Definition(en): Files which form part of an ArcInfo Coverage, which is a data model whose purpose is to store georelational data such as spatial location and descriptive data. Each ArcInfo Coverage resides in an ArcInfo workspace, a directory which contains two or more folders. These packages are generated using ArcGIS software, produced by Esri (https://www.esri.com/en-us/arcgis/about-arcgis/overview.) Files with the .txt extension contain text strings describing a geographic feature, formatted in user defined tables.
