CDAU (Unified Digital Street Map of Andalusia)

CDAU is the geographic data set of roads and portals in Andalusia, with a topological structure, which allows locating in the territory any geographic object (and its associated variables) that has a postal address, with an approximation at the portal level.The basic entities that are maintained and updated with CDAU are the roads, road sections and portals where the population resides (houses) or where an activity is carried out (establishments or premises), including all population centres and scattered ones. The principles on which the generation and maintenance of this data set is based are those of a single institutional data and decentralised maintenance, in accordance with those that inspired Directive 2007/2/EC of 14 March 2007 (InspirE) and its transposition into domestic law in Law 14/2010, of 5 July, on geographic information infrastructures and services in Spain. CDAU has the status of basic infrastructure of the Statistical and Cartographic System of Andalusia (art. 17.2 of Law 3/2013, of July 24, approving the Statistical and Cartographic Plan of Andalusia (PECA) 2013-2017), and will provide horizontal services to the various public and private agents. As such information infrastructure, the purpose of CDAU is to serve as a cartographic reference base for the management and exploitation of data from both administrative sources and records and from statistical and/or cartographic information.
