Oceanica’s Perth Coastal Waters Imagery 2008

High resolution (0.5m ground sample distance) ortho-rectified aerial imagery over the Perth Metropolitan coastal waters. The coverage extends from 3km north of Two Rocks to 3km south of Becher Point. The seaward extent is on average 6km, contains the 20m isobath and includes Rottnest Island. Photography capture was undertaken during favourable atmospheric and oceanographic conditions, allowing excellent light penetration through the water column, yielding high quality imagery of benthic habitats in the region.覆盖珀斯都会区近海水域的高分辨率正射校正（ortho-rectified）航空影像，地面采样距离（ground sample distance）为0.5米。其覆盖范围从双岩（Two Rocks）以北3公里延伸至贝彻角（Becher Point）以南3公里；向海延伸平均宽度为6公里，涵盖20米等深线（isobath）区域，且包含罗特内斯特岛（Rottnest Island）。本次影像采集工作在适宜的大气与海洋环境条件下开展，可保障光线良好穿透水体，从而获取该区域底栖生境（benthic habitats）的高质量影像。
