geoskill-precision-forestry-monitoring

该 Skill 以 Python 命令行脚本实现精准林业遥感监测:由 DSM−DTM 生成 CHM,用局部峰值检测提取单木位置与树高,由冠幅反演胸径并借异速生长方程估算单木与林分蓄积量;统计郁闭度,用 NDVI/NDRE 做健康分级,由 SAR 后向散射反演地上生物量,输出 GeoTIFF、GeoJSON 与 JSON 统计及经营建议,默认本地离线运行,也支持合成数据模式。

CHM tree height and crown width allometric volume, NDVI/NDRE health grading and SAR biomass fusion for precision forestry

精准林业遥感监测 | Precision Forestry Monitoring

Integrates multi-source remote sensing for stand-scale precision forestry monitoring, covering four levels — individual tree, stand, health and biomass — to support forest resource inventory, carbon sink estimation and management decisions.

Tree height / individual trees: CHM = DSM − DTM, with local peak detection (non-maximum suppression) extracting individual tree locations and heights. Crown width is used to invert diameter at breast height (DBH = k·CW), and the allometric equation V = a·DBH^b·H^c estimates individual-tree volume, which is summed into stand volume. Canopy closure is the proportion of canopy pixels whose CHM exceeds a threshold (∈[0,1]). Health is graded by a combination of NDVI and NDRE (healthy / moderate / stressed). Biomass is estimated from SAR backscatter σ⁰ (dB) → linear → power-function empirical relationships, and management recommendations are generated from canopy closure / stand volume / health.

Dependencies / 依赖

pip install 'numpy' 'rasterio' 'scipy' 'scikit-learn'

Usage / 使用方法

Basic usage

python geoskill-precision-forestry-monitoring.py --bbox 116.0 39.0 117.0 40.0 [other options]

Example 1 (synthetic stand, offline)

python geoskill-precision-forestry-monitoring.py --bbox 116 39 117 40 --synthetic --output-dir ./out

Example 2 (real 6-band imagery (DSM/DTM/Red/NIR/RedEdge/SAR))

python geoskill-precision-forestry-monitoring.py --input forest.tif --output-dir ./out

Example 3 (health grading using NDVI only)

python geoskill-precision-forestry-monitoring.py --input forest.tif --health-method ndvi --output-dir ./out

Example 4 (increase the minimum detection height and window)

python geoskill-precision-forestry-monitoring.py --input forest.tif --min-height 5 --footprint 7 --output-dir ./out

Example 5 (adjust the canopy closure threshold)

python geoskill-precision-forestry-monitoring.py --input forest.tif --closure-threshold 3 --output-dir ./out

Output / 输出

File Format Description
chm.tif GeoTIFF Canopy height model (tree height, m)
health_grade.tif GeoTIFF Health grade (3 healthy / 2 moderate / 1 stressed / 0 bare ground)
biomass_t_ha.tif GeoTIFF SAR-derived above-ground biomass (t/ha)
canopy_mask.tif GeoTIFF Canopy cover mask
trees.geojson GeoJSON Individual tree locations (height / crown width / DBH / volume)
forestry_report.json JSON Stand statistics + management recommendations
output-manifest.json JSON Run manifest

Data Source / 数据源 / Source

Multi-band GeoTIFF with band order DSM / DTM / Red / NIR / RedEdge / SAR. Alternatively, use --synthetic to generate physically consistent simulated data (fully offline).

Privacy / 隐私声明 / Privacy

  • Runs offline by default; --synthetic mode requires no network at all.
  • All processing is performed locally; user data is never uploaded.

精准林业遥感监测 | Precision Forestry Monitoring

融合多源遥感实现林分尺度精准林业监测,覆盖“单木—林分—健康—生物量”四个层次,支撑森林资源调查、碳汇估算与经营决策。

树高/单木:CHM = DSM − DTM,局部峰值检测(非极大值抑制)提取单木位置与树高;由冠幅反演胸径 (DBH = k·CW),再用异速生长方程 V = a·DBH^b·H^c 估单木蓄积量并累加为林分蓄积量。郁闭度取 CHM 高于阈值的冠层像元占比(∈[0,1])。健康由 NDVI 与 NDRE 组合分级(健康/中等/胁迫)。生物量由 SAR 后向散射 σ⁰(dB)→线性→幂函数经验关系估算,并据郁闭度/蓄积量/健康生成经营建议。

pip install 'numpy' 'rasterio' 'scipy' 'scikit-learn'
