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.
