• 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.
For more information, see

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

designated as a

Route Avoid

.

• 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.
