• What is a project?
You can save all of your work as a single workspace so you can open it again later.
These saved workspaces are called projects.
A project is made up of the following items: coordinates of the map center, current
zoom level, current magnification, map display preferences, any added items: such
as draw layers, routes, and so on. As you create new routes or draw layers, change
preferences or the map center, and so on, they are added to the current project. You
can save or discard changes.
To learn how to create a project, see
Creating and Deleting Projects
• What is the difference between a stop and a via?
When routing in DeLorme Topo North America, you have the option of
adding/inserting stops or vias
in the route. A stop is a location in a route where you
want to stop and then proceed from. A via is a location on the map that you want the
route to use.
For example, if you create a route between Portland, Maine, and Yarmouth, Maine,
with no stops or vias, the route directions will tell you to take I-295. However, if you
want to take US Route 1 instead, you can place vias in the route on US Route 1 to
force the route to go by way of US Route 1. If you plan on stopping in Falmouth
Foreside for lunch, you will want your route directions to reflect that stop. When you
add a stop, you can recalculate to include it.
This map shows the area between Portland, Maine, and Yarmouth, Maine, with two
vias and one stop.
• What's the difference between adding and inserting a stop or via?
The Insert Stop/Via function arranges stops/vias geographically in the route.
The Add Stop/Via function adds stops/vias in the order you add them to the route.

Adding and Inserting Stops and Vias
• Why did my route fail to calculate?
Your route will fail to calculate if you create a route:
• With a route start, stop, via, or finish point in an area that you have
• That includes route points outside the United States. If you have the North
American version of DeLorme Topo North America, for routes that include
points outside of the United States, Canada, or Mexico.
• On an island without roads. In this case, DeLorme Topo North America looks
for the nearest road to that island to place the route point. If the nearest road
is not routable (for example, it is the only road on the island and/or the island
does not have ferry access), you will get an error message saying, "Route
failed to calculate."
• Why do X marks sometimes display on the map when I calculate a route?
• When you place a route point in a location that isn't on a street, DeLorme
Topo North America finds the closest street to that location, marks the space
between the point you clicked and the street with X marks, and starts the
route at the street.
