The Area Sample feature in the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) is now operational with the release of Version 2.0. The Area Sampler enables users to subset one or more geographic areas (polygons) temporally, and by layer, as well as mosaic, reformat and reproject the data in one simple step. In addition to returning area-specific raw data values, AppEEARS also returns quality data with definitions. Interactive graphs and plots are available within the interface to explore trends in the data before download. The Area Sample functionality complements the existing operational ability to request Point Samples using geographic coordinates. Access AppEEARS here.
AρρEEARS offers users a simple and efficient way to perform data access and transformation processes by enabling users to download only the data they need. AρρEEARS provides access to a wide range of environmental variables derived from sources such as Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) data as well as population variables from the Gridded Population of the World (GPW) Version 4 collection.
