摘要:Generally, investigation for protection of the wildlife is difficult because it takes much work and time, and frequent monitoring. Therefore, studies of monitoring with remote sensing and GIS were carried out for solving such a problem. In this study, a habitat of an ecosystem was estimated by remote sensing and GIS in Iriomote Island. The objective creatures were an Iriomote cat and a coral reef. The habitat estimate for an Iriomote cat was carried out with HSI, the values of which ere showed in all areas of Iriomote Island. Next, the coral reef mapping for its cover evaluation was made with a depth correction algorithm. This result coincided with the sighting points of the Iriomote cat for two years. As a result, the habitat areas of the Iriomote cat were showed mostly on the edge outside the island. Also, the habitat areas of the Iriomote cat did not coincide with the National Park areas. Moreover, the estimate of the number of Iriomote cats would be carried out with HSI. Especially, the classification with ALOS would be carried out more exactly than JERS-1 and ASTER, because of ALOS with higher resolution and higher transmissivity to the seawater. In the above, the ecosystem evaluation of the land and sea was carried out in a short time and with low cost by GIS and a satellite image. Remote sensing was considered valuable for monitoring of an ecosystem. This study would be contributed for monitoring and protection of Iriomote Island ecosystem
