The GRP methodology: An approach to build routes based on points of interest

Many research areas are developing applications that use the Global Positioning System (GPS) in order to improve human's life. In routing systems most of the studies are focused on time improvements. Despite they notify users the instructions that they should follow in their travels, they do not include support features that could be useful as landmarks or points of interest (POIs). In this paper, the Routing with Points of Interest (GRP) methodology is proposed. It is based on an application ontology that is used to describe POIs as shops, hospitals and schools, among others, located on the roadways of a case study. The GRP gives the users instructions to go from one place to another, combining semantic geospatial analysis tools, web and mobile technologies. The routes begin in the mobile position and after applying a geospatial process; the user obtains a map with the route, POIs located on the route, and instructions to change the direction with visual references to help him on his trip. The GRP methodology provides a filter to let user select the kind of business that he wants to visualize, besides the route elements. The cartography used on this work allows the map visualization without an Internet connection.
