This work goal is to evaluate the use of cadastral information -geographical and literal- to determine and quantify the changes in crop types between two dates. The changes in an agricultural area of the Alboraya municipality since 1930 are studied. As information source, the cadastral parcel data of the cadastral polygon 4 of the municipality is studied. The Topographical Cadastral Map (TCM) of 1930 is used as old cadastral information, and the associated listing of parcels in paper format. This old information is compared with the current cadastral information. This research compares the crops registered on both dates. Along the process, the factors, characteristics and conditions to accomplish by the information of the study are also studied - availability, format, age, production technique, and georreferencing- to evaluate the method's advantages and limitations. As conclusion, remark on the utility of the old cadastral maps to detect crop changes. The TCM use allows quantifying and delimitating the produced changes in each territory element with detail.

Ever since the Cadastre and Land Registry have existed in Spain, they have been completely separate organisations with very different objectives, which influence the real-estate reality. Their coordination is essential to better identify buildings and to more suitably render services to citizens and Administrations. To this end, Law 13/2015 was passed in 2015 for this desirable and pressing Cadastre-Land Registry coordination to come about. This law came into force on 1 November 2015, and coincided with the development of the technical aspects of the graphical information exchange among the Cadastre, Land Registries and Notaries. Several ministries and different organisations, like the Cadastre personnel, jurists, technicians, and even citizens, are implied in this law. Among the technical aspects, georeferenced graphical representations and GML exchange files adapted to the European INSPIRE directives stand out. Such technical aspects are a genuine revolution as they were transferred to the legal world. After more than 2 years after its application, it is still in its initial and adaptation stages because it is a long-standing law that allows land registry units-cadastral parcels to be coordinated while they are incorporated into real-estate trade.

The communication capacity of the cartographic representation has increased its use in all areas of administration. Nowadays, cartographic projects are part of a multitude of procedures in the local administration. They allow as to define, in a graphic and efficient way, the different actions that are carried out over the entire territory of a municipality. In this article, the different phases in which the cartographic representation intervenes in the local administration are classified and enumerated, basically referring to the sections on the production, management and distribution of cartographic products. We highligh the support tasks of the specialist in these issues. These products are studied through applications of the real case of the municipality of Torrent (Valencia, Spain), after years of experience and been put into practice in the council of this town. Finally, the regional, state and European laws in cartographic area or cartography are highlighted too. [ABSTRACT FROM AUTHOR]

The old cadastral maps of the Spanish General Directorate for Cadastre (DGC) have always been in great demand. It was decided in 2012 to make an initial inventory of these maps with the type of information available, physical location, and condition. Subsequently, to evaluate their possible use, the inventory was examined to investigate whether these maps could be geographically referenced and made available on a geoportal. Several years later, it was determined that the inventory needed to be updated with a series of improvements (expanding the fields so that they become clearer, homogeneous, and more easily handled by software). A questionnaire was issued to technical specialists on property boundaries. As a principal conclusion we can highlight that the use of old cadastral maps in Spain is of great importance. The information on these maps is widely demanded by technical and legal experts who consider that an update and revision of the DGC inventory is essential. It is crucial that old cadastral maps are digitised and made available online, preferably free of charge and through an easy-to-use geoportal. The information on these maps helps to resolve property boundary disputes and has many other uses. Investment in the economic and human resources needed to preserve and publish these maps is essential given their great value. • Inventory of available cadastral maps. • Survey on the use of old cadastral maps. • Old cadastral maps used to help resolve property boundary disputes. • Old maps in Spain. • Maps accessible through a geoportal.
