Research and Optimize Geocoding with the User's Coordinates on VMap

Abstract

In this article, we present an optimal method for searching the address on VMap based on the current location and the entire view of the users. The article will focus on understanding and researching factors to optimize user's search, enhancing the user’s experience on VMap. The article used data from OpenStreetMap, open source of Pelias geocoder to run test suites. Specifically, based on comparison results with the best rated digital map platform today, Google Maps, we calculated the effectiveness of the method. The proposed method helps to diversify search results with the user's current location, providing relevant search results in case the user's view does not have much influence on search optimization (such as user's view too large or too small). From there, as the optimal basis for searching of many other locations other than the user's current location and view, location bias priority will be enhanced. Besides, evaluation methods need to be performed on multiple users to evaluate effectiveness. This method was applied for VMap and showed optimistic results.
