Valhalla is an open source routing engine and accompanying libraries for use with Open Street Map data. The demos repository serves as a sort of scratch pad which can be used to test and demo different pieces of the valhalla organization working together to accomplish their various tasks.
Each demo, if needed, will provide its own instructions on building and testing.
For detailed information about what types of things are contained within the demos repository, please see the more detailed documentation.
You are free to use any of the demos for your own projects. The demos, and all of the projects under the Valhalla organization use the MIT License.
We welcome contributions to the demos. If you would like to report an issue, or even better fix an existing one, please use the demos issue tracker on GitHub.
If you would like to make an improvement to the code, please be aware that all valhalla projects are written mostly in C++11, in the K&R (1TBS variant) with two spaces as indentation. We generally follow this c++ style guide. We welcome contributions as pull requests to the repository and highly recommend that your pull request include a test to validate the addition/change of functionality.
