Geoskill: Mine Disturbance Monitor

Monitor surface disturbance at mining sites using multi-temporal optical/SAR/DEM data. Detect bare land, pits, dumps, roads, and vegetation removal. Track disturbance objects across years, identify boundary violations, and generate area statistics.

Mine Disturbance Monitor

Monitor surface disturbance at mining sites using multi-temporal optical/SAR/DEM data. Detect bare land, pits, dumps, roads, and vegetation removal. Track disturbance objects across years, identify disturbances outside mine boundaries (compliance concern), and generate area statistics with evidence.

Trigger

Use when the user wants to:

• Monitor mine surface disturbance over multiple years
• Detect bare land / pit / dump / road / vegetation removal expansion
• Identify disturbances outside mine permit boundaries
• Track disturbance object status (new / expanding / stable / reclaimed)
• Generate disturbance area statistics by year and type

CLI Usage

bash

python scripts/mine_disturbance_monitor.py \
  --mine-boundary mine_boundary.geojson \
  --years 2020 2021 2022 2023 \
  --image-dir ./imagery \
  --disturbance-types pit dump road bare \
  --min-area 100 \
  --buffer 500 \
  --output-dir ./disturbance-output

Parameters

Parameter	Required	Default	Description
--mine-boundary	Yes	—	Mine permit boundary (GeoJSON)
--years	Yes	—	List of years to analyze
--image-dir	Yes	—	Directory with per-year imagery (YYYY.tif)
--disturbance-types	No	pit dump road bare	Disturbance types to detect
--compare-dem	No	—	Optional DEM for pit/dump classification
--min-area	No	100	Minimum disturbance area (m²)
--buffer	No	0	Buffer distance around boundary (m)
--output-dir	No	disturbance-output	Output directory
--version	No	—	Show version

Output

File	Description
disturbance_by_year.geojson	All disturbance objects with year, type, area, status
disturbance_type.tif	Raster map of disturbance types
outside_boundary.geojson	Disturbances outside mine boundary (compliance)
summary.xlsx	Area statistics by year and type

Exit Codes

Code	Meaning
0	Success
2	Argument error
3	Dependency missing
6	Validation error
7	Processing failure

数据下载

本 skill 可自动从 Microsoft Planetary Computer 下载数据 (无需 API key):

bash

python mine_disturbance_monitor.py --bbox 116,39,117,40 --date-range 2024-06-01,2024-06-30 --output-dir <tmp>

• --bbox W,S,E,N: WGS-84 边界框 (西, 南, 东, 北)
• --date-range START,END: 日期范围 (YYYY-MM-DD,YYYY-MM-DD)
• --aoi-file <path.geojson>: 替代 --bbox 的 GeoJSON 多边形
• --cache-dir <path>: 缓存目录 (默认 ~/.geoskill_cache)

当用户只给 --bbox + --date-range (没有 --image) 时，skill 自动下载数据。 当用户给 --image 时，走原文件路径 (向后兼容)。
