| Summary: | Volume measurement is an important part of construction and mining work, including coastal volume to monitor changes occur along the beach. The volume measurement is usually done using conventional methods. The LiDAR method is the advanced mapping technology used for volume measurement purposes. However, it does involve high costs. Low-cost technology such as the UAV SfM-MVS (Unmanned Aerial Vehicle Structure from Motion Multi-View Stereo) found to be useful for the purpose of measuring the volume. The UAV photogrammetry technology make the mapping can be done all over area including the beach area. However, does the variation of UAV altitude beach mapping comes out with different volume measurement? This paper discovers the volume measurement for UAV photogrammetry mapping at 10m, 20m, 30m, 40m, and 50m altitudes along linear form of Desaru beach area in Johor, Malaysia. The research shows that, GSD of UAV mapping does not influence the UAV volume measurement, the uncertainty trend of UAV volume measurement happen when variation of UAV altitude mapping is done. Large error in UAV mapping effect the UAV volume measure. On the other hand, accurate mapping at certain UAV altitude is not a condition for quality UAV volume mapping as the UAV altitude mapping influence the result. |
