In 1986 the Ordenacion de la Cartographia, the law regulating which governs cartographic production was passed. This stamp commemorates the passage of that law. In it cartography is classified into basic cartography, the gathering of actual survey data, the angles and elevations measured in the field. “Derived” cartography, the subject of this design, refers to the use of that data to create a map based on that data, and finally, “thematic” cartography deals with maps with different themes, such as population, land use, boundaries, roads and highways, and so on.
     The map on the stamp, issued in 2006, depicts a derived map of the city of Toledo from the series, Conjuntos Provinciales.
