CDAU (Unified Digital Street Map of Andalusia)
About this good practice
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.
Resources needed
Development of technological platform and other jobs contracted to companies in the sector: 2.285.746,57€ and, since 2011, the project has an average staff of 8 technicians
Evidence of success
Integrated into the regional emergency management system, and in the public schooling online tool for choosing schools. It is used as a basis to georeference people and companies and generate geostatistical products that are disseminated through the IECA website, and also to improve accessibility to acute stroke care. Tool for local councils addressing house street number issues in areas of scattered population distribution, for tourist guides APPs.
Potential for learning or transfer
The CDAU project is relevant as it aligns with Interreg goals of improving public services and fostering economic growth. Its impact includes enhanced addressing accuracy and administrative efficiency, demonstrating scalability potential. The practice is replicable with clear methodologies, benefiting regions facing similar challenges in spatial data management. Sustainability is ensured through continuous adaptation and alignment with regional priorities. Innovations in data integration and methodology make it a model for transformative change. Linked to the thematic focus on data and open data, it supports improved public services and economic development through informed decision-making. Overall, CDAU's alignment with Interreg goals, demonstrated impact, replicability, sustainability, innovation, and thematic relevance make it a valuable practice for other regions to learn from and potentially adopt.
