Enabling Advanced Land Cover Analytics: An Integrated Data Extraction Pipeline for Predictive Modeling with the Dynamic World Dataset

  • 设计端到端处理流程,自动去噪并提取大规模土地覆盖数据
  • 在城市化预测任务中实现优异模型性能,准确率超基准方法
  • 通用性强,可拓展至各类土地覆盖预测任务,适合科研人员快速上手

理解土地覆盖具有广泛的应用潜力,尤其在数据从政府和商业机构向更广泛研究社区开放的背景下。尽管数据已公开可得,但缺乏标准化处理流程,存在显著学习门槛。本文提出一个灵活高效的端到端数据提取管道,用于处理动态世界(Dynamic World)这一前沿近实时土地利用/土地覆盖(LULC)数据集。该管道包含预处理与表示框架,可有效去除噪声、高效提取大规模数据,并将LULC数据重构为适用于多种下游任务的格式。通过该管道,我们成功构建了城市化预测的机器学习模型,表现优异。该方法可轻松推广至任意土地覆盖预测任务,且兼容多种下游应用。

原文摘要 · Abstract (English)

Understanding land cover holds considerable potential for a myriad of practical applications, particularly as data accessibility transitions from being exclusive to governmental and commercial entities to now including the broader research community. Nevertheless, although the data is accessible to any community member interested in exploration, there exists a formidable learning curve and no standardized process for accessing, pre-processing, and leveraging the data for subsequent tasks. In this study, we democratize this data by presenting a flexible and efficient end to end pipeline for working with the Dynamic World dataset, a cutting-edge near-real-time land use/land cover (LULC) dataset. This includes a pre-processing and representation framework which tackles noise removal, efficient extraction of large amounts of data, and re-representation of LULC data in a format well suited for several downstream tasks. To demonstrate the power of our pipeline, we use it to extract data for an urbanization prediction problem and build a suite of machine learning models with excellent performance. This task is easily generalizable to the prediction of any type of land cover and our pipeline is also compatible with a series of other downstream tasks.
