Topo USA User Guide
You can
view two types of data at the same time
using the split-window function and by
connecting
the data with the Data Locations option in the Map Files tab.
The only data types that you can view in the right map window are DeLorme Topo North
America data and 3-D TopoQuads data. To view 3-D TopoQuads data in the right map
window, you must
disable your DeLorme Topo North America data connection
and enable
only the 3-D TopoQuads data connection.
The dataset that displays in the left map window is dependent on the selection made in the
data drop-down list at the top of the left map window.
