Abstract:
This paper presents a system for creating a travel diary that shows a list of the locations visited on a trip with durations as well as a travel trace on a map. It also describes the implementation methods for the system. Proposed system determines the visited locations and infers the names of the sites and managed places with boundaries such as fences and roads, including the locations, from a GPS trace using an area-based reverse geocoder (ARG) newly developed for the system. Because it infers the names of sites using a site-boundary database, the ARG is more precise than conventional reverse geocoders, particularly when multiple sites are close to a portion of the travel trace. Proposed system introduces a sequence matching method that simultaneously matches consecutive GPS points with a boundary provided by the ARG. Because it uses site boundaries to find a sequence of noisy GPS points across the boundaries, the method effectively reduces the impact caused by GPS noise.
