WaterTrace: catchment-scale water risk analysis

WaterTrace在开放源代码的基础上提供权威和普遍可访问的流域规模数据。WaterTrace是一个平台，每月发布当地集水区按水源（地表水、地下水）和按用途（农业、工业、市政）分列的供水变化的历史估计和未来预测。WaterTrace的开发目标是策划一个透明和可信的“单一真相来源”，它结合了地球观测和来自每个集水区的现场数据。它受益于最近的创新，这些创新创建了全球范围内的高分辨率土地覆盖数据集，可通过开放许可证近实时提供。

WaterTrace delivers authoritative and universally accessible catchment-scale data on an open source basis. WaterTrace is a platform that publishes both historic estimates and future projections of the change in water supply by source (surface water, ground water), and water demand by use (agriculture, industry, municipal) for local catchments, on a monthly basis. Developed with the objective of curating a transparent and trusted 'single source of truth', WaterTrace uses a combination of earth observation and in-situ data from each catchment analysed. It benefits from recent innovation that has created high-resolution datasets of land cover at global scale, available via open license in near-real time.
