Overview
This classified layer maps mangrove extent, open mudflat and canopy condition across a set of tropical estuaries. It is intended to support habitat comparison and restoration planning.
Classes are kept separate so users can inspect change without reducing habitat condition to a single score.
Method
Multispectral scenes are combined with field checks and segmented into habitat classes. The archive retains the observation year and a confidence value for each cell.
Field guide
| Field | Description |
|---|---|
class_code |
Habitat class assigned to the cell. |
canopy_index |
Relative canopy condition index. |
observation_year |
Year of the source observation. |
confidence |
Classification confidence. |
Known limitations
Cloud cover, seasonal inundation and mixed pixels can obscure narrow or fragmented habitat. Use the confidence layer when interpreting small patches.
概览
这份分类图层绘制了多个热带河口中的红树林范围、开阔泥滩和冠层状况,面向生境比较和修复规划。
各类别被分开保存,方便用户检查变化,而不是将生境状况压缩成单一评分。
方法
多光谱影像与野外核查数据结合后,被分割为不同生境类别。档案为每个网格保留观测年份和置信度值。
字段指南
| 字段 | 描述 |
|---|---|
class_code |
分配给网格的生境类别。 |
canopy_index |
相对冠层状况指数。 |
observation_year |
源观测的年份。 |
confidence |
分类置信度。 |
已知局限
云层、季节性淹水和混合像元可能遮挡狭窄或破碎的生境。解读小斑块时,请结合置信度图层。
