Ground Control Point (GCP) collection being the most deciding factor for accurate result. The intent of this research is to investigate the optimum number and effect of GCP distribution of map accuracy generated from UAV images. A fixed wing platform with the sensor of digital camera PowerShot SX230 HS is used in the image acquisition process. The images were collected at an altitude of approximately 150 m around UiTM area.

The analysis shows how much the accuracy amends with the increase in the number of GCP and the paramountcy of uniform distribution. The analysis included an examination of the distribution of error based on the distribution of the GCP and reporting of Root Mean Square Error (RMSE). Significance testing of result showed there is significant difference in the RMSE report for the scattered and well distributed GCPs. The RMSE is slightly increase when the GCPs is scattered. From this study it can be concluded that the increasing in the number of GCP the distribution of the GCPs affected the map accuracy generated from UAV images. 2019 Thesis https://ir.uitm.edu.my/id/eprint/63586/ https://ir.uitm.edu.my/id/eprint/63586/1/63586.pdf text en public degree Universiti Teknologi MARA, Perlis Faculty of Architecture, Planning and Surveying
