Solution description

The wherenow app is a general pathfinding optimality problem solver for arbitrary datasets. Datasets are added as layers with different brightness on top of Google Maps. The app uses A* search internally to calculate the minimum cost going from point A to point B on the map. With sliders the weight of each layer can be adjusted and therefore affect the ultimate solution for the pathfinder. Three different scenarios have been defined: Forest industry, nature treat and training. Each scenario weighs the different used datasets differently and achieves different optimal paths on the map. Some of the used datasets are: roads, ancient monuments, water, soil, bedrock, forests etc.
