Abstract

UAVs with RTK technology offer high-accuracy aerial mapping, with RTK Radio and RTK NTRIP as two correction methods affecting orthomosaic precision. While previous studies compared these methods in terrestrial surveys, their impact on UAV-based orthomosaics remains underexplored. This research evaluates and compares the accuracy of UAV-derived orthomosaics using RTK Radio and RTK NTRIP to provide practical guidance for optimal mapping applications. This research combined UAV RTK photogrammetry and GIS to produce high-precision aerial maps in two areas of Padang City with different topographies. Data were collected using DJI Mavic 3 Enterprise RTK with RTK Radio and RTK NTRIP techniques, supported by GCPs, BMs, and satellite imagery, then processed into orthomosaics for analysis. Accuracy was assessed using ICPs and statistical measures like RMSE to compare the spatial precision of both correction methods under varying terrain conditions. The results show a difference in mapping accuracy between RTK Radio and RTK NTRIP aerial photographs, with RTK Radio achieving 0.683 accuracy and 0.450 RMSE, while RTK NTRIP reached 0.563 accuracy and 0.371 RMSE. RTK Radio is more suitable for areas lacking CORS access but still requires GCP verification. RTK NTRIP performs better in urban areas with strong CORS networks. Combining both methods with adequate GCPs provides an effective solution for mapping in varied or densely vegetated terrains.

Abstract

This study aims to analyze the coverage of TransPadang bus stops in relation to educational facilities in Kuranji District, Padang City. The method used is spatial analysis based on Geographic Information System (GIS) with a buffer technique of 500 meters from the location of TransPadang bus stops. The data analyzed included the distribution of TransPadang bus stops, bus routes, and formal educational facilities such as elementary schools, junior high schools, high schools, and universities, which had been validated through field surveys. The results of the analysis show that TransPadang bus stops tend to be spread along main road corridors, while educational facilities have a diverse distribution pattern. Some educational facilities are within the service range of bus stops and are categorized as served, while others are outside the range and are not yet directly served. The results of this study indicate that the TransPadang public transportation service to educational facilities in Kuranji District is not yet evenly distributed and still requires service network development.

Abstract

This study aims to analyze and map land use distribution within the Air Tawar Campus of Universitas Negeri Padang (UNP) using Geographic Information Systems (GIS). Effective campus spatial management requires accurate and up-to-date spatial information to support academic activities and future development planning. The data used in this study include satellite imagery, campus boundary maps, and official supporting data such as building and facility records, land data, and road and bridge records as of December 31, 2022. The research methodology consists of data collection, georeferencing, land use digitization, field verification (ground check), and spatial analysis of land use area and proportions using QGIS software. The results indicate that built-up areas dominate the campus land use, covering approximately 60% of the total area, followed by open spaces and green open spaces at 31%, road networks at 7%, and river bodies at 2%. These findings highlight the importance of balanced land use planning to ensure sustainable campus development while maintaining environmental quality.
