PENERAPAN MODEL DATA UAV FOTOGRAMETRI UNTUK SISTEM INFORMASI GEOGRAFIS ZONA PEMANFAATAN LAHAN (Studi Kasus: Kampung Bukide Kecamatan Nusa Tabukan)
Abstract
Penelitian ini menghubungkan data remot sensing Unmaned Aerial Vehicle (UAV) untuk pengolahan data spasial berbasis sistem informasi geografis. Teknologi ini merupakan salah satu alternatif solusi untuk mendapatkan data lebih detil, real time, cepat dan lebih murah dibandingkan dengan penggunaan peta citra satelit. Kelebihan lain dari AUV dibandingkan foto citra satelit, AUV dalam proses pengambilan data foto udara berada pada posisi di bawah awan sehingga mampu menghasilkan data foto udara beresolusi tinggi. Hal tersebut dipengaruh oleh karena AUV tidak banyak di intervensi oleh perubahan atmotfer dibandingkan dengan foto hasil citra satelit. Proses digitalisasi menggunakan metode pengenalan objek dan segmentasi citra mengunakan perangkat lunak agissoft metashape, ArGIS10.4 dan Geomatica versi 2014. Hasil dari tahapan metode tersebut diketahui wilayah kampung bukide memiliki luas ± 143,59 ha. Luas tersebut diklasifikasikan menjadi tiga bagian yaitu tutupan lahan vegetasi 135,49 ha, area pantai 1,55 ha dan Pemukiman seluas 6,59 ha. Hasil ini diperoleh dari pengenalan citra data UAV serta pengambilan titik koordinat pada 6 bentang alam yang digunakan sebagai acuan pada proses pengenalan citra dan georefensi.
This study links remote sensing data to Unmaned Aerial Vehicle (UAV) for spatial data processing based on geographic information systems. This technology is an alternative solution to get more detailed, real time, fast and cheaper data compared to using satellite imagery maps. Another advantage of AUV compared to satellite imagery is that in the process of capturing aerial photo data, it is located under the cloud so that it can produce high-resolution aerial photo data. This was influenced by the fact that the AUV was not much intervened by changes in the atmosphere compared to satellite images. The digitization process uses object recognition and image segmentation methods using the 2014 version of Agissoft Metashape software, ArGIS10.4 and Geomatica. The results of these stages of the method show that the area of the Bukide village has an area of ± 143.59 ha. The area is classified into three parts, namely vegetation land cover of 135.49 ha, beach area of 1.55 ha and settlements of 6.59 ha. These results were obtained from the introduction of UAV data images and the taking of coordinate points in 6 landscapes which were used as references in the image recognition and georeference process.
