labeling Map Layers
Labels are available for four layers and are scale-dependent. To label a layer check the Label check box to the right of the Visible check box and click the Refresh Map button. To turn off labels, uncheck the Label check box and click the Refresh Map button.
