Abstract

Kondisi kedalaman perairan yang beragam dan dangkal dapat dilakukan menggunakan teknologi penginderaan jauh (remote sensing) dengan bantuan citra satelit. Tujuan penelitian ini adalah mengkaji algoritma berdasarkan rasio saluran spektral terbaik untuk pemetaan kedalaman perairan dangkal menggunakan citra satelit multispektral Worldview-2, mengkaji akurasi pemetaan kedalaman perairan dangkal berdasarkan analisis citra satelit multispketral Worldview-2 terhadap hasil survei kedalaman serta menganalisis spasial kedalaman perairan dangkal berdasarkan hasil analisis citra satelit multipektral Worldview-2. Penggunaan citra satelit Worldview-2 dimana dengan empat saluran multispektral, yaitu band biru pesisir (costal blue), biru (blue), hijau (green) dan kuning (yellow) dikombinasikan menjadi 8 band rasio yang diintegrasikan dengan data kedalaman hasil lapangan 164 data titik sampel untuk pemodelan kedalaman dan 280 data titik sampel untuk uji akurasi dengan rentang kedalaman 0-24 m. Hasil pemodelan memperlihatkan bahwa model empiris batimetri terbaik yaitu rasio band biru dan band hijau dengan perolehan r yaitu 0.8162. Nilai uji akurasi menggunakan ICC yang diperoleh adalah sebesar 61% dan menggunakan RMSE sebesar 2.42. Penelitian ini memperlihatkan bahwa perolehan uji akurasi bagus dan band rasio biru / hijau mampu menampilkan kedalaman laut di Pulau Parang, Karimunjawa dari 0 m hingga 18 m. Diverse and shallow water depth conditions can be done using remote sensing technology with the help of satellite imagery. The purpose of this study is to examine algorithms based on the best spectral channel ratio for shallow water depth mapping using Worldview-2 multispectral satellite imagery, to study the accuracy of shallow water depth mapping based on analysis of Worldview-2 multispketral satellite imagery against depth survey results and to spatial analysis of shallow water depths based on the results. analysis of Worldview-2 multipectral satellite imagery. The use of Worldview-2 satellite imagery where with four multispectral channels, namely the coastal blue band (costal blue), blue (blue), green (green) and yellow (yellow) combined into 8 band ratios which is integrated with the depth of field data 164 point data samples for depth modeling and 280 sample point data for accuracy testing with a depth range of 0-24 m. The modeling results show that the best empirical bathymetry model is the ratio of the blue band and green band with the acquisition of r is 0.8162. The accuracy test value obtained using the ICC was 61% and using the RMSE was 2.42. This research shows that the results of the accuracy test are good and the blue / green ratio band is able to show the depth of the sea on Parang Island, Karimunjawa from 0 m to 18 m. 
在卫星图像的帮助下,可以使用远程成像技术实现不同浅水的深度。本研究的目的是利用多光谱世界观测卫星图像分析对浅水深度进行最好的光谱分析,根据多光谱世界图像分析分析对浅水深度进行评估,并根据多对焦地球图像分析对浅水深度进行分析。使用卫星图像用四条频道Worldview-2哪里多光谱蓝色乐队(costal蓝色海岸),即蓝黄)、绿色(green)和8(黄色)结合在一起成为乐队现场结果深度集成的数据比例为164点样本进行深度和280建模数据样本来测试准确性和点- 24米的深度范围。建模结果显示,最佳经验测量模型是蓝带和绿带的比例为0.8162。使用ICC获得的精确度测试值为61%,使用RMSE为2.42。这项研究表明,在加勒比海的卡里蒙加瓦岛,进行了良好的准确度测试和蓝/绿比,可以在30到20英尺(0米至18米)的卡里蒙加瓦岛发现海洋深处。发微和低水位的条件可以使用远程感知技术,使用卫星图像的帮助。这个研究之目的是to examine算法改编自《最佳光谱ratio频道用Worldview-2肤浅的水深度绘图卫星多光谱imagery, to study浅薄之评比之水深度绘图改编自分析Worldview-2 multispketral imagery反对深度调查results和卫星的空间分析浅薄之水depths改编自《results。世界观测分析2多光谱卫星图像。Worldview-2 imagery哪里与四多光谱卫星之用channels, namely海岸蓝乐队(costal蓝)、蓝(blue)、绿(green)和黄色(黄色)组合进8 ratios,这是乐队和陆军之深度集成164点数据样本为模特深度和280 point for评比数据样本测试和a - 24米的深度太阳城。再现的广告显示,最优秀的实证主义乐队和绿色乐队的代表是0。计算价值测试使用ICC为61%,使用RMSE为2.42。这项研究表明,准确测试的结果是好的,蓝/绿带可以从10米到18米的卡里穆加瓦岛的海底展示。
