A navigation mesh, or navmesh, is an abstract data structure used in artificial intelligence applications to aid agents in pathfinding through complicated spaces. This approach has been known since at least the mid-1980s in robotics , where it has been called a meadow map , [ 1 ] and was popularized in video game AI in 2000.
Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer. Some software presented here is free, but maps may need to be paid ...
A navigation bar (or navigation system) is a section of a graphical user interface intended to aid visitors in accessing information. Navigation bars are implemented in operating systems, file browsers , [ 1 ] web browsers , apps, web sites and other similar user interfaces .

OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS ) and relate them to edges in an existing street graph (network), usually in a sorted ...
Before path planning, the map is discretized into a grid. The vector information is converted into a 2D array and stored in memory. The potential field path planning algorithm determines the direction of the robot for each cell. This direction field is shown overlaid on the robotic map containing the robot and the obstacles. The question for ...
