面向生物多样性的对地观测

Satellites observe forests, wetlands, coasts and the ocean surface repeatedly and across borders, which field surveys cannot. Earth observation maps ecosystem extent, change and some aspects of condition, and it gives a consistent record for places where no one monitors on the ground.

02申请

What earth observation and remote sensing does here.

Earth observation and remote sensing gather information about the Earth’s surface and atmosphere from airborne and spaceborne sensors. They provide consistent, repeatable measurements over areas that are hard to monitor on the ground. In biodiversity and nature, climate and hazards and oceans and coasts, earth observation maps exposure, damage and environmental change across borders and sectors. It supports rapid assessment after disasters and long-term monitoring of risk drivers. The canonical description is on STEM Commons.

Forest loss and disturbance alerts

Landsat, Sentinel-2 and Sentinel-1 time series are classified to map annual loss and near-real-time disturbance, with radar used where cloud blocks optical sensors.

Wetland and mangrove dynamics

Radar and optical time series track flooding regimes, wetland extent and mangrove change, separating seasonal variation from conversion.

Vegetation structure and condition

Spaceborne lidar and radar estimate canopy height and biomass, and spectral indices track phenology and stress as proxies for ecosystem condition.

结果如何核查。

Products are assessed against ground reference data using accuracy matrices and independent samples. Cross-calibration between sensors checks consistency over time.

核查如何开展
Accuracy assessment with area estimationMaps are scored against a probability sample of reference points, and areas are adjusted for classification error
Cross-sensor consistencyTrends are checked across sensors and processing versions before they are reported
Field calibrationStructure and condition proxies are calibrated against inventory plots
Coverage reportingCloud, revisit gaps and missing scenes are reported as no data, not as no change

Clouds, revisit gaps and mixed pixels limit what can be observed. Changes in sensors and processing can create artificial trends.

Earth observation for biodiversity: Earth observation processing chain

Processing levels are mission specific; Sentinel-2 runs from Level-0 raw data to Level-2A, and CEOS Analysis Ready Data sets the minimum for analysis.

  1. 01 Ground segment

    1. 01获取来源Sensors acquire optical or radar data. For Sentinel-2 the Level-0 product is raw image data in Instrument Source Packet format.
    2. 03Level-1 radiometric and geometric processing步骤Level-1B gives calibrated top-of-atmosphere radiance. Level-1C adds geometric corrections, including orthorectification, for reflectance.
  2. 02 Pre-processing

    1. 04Level-2 atmospheric correction步骤Level-2A applies an atmospheric correction to the Level-1C orthoimage. Its main output is a surface reflectance product.
    2. 05Scene classification and masks步骤Level-2A includes scene classification, and Level-1C also makes cloud, cirrus and snow or ice masks. Quality flags travel with the product.
    3. 06可直接用于分析的数据数据集CEOS Analysis Ready Data meet minimum processing requirements and are organised for immediate analysis and interoperability.
  3. 03 Analytics

    1. 02Reference data数据集Field samples or other independent reference data are used to check the product.
    2. 07Change analysis建模Classification and time-series methods detect change in the analysis-ready data. The method is chosen by the analyst.
