This program plots a path between two points on a map using real map data from the OpenStreeMap project. The path is found by using the A* search algorithm. The project extends the code from a map rendering example in the Github repo for the 2D Graphics Library IO2D in order to display the path.

  • This library must be built in a place where CMake find_package will be able to find it

To compile the project, first, create a build directory and change to that directory:

mkdir build && cd build

From within the build directory, then run cmake and make as follows:

cmake ..
make

The executable will be placed in the build directory. From within build, you can run the project as follows:

./OSM_A_star_search

Or to specify a map file:

./OSM_A_star_search -f ../<your_osm_file.osm>

The map file should be exported from the OpenStreetMap website.

The testing executable is also placed in the build directory. From within build, you can run the unit tests as follows:

./test
