SignalTrack User's Guide
Use this dialog to select the data you want to use to build the
layers of your map. Select the type of data you wish to add from
the left window and then select the data in the main window.
After you have built up the layers press the Save Map button on the mapping tool bar.
MANIPULATING LAYERS
Once you've loaded a map, individual layers can be disabled and enabled. The Layers drop down
menu lists all the layers in the order in which they are displayed. The topmost layer is the first layer
in the list; the next layer is listed second, etc. A check box next to the layer name indicates that the
layer is enabled and being displayed. Many times layers above other layers obscure layers below
them. So, to see the lower layers you must disable the layers above the lower layers. Merely
enabling (checking) a layer may not display that layer if the layer above it obscures it.
Layer can be removed by selecting the Remove Layer menu item from the Layers drop down
menu. When the dialog is displayed, check the layers you wish to remove and press OK.
