DEVELOPMENT OF A GNSS-BASED DATUM NAVIGATION APPLICATION FOR POLITEKNIK KUCHING SARAWAK CAMPUS (D’NAP)

Abstract

The “Datum Navigation Application for PKS” (D’NAP) is developed to address the challenges of locating datum points within the Polytechnic Kuching Sarawak (PKS) campus. Missing or inaccessible datum points would create inefficiencies in surveying and mapping, affecting both students and professionals. This study aims to establish new datum points at strategic locations and integrate them into a digital navigation system. The methodology involves data acquisition using Global Navigation Satellites Systems (GNSS) and Total Station, datum checking, application development, and system testing. The app provides users with essential geospatial information, including bearing, distance, coordinates, and height, improving accuracy in navigation and surveying tasks. This app can also show the direction where the datum position is needed by the user. The results show that D’NAP improves datum navigation in the campus area by reducing errors and delays in survey operations. By leveraging advanced geospatial technology, this application offers a scalable solution that can be expanded to other institutions facing similar challenges. Future improvements may include real-time updates, augmented reality integration, and compatibility with existing GIS systems. Finally, D’NAP facilitates efficient navigation and supports campus operations, ensuring accurate and accessible datum points for users.
