Development of track log and point of interest management system using Free and Open Source Software

Recent advanced performance of low-cost Global Positioning System (GPS) and GPS-enabled cell phones has contributed a great deal to the development of location-aware services and systems. High-speed broadband technology has promoted collaborative projects such as OpenStreetMap or other User Generated Contents services. In this research, a Web-based prototype system for GPS track log and point of interest (POI) management was developed to archive a collaborative framework in field surveys. The main function of the system can be separated into three parts: data collection, data management, and data quality enhancement. The system supports real-time data collection for the future ubiquitous environment and also can monitor real-time GPS positions. This research shows functionalities that can minimize GPS errors using Dilution of Precision filtering and data quality enhancing techniques using the Douglas-Peucker algorithm and PgRouting. The research introduces a system that provides an interoperable framework in which to work with other geospatial services through open geospatial standards.
