WorldView-2 8 band imagery of the SE corner of Negros Oriental, central Philippines

The dataset contains 100km^2 of WorldView-2 multispectral (8 bands, 2m resolution) and panchromatic (0.5 m resolution) imagery of the south east coastline of Negros Oriental, in the central Philippines, from Dumaguete to Bonbonon. The imagery was georeferenced, orthorectified, and pan-sharpened by the commercial imagery provider (GeoImage), and was delivered as 2 panels.

The imagery was collected for the purpose of identifying key types of submerged coastal habitats in the region, in particular coral reefs and seagrass beds.

The uploaded dataset also contains a subset of the 100km^2 image. The 2 panels of imagery delivered by GeoImage were atmospherically corrected using dark-object subtraction, then mosaicked together. The final imagery was trimmed to exclude terrestrial areas and optically deep water.

The imagery was later classified into habitat types using a Maximum Likelihood approach and extracted for manipulation as polygon shapefiles in spatial analysis software.

本数据集涵盖菲律宾中部东内格罗斯省（Negros Oriental）东南部海岸线（杜马盖地至邦博农）范围内100平方千米的WorldView-2多光谱（8个波段，分辨率2米）与全色（分辨率0.5米）影像。商业影像提供商GeoImage已对该影像完成地理配准（georeferenced）、正射校正（orthorectified）与全色锐化（pan-sharpened）处理，并以2幅分幅的形式交付。

本次影像采集的核心目标为识别该区域的典型近海海岸生境类型，重点聚焦珊瑚礁与海草床。

本次上传的数据集还包含该100平方千米影像的子集。GeoImage交付的2幅分幅影像已通过暗物体减法（dark-object subtraction）完成大气校正，随后被拼接为一幅完整影像。最终成品影像经裁切处理，剔除了陆地区域与光学深水区域。

后续研究人员采用最大似然法（Maximum Likelihood）将该影像按生境类型完成分类，并提取为可在空间分析软件中操作的多边形形状文件（polygon shapefiles）。
