Military logistics is a process of planning and carrying out the movement and maintenance of military forces. Therefore, fuel delivery for military vehicles has an important place in military logistics and it must be handled in most efficient way. Today, fuel delivery systems are planned with the use of different type of maps and software applications. While vector maps, which are most widely used maps, contains features like coordinates, major road networks, railroad networks and international boundaries, they do contain the knowledge of height of a point. However, military vehicles are capable moving on not only human made roads, but also different types of terrains. As a result, while calculating shortest distance and shortest trip time for fuel delivery purposes, the topographic map, maps showing height of a particular area, must be used. Moreover, the vehicles capabilities such as moving on different terrain types, moving on a slope and fuel amount should be considered. Although there are many applications offering shortest path finding solution in the market, there is no such a platform, which satisfies all the needs of users mentioned above. Thus, in this project these issues will be addressed.

     Patika Application will be an application that run in Android Platforms to find a shortest path between multiple points on a map which is visualized using height maps. Applicaion will be used for military logistic fuel-carry purposes.
