Vector shapefiles of the rural-urban interface in Portugal estimated for different periods (1990, 2000, 2006, 2012)

<p>Vector shapefiles of the rural-urban interface (RUI) in Portugal estimated for different periods&nbsp;(1990, 2000, 2006, 2012).&nbsp;RUI&nbsp;was mapped considering the first and the second level hierarchy of CORINE Land Cover (CLC). A specific geospatial approach was designed to extract the area of intersection between a buffer around the artificial surfaces and the area resulting from the sum of the forest and semi natural areas plus the heterogeneous agricultural areas. We adopted a buffer width of 1 km, corresponding to two times the spatial resolution of CLC inventories.&nbsp;</p> <p>The field &ldquo;code_yy&rdquo; refers to CLC class level 3.
