WaterTrace: catchment-scale water risk analysis

WaterTrace在开源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来源（地表水、地下水）供水和按用途（农业、工业、市政）供水需求变化的历史估计和未来预测。WaterTrace的开发目标是建立一个透明和可信的“单一真相来源”，它结合了地球观测和分析每个流域的现场数据。它受益于最近的一项创新，即创建了全球范围内的高分辨率土地覆盖数据集，这些数据集可以通过开放许可近乎实时地获得。

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.
