# Via-Points and NoGo-Areas
|
|
|
|
BRouter can process via-points and nogo-areas, and [brouter-web](/brouter-web)
|
|
offers on online interface to edit both of them.
|
|
|
|
Nogo areas are useful if you encouter an obstacle that is not contained in the
|
|
underlying map. But they can also be useful in planning alternative routes by
|
|
excluding e.g. a certain bridge or ferry.
|
|
|
|
For offline use, nogo-areas can be defined as wayoints using a special [naming convention](../users/android_advanced.md#using-nogo-areas).
|
|
Handling of via-points during offline use depends on the mode of operation, see
|
|
the README for details.
