Abstract

Spatial archives in the form of analog maps still encountered in several work units, however, as times progressed, the quality of these maps decreased in terms of the materials used which could affect their accuracy. There are several techniques used in converting from analog to digital maps, including scanning technique, and a unification coordinate system with the rectification method. This study aimed to find out the horizontal accuracy and the accuracy class of rectified maps. The data used was an analog map of a map of the boundary demarcation of the Konak Forest area, Rejang Lebong Regency scale 1:1000. The analog map was produced more than 30 years ago. The steps carried out in this study were preparing data from scanning analog maps, setting coordinate systems, input GCP, control rectification, calculating RMSE and CE values, analyzing, digitizing, layout. The result of the rectification map shows the use of 4GCP produces the best value with RMSE 0.14m and CE90 0,20 and the horizontal accuracy is class 1 on a scale of 1:1000. 6GCP produces RMSE 0.5m and CE90 0.75 and the horizontal accuracy is class 3 on a scale of 1:2500. 10GCP produces RMSE 0.6m and CE90 0.95 and the horizontal accuracy is class 3 on a scale of 1:2500.

Abstract

Jalan merupakan infrastruktur yang penting dalam menunjang kemajuan suatu wilayah. Survey kondisi jalan merupakan salah satu aspek kegiatan dalam pemeliharaan jalan tujuannya agar jalan dapat terpelihara dan terawasi. Kegiatan survey kondisi jalan dapat memanfaatkan teknologi fotogrametri menggunakan wahana tanpa awak dengan kamera non metrik karena dapat menyediakan data detail/situasi jalan dan cukup efektif dalam menunjang pekerjaan survey kondisi jalan. Detail/situasi jalan dapat diidentifikasi berdasarkan orthophoto yang dihasilkan melalui pengolahan data foto dari kegiatan pemotretan udara. Penelitian ini bertujuan untuk mengetahui ketelitian geometri orthophoto. Data yang digunakan dalam pengujian menggunakan hasil pengolahan foto udara berupa orthophoto. Metode yang digunakan dalam menguji akurasi geometrik orthophoto merujuk pada Peraturan Kepala Badan Informasi Geospasial No 8 tahun 2018. Hasil uji akurasi geometri horizontal (CE90) sebesar 0,018 (RMSE 0,012) dan vertikal (LE90) sebesar 0,026m (RMSE 0,016). Sehingga dinyatakan orthophoto ini memiliki ketelitian horizontal sebesar 0,018meter dan ketelitian vertikal sebesar 0,026m. Kelas ketelitian horizontal orthophoto adalah kelas 1 dan kelas ketelitian vertikal orthophoto ini adalah kelas 1.
