Abstract Location-based information plays an important role in many defense applications. OpenStreetMap (OSM) data are very vast and freely available. The information contained in the OSM data cannot be made intelligent without visualizing in a good web mapping interface. The commonly available file format to read the OSM data is .shp or .kml. There are some format converters available but they result in loss of attributes. Hence, the need for the development of an interface which can read and render the OSM data without losing the vital attributes arises. This development effort fulfills this need effectively.

1 Introduction As we all know that today in this twenty-first century almost for everything computer science plays an important role. The role of computer science can be direct or indirect, i.e., in order to make everything more accurate, precise, and fast. We are using computer science, e.g., for calculation calculator was invented, to get the accurate weight of any object many digital weighing machines have evolved, in medical field also every equipment are digitalized from ECG machines to whole body diagnostic machines. Many people are developing expert systems in order make machines more intelligent. This research paper focusses on how are we using computer science for digitalization of maps. V. Kumar (&) V.

Maps are important to visualize the location of a particular area. Maps are being used by peoples around the world from ancient times. In ancient history also we can see that how important is map. Geographic maps of territories have a long tradition and exist from ancient times. In computer science, whole world can be viewed as a large grid of points and each point is denoted by longitude and latitude. If we join some neighbor points then we will get a line data, and if we form a connected line then it forms polygon data. And due to this in computer science a map is formed by combining point, line, and polygon data. There was a time when defense people used to carry paper maps and area models for their military operation. With this older way of rendering the area makes their job tedious and time consuming as to search any location on a paper map waste not only time but also lots of energy. Military operations are never simple operations; they should be quick and accurate. For some operations, they have to spend many days in forests, deserts or hilly areas where anyone can easily lose their location. In sensitive
