        <gco:CharacterString>
          The Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) offers a simple and efficient
          way to access and transform geospatial data from a variety of federal data archives. AppEEARS enables users
          to subset geospatial datasets using spatial, temporal, and band/layer parameters. Two types of sample
          requests are available: point samples for geographic coordinates and area samples for spatial areas via
          vector polygons. Sample requests submitted to AρρEEARS provide users not only with data values, but also
          associated quality data values. Interactive visualizations with summary statistics are provided for each
          sample within the application, which allow users to preview and interact with their samples before
          downloading their data.
