Eliminace vlivu chybných hlášení uživatelů na kvalitu navigační databáze

Abstract

This thesis approaches the issue of updating the database for in-car navigation devices with the help of users themselves. The introduction describes the general problem of navigation data, user communities and their links in the updating process, while also focusing on current options for reporting errors in the maps. Subsequently, a selected sample of the data used for this work consisting of reports from the users themselves is being analyzed. Following part of the thesis deals with methods of analysis of those data while suggesting options on how to process information from users with an emphasis on maintaining the quality of the database. The proposed procedures are then tested, their limitations outlined and evaluated, and finally the possibilities of further increase in the efficiency of the process of updating the database with the help of users are presented. Use of this work is to be primarily in specialized companies that are updating their database utilizing their users' feedback.
