Analysis of shallow water benthic using of SPOT-6 imagery data on Miang Besar Island, Kutai Timur, Indonesia

Abstract

Potential observation of coastal waters habitat by an extensive coverage difficult reached by in-situ observation methods, so that using image data is expected to study of data in a short time and broad scope. SPOT-6 satellite multispectral imagery as imagery data was used in this study to interpret habitat conditions spatially. Research was conducted on Miang Besar Island, East Kutai by imagery data processing and field survey. Field surveys in shallow waters to observe the appearance of coral objects, seagrass, and mangroves. Imagery data processing stages by radiometric and geometric correction and transformation of lyzenga algorithm by supervised classification methods. The classification results in 3 community schemes namely; coral, seagrass and mangrove on coastal of Miang Besar island showed a presentation of mangrove communities distribution area 29.000 m2 and percentage cover 54% by Rhizopora apiculata, Seagrass community distribution area 8,900 m2 and percentage cover 76% by Enhalus acorides, and coral community distribution area 5,800 m2 and percentage cover 62% by Hard coral.
