[EN] A necessary and effective coordination between cadastre and land registry has always existed in Spain, but the difficulties have only been specifically addressed in the last few years. The aim of this study is to illustrate, analyse, and evaluate advances in this coordination in Spain from the beginnings of the current system in the early twentieth century, with the cadastre and land registry operating as separate organisations. A preliminary study was made in 2002 of the difficulties that needed to be overcome to achieve an ideal coordination of mainly mapped information. The study was made by gathering and analysing the opinions of various specialists who have dealt with the issue of coordination. For this research, qualitative information (current and historical) was gathered by querying documents about cadastre and land registry coordination in Spain. This information was studied and compared to identify the problems and challenges. A survey in 2012 analysed the relationship between the cadastre and land registry from the point of view of the general public in the city of Gandia. The Spanish government enacted the first specific and effective legislation on coordination in 2015 (Act 13/2015), and much has changed since its introduction. During the last five years of application, each of the problems initially highlighted has been monitored and analysed, and the difficulties that have arisen have been noted. In this study, each of these problems and challenges is analysed from various perspectives: querying documents (norms, budgets, official news, etc.), websites, digital applications, observation, and interviews. The main results of the case study in Spain are as follows: coordination is generally indispensable and cannot be postponed; there is a difficult understanding between the organisations involved; the general public associate the word ¿cadastre¿ with taxes and not with security in the demarcation of property; political will and understanding is necessary; the process is slow and requires ...

[EN] This article presents a study based on the outputs from the LUISA Territorial modelling platform (Joint Research Centre of the European Commission) focused on regional and local future projections of land abandonment between 2015 and 2030. Spain is taken as representative of one of the countries highly affected by agricultural land abandonment in the European Union. The most relevant factors driving land abandonment (biophysical, agroeconomics, farm structure and demographic) are described and mapped. Results from the analysis reveal that the Galicia region, northern Spain (Asturias, Cantabria, Gipuzkoa, Bizkaia), north-eastern Spain (Aragon region), central Pyrenees/Ebro basin (Huesca, Navarra, Lleida) and south-eastern Spain (Murcia, Almeria, Alicante, Malaga) are expected to undergo important abandonment processes. The study also concludes that land abandonment within mountainous, high nature value farmland and Natura 2000 areas is lower compared to the outside area without conservation and protection measures ; Perpiñá Castillo, C.; Coll-Aliaga, E.; Lavalle, C.; Martínez Llario, JC.

[EN] A rule-based topology software system providing a highly flexible and fast procedure to enforce integrity in spatial relationships among datasets is presented. This improved topology rule system is built over the spatial extension Jaspa. Both projects are open source, freely available software developed by the corresponding author of this paper. Currently, there is no spatial DBMS that implements a rule-based topology engine (considering that the topology rules are designed and performed in the spatial backend). If the topology rules are applied in the frontend (as in many GIS desktop programs), ArcGIS is the most advanced solution. The system presented in this paper has several major advantages over the ArcGIS approach: it can be extended with new topology rules, it has a much wider set of rules, and it can mix feature attributes with topology rules as filters. In addition, the topology rule system can work with various DBMSs, including PostgreSQL, H2 or Oracle, and the logic is performed in the spatial backend. The proposed topology system allows users to check the complex spatial relationships among features (from one or several spatial layers) that require some complex cartographic datasets, such as the data specifications proposed by INSPIRE in Europe and the Land Administration Domain Model (LADM) for Cadastral data ; This work has been partially supported by the research project "Creation and cartographic feeding of spatial data Infrastructures in the local government by means of a data model that integrates cadastre, planning and cultural heritage", CSO2008-04808 from the Spanish Government (CICYT) and the European Union Funds. ; Martínez Llario, JC.; Coll-Aliaga, E.; Nuñez-Andres, M.; Femenia-Ribera, C.

Land demarcation is a fundamental requirement when determining to what extent property owners and public administrations can apply their rights. Just as international boundaries must be clearly marked so that there can be no doubt as to which jurisdiction is to be applied, municipal boundaries must be clearly defined in order to avoid disputes between local administrations. In Spain the Geographical Institute carried out the demarcation of all municipal boundaries at the end of the 19th and beginning of the 20th centuries, defined their limits on cadastral maps and represented them on the 1:50,000 scale National Topographical Map. At the present time, more than a hundred years after this survey, in many cases parts of the original municipal limits have been lost for one reason or another, both on the maps and on the ground itself, and it has now become necessary to take steps to recover them. This paper defines a method of using the municipal councils own historical information to trace original boundary lines. The work included both a study and a series of tests carried out in different municipal areas in the Province of Valencia, Spain. The original reports and field notebooks of the Geographical Institute were used as the basic material of the study, supported by cadastral maps from different periods, as well as historical and contemporary orthophotos to help locate possible boundary markers. GPS techniques were employed to look for, survey and reinstate boundary marker positions. ; This work has been partially supported by the research project 'The Land Registry as the basic tool for organising spatial information; INSPIRE Directive, spatial data and metadata (II)', DER2011-23321 from the Spanish Government. ; Femenía Ribera, C.; Benítez Aguado, E.; Mora Navarro, JG.; Martínez Llario, JC.
