Utilization of Aerial Photograph for Spasial Data Using Quadcopter (Ijo Temple Complex, District Prambanan, Yogyakarta)

摘要

Ijo temple complex is included in a complex of protected cultural heritage. Documentation of cultural heritage is not only limited to photo archives, relics of historical objects, but also present spatial data. The spatial data of aerial photographs on a large scale is important to get information in detail. Currently, the development of science and technology on the utilization of UAV (Unmanned Aerial Vehicle) is growing rapidly, one of the use of aerial photographs for cultural heritage. The aircraft used is a type of rotary wing quadcopter because it is more stable than fixing wing and narrow study area. Excess use of aerial photography to obtain spatial data that is more efficient job execution time, can reach small areas in a short time, and they cost less. The purpose of this study to determine the level of utilization of the acquisition of aerial photographs using quadcopter as presenters of spatial data. The method in this research that Bundle Block Adjustment to process aerial photography into a mosaic image with the principle patch aerial photographs through point cloud. Shooting is done by using quadcopter with a flying height of 45 meters. Planning to fly that will produce good spatial data. Shooting is done vertically. Orthophoto imagery maps generated can be presented on a scale of 1: 1,400 which can provide detailed information Ijo temple complex region. 1.64 cm spatial resolution. Map of the resulting image has a 99.73% accuracy rate horizontal and vertical accuracy rate of 98.62%. Based on the degree of accuracy that the processing of aerial photographs can have a high rate of data acquisition.
