Global Positioning System (GPS) technology proposals an accurate and efficient method to measure and record topographic data, exclusively slope data needed for various practices. The use of GPS allows faster and more accurate data collection, even in difficult areas, as well as allowing the integration of real-time data into digital mapping systems. A 3D model of a slope is a digital representation of an inclined surface in three dimensions, commonly used in engineering, architecture, geography, and gaming. It accurately depicts variations in elevation, gradient, and terrain features, making it useful for various applications. The main objectives of this research are to display 3D models of several areas in UiTM Seri Iskandar and to calculate the volume of each model. The research is conducted through topographic data collection by using GPS with integrated MyRTKnet technique which comprises the measurement of slope coordinate points with GPS devices to obtain accurate elevation and slope angle data. Additionally, used the software tools to generate models from the collected data, which involves GIS based software or specialized 3D modeling tools known for terrain and volumetric modeling. As well as calculated the volume by comparing plane heights above and below specific elevation levels, identifying changes in terrain displacement and landform structure. It is expected to contribute significantly in providing valuable insights to geotechnical analysis, urban planning and environmental management by understanding slope stability is crucial for preventing landslides, optimizing construction projects, and ensuring sustainable land use. Lastly, with determined the volume differences between reference heights, the study provides understandings into terrain differences, elevation changes, and surface crinkles.
