Monitoring Near-shore and Insular Marine Protected Area Network using Landsat, ASTER and IKONOS Images

Md. Zakir Hossain, Nitin K. Tripathi


Designing and establishment of Marine Protected Area Network are found common in many countries. While MPA Network design is growing, the measurement of landscape as well as seascape stability and its implications for protection and conservation of coastal resources are needed to be emphasized. The application of remote sensing and GIS in designing and monitoring marine protected areas is highly recommended in many studies. And now with the advent of high resolution satellite images the monitoring tasks are extended from top of the hill to down in the sea. In this paper, merits of some moderate to high resolution satellite images in mapping and monitoring terrestrial and benthic habitats are analysed. The study presents results on assessing spatial and temporal changes in and adjacent to the MPA Systems in a study site in Thailand. The methods employed include interpretation and analysis of satellite images with several spatial resolutions (30m, 15m, 4m) and GIS datalayers. Spectral Analysis and Principal Component Analysis (PCA) were applied initially and the outputs were compared. Image classification with water column correction techniques and several GIS methods were used extensively for mapping, monitoring and assessment tasks. Monitoring and assessment were done separately for land and sea areas. While the quantitative analysis was made for the terrestrial part, for benthic habitats only the qualitative comparison was made on outputs obtained from different satellite images. Finally the study has proposed a monitoring protocol for near-shore and insular MPA Network.
