Abstract
<p> This study describes the improvement of the image analysis of network camera using the orthomosaic created from UAV-SfM/MVS survey and the morphological characteristics of Shichiri-Mihama Ida beach based on the estimated shoreline positions extracted by a network camera and DEM obtained by UAV-SfM/MVS survey. The estimated shoreline extracted from the network camera image denotes the position in the range of 1~2 m above sea level by comparison with the DEM so that it was located on the land side from the actual shoreline. The application of the network camera including UAV-SfM/MVS survey makes it possible to identify the waves that caused the beach deformation between observations.</p>
