These images have become a vast source of big data and hold immense potential for various applications, including environmental monitoring, urban planning, and disaster management. However, obtaining ground control points (GCPs) and performing geometric correction is a time-consuming and costly process, often limiting the efficient use of these images. To address this challenge, this study introduces a Rational Function Model (RFM)-based rigorous bundle adjustment method to enhance the relative geometric positioning accuracy of multiple KOMPSAT-3A images without the need for GCPs. The proposed method was tested using KOMPSAT-3A images. The results showed a significant improvement in geometric accuracy, with mean positional errors reduced from 30.02 pixels to 2.21 pixels. This enhancement ensured that the corrected images derived from the proposed method were reliable and accurate, making it highly valuable for various geospatial applications.<\/jats:p>","DOI":"10.3390\/rs16162890","type":"journal-article","created":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T07:01:25Z","timestamp":1723100485000},"page":"2890","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Rational-Function-Model-Based Rigorous Bundle Adjustment for Improving the Relative Geometric Positioning Accuracy of Multiple Korea Multi-Purpose Satellite-3A Images"],"prefix":"10.3390","volume":"16","author":[{"given":"Seunghwan","family":"Ban","sequence":"first","affiliation":[{"name":"Department of Geoinformatic Engineering, Inha University, 100 Inharo, Michuhol-gu, Incheon 22212, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4083-7409","authenticated-orcid":false,"given":"Taejung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Geoinformatic Engineering, Inha University, 100 Inharo, Michuhol-gu, Incheon 22212, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,7]]},"reference":[{"key":"ref_1","first-page":"755","article-title":"Study on Disaster Response Strategies Using Multi-Sensors Satellite Imagery","volume":"39","author":"Park","year":"2023","journal-title":"Korean J.
