Abstract

Spatial databases are essential tools for preserving potential marine genetic resources. Banda Island, the study area fir this project, is rich with marine biodiversity that can easily be exploited. A spatial database was designed for Banda Island I order to locate existing selected marine species among its rich coral reefs.

Two LANDSAT-7 ETM satellite images of the study area were processed to apply the Bottom Feature Index and perform ISO class unsupervised classification. The images were then mosaicked to create a classified image showing the entire archipelago of Banda Island. The result was a raster image with classified features deviating relatively less from actual measurements of area in Banda Island.

A vector data of the study area was created from a topographic map and was used to create a geographic information system (GIS). The GIS was capable of helping users locate existing coral, algae and seagrass species on Banda Island’s coral reefs and specifying area measurements. Using a software extension, the Banda Islands GIS was made available through local network. A web site was also created containing pertinent information on the marine ecosystem, socio-economic, climatic conditions and geography of Banda Island.
