Australian Reflectance Grid 25 (ARG25)

The Australian Reflectance Grid (ARG) is a new generation Earth Observation product suite from Geoscience Australia. These standard data products deliver optical surface reflectance data across the Australian landmass and its coastal fringes. This means the products are representative of the optical reflectance properties of the surface, with the variable effects of the atmosphere removed. The resulting datasets are effectively sensor agnostic and future products in this suite are intended to be readily comparable between scales. The first product in this suite is the ARG25, a medium resolution (25 m) grid based on Landsat imagery.

澳大利亚反射率网格（Australian Reflectance Grid，ARG）是澳大利亚地质科学局（Geoscience Australia）推出的新一代地球观测产品套件。该系列标准数据产品可提供澳大利亚陆域及沿海岸带的光学地表反射率数据。此类产品能够表征地表的光学反射特性，且已剔除大气带来的各类可变影响。所得数据集在传感器层面具备通用性，该套件后续推出的产品旨在实现不同尺度间的便捷可比。该套件的首款产品为ARG25，这是一款基于陆地卫星（Landsat）影像构建的中等分辨率（25米）网格产品。
