DEVELOPMENT OF A WEB-BASED SYSTEM FOR GNSS DATA TRACKING AND APPLYING CORRECTIONS IN GIS ENVIRONMENT

Ilieva, T.
Abstract:
The subject of this study is the development of a web-based system for real time data tracking and applying GNSS corrections in GIS environment. This includes the data structures specification in a geospatial database, obtaining a methodology for system realization and discussing the results with an accent to the accuracy of the corrected GNSS positions. The system for tracking and applying GNSS corrections in GIS environment is entirely built by using free and open source software and has web-based interface. There are three web pages - the first for login information and system description, the second contains a map, where the results in real time are shown on the third page is for reports and history of tracking. The system uses data directly from GNSS receivers in NMEA protocol, stored in PostgreSQL/PostGIS database and accessed via php code. The data is corrected in the database and published with Geoserver by using OGC Web Services. For the user interface HTML, CSS and JavaScript are used. In this research is presented an example, which proves that the tracking and calculating of GNSS corrections in order more accurate positions to be obtained is possible by using web-based GIS.
