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.

This paper presents a methodology for performing electoral geomarketing to identify potential voters from each political party and to understand their characteristics. Such information can be useful for optimizing the resources of a political party when preparing the election campaign. In this paper, a statistical study is conducted to analyze the relationship between electoral data and several socio-demographic, dependence, migratory, economic, and educational variables. A geoportal, called Geo- Chess (https://upvusig.car.upv.es/geochess/) is used to create all the thematic maps, graphs, and the majority of statistical studies. The geoportal permits visualization of the thematic maps and graphs shown in this work. [ABSTRACT FROM AUTHOR]

Quantifying the effect of location on land values can be done by designing a location factor which considers the most relevant aspects that may influence this value such as proximity to large cities, the population living around the parcel or land to be valued, the distance from it to markets or logistic centres, or the existence of places of environmental or landscape interest. Considering these variables can be complicated by having to process large amounts of distinct data (distances, no. of inhabitants or population size, protected areas, etc.), which have to be processed and interpreted to be able to define the factor that summarises them, and can affect the land value from income, such as productive assets, to correct its value. The main proposal put forward in this research is to study the various location aspects that affect land values, and the possibilities that Geographic Information Systems (GIS) offer to design with free software tools that allow simple calculations of a location correction factor and, consequently, land values. Calculations were made for all the rural cadastral parcels (2.3 million) in the Valencian Region. Results can be integrated into a new online GIS portal and make these available to users in soil valuation studies. [ABSTRACT FROM AUTHOR]

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.

Since ancient times, human beings have been interested in knowing their environment in order to make the right decisions in territorial management. The spatial component is a feature of great importance in the assets that surround us. Heritage geoinformation is a convenient and effective way for management, protection and safeguarding of cultural and natural heritage. For optimal compliance, it is nowadays indispensable to rely on the use of new web technologies and geomatics knowledge that allow the documentation, visualisation, monitoring and management of heritage. Therefore, the main objective of this article is to develop a web-based cultural heritage management system in Cantón Nabón, Ecuador, as a case study. The system, consisting of a web-based geoportal accessible to the whole society, will allow consulting the geolocalised heritage information of the study area on a virtual map, as well as 3D geovisualisation in an interactive web viewer. The integrated system, once implemented, will take into consideration the preventive conservation cycle in the heritage field, highlighting, in Spanish, the creation of the heritage data models according to ISO21127:2014.
