A comparison is made between the land administration systems in Spain and Colombia, examining the various organizations that have responsibilities in cartography, cadastre, and property registration. A brief introduction to each organization is provided. Subsequently, to facilitate a general comparison of the main differences and similarities, aspects such as the ministry affiliation, primary purpose, management type, age of legislation, basic management unit, type of registration, scales, continuity of geographic information, data protection policy, valuation, etc., are studied. In the case of Spain, the key national organizations involved are the National Geographic Institute (IGN), the Directorate General for Cadastre (DGC), and the Spanish Land and Trade Registrars Association (CORPME). In Colombia, the Agustín Codazzi Geographic Institute (IGAC) and the National Land Agency (ANT) and the Superintendencia de Notariao y Registro (SNR), as well as the group of more than 45 cadastral managers authorized at the sub-national level, etc. Finally, the lack of land security in Colombia is explained by the lack of a good cadastre.

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.

It is widely accepted that old cadastral maps have multiple uses, such as reestablishing cadastral parcel boundaries, municipality boundaries, and coastal limits, or conducting historical, economic, and social studies. In Spain, the Directorate General for Cadastre, and the National Geographic Institute, has numerous digitized old maps that are accessible to users. In the Comunidad Valenciana, the georeferencing of certain series of old cadastral maps is being carried out in phases, which is one of the subjects of this study. A metric analysis of two series of old cadastral maps from a municipality was conducted. One of the series was georeferenced by the Valencia Provincial Cadastre Office, while the other was georeferenced in this research. Additionally, a spatial data infrastructure (SDI) was created, providing WMS, catalog, and document download services. Metadata were also published, containing information about the source, digitalization process, georeferencing, and achieved accuracy, following the ISO 19115 standard for geographic metadata. Furthermore, through individual and group interviews, participatory social research was conducted, to assess the use of old cadastral maps and the created SDI services, aiming to understand the users' appreciation of the services. The results of the social research indicate that the SDI services created are highly valued, but certain conditions need to be met to ensure their effective use by the general public in order to avoid misuses and misinterpretations.

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.

Image-based and range-based solutions can be used for the acquisition of valuable data in medicine. However, most of these methods are not valid for non-static patients. Cranial deformation is a problem with high prevalence among infants and image-based solutions can be used to assess the degree of deformation and monitor the evolution of patients. However, it is required to deal with infants normal movement during the assessment in order to avoid sedation. Some high-end multiple-sensor image-based solutions allow the achievement of accurate 3D data for medical applications under unpredicted dynamic conditions in consultation. In this paper, a novel, single photogrammetric smartphone-based solution for cranial deformation assessment is presented. A coded cap is placed on the infant's head and a guided smartphone app is used by the user to acquire the information, that is later processed on a server to obtain the 3D model. The smartphone app is designed to guide users with no knowledge of photogrammetry, computer vision or 3D modelling. The processing is fully automatic offline. The photogrammetric tool is also non-invasive, reacting well with quick and sudden infant's movements. Therefore, it does not require sedation. This paper tackles the accuracy and repeatability analysis tested both for a single user (intrauser) and multiple non-expert user (interuser) on 3D printed head models. The results allow us to confirm an accuracy below 1.5 mm, which makes the system suitable for clinical practice by medical staff. The basic automatically-derived anthropometric linear magnitudes are also tested obtaining a mean variability of 0.6 ± 0.6 mm for the longitudinal and transversal distances and 1.4 ± 1.3 mm for the maximum perimeter.

The valuation regulations in the context of expropriation in Spain avoid valuation by comparison to prevent discretion, considering the need for market information. Therefore, it defines the capitalization of rents, corrected with a location factor that considers the location rent as the land valuation method. However, a certain lack of precision in the regulations is detected when determining the location factor, so certain aspects to be considered when calculating the location factor are left to the valuer's interpretation. As a result, controversies arise that affect the final value of the calculated location factor, and therefore the value of the land subject to expropriation, between the conflicting parties--the beneficiary and the expropriated party. The GeoValoracion software has been designed as a geoportal, which offers a simple calculation of the location factor, with a detailed description of the interpretation of the parameters and the calculation procedure. Its use in legal procedures can prevent discretionary interpretation and definition by the parties, providing some clarity in calculating the expropriated land value. [ABSTRACT FROM AUTHOR]

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]

To understand soil erosion processes, it is vital to know how the weather types and atmospheric situations, and their distribution throughout the year, affect the soil erosion rates. This will allow for the development of efficient land management practices to mitigate water-induced soil losses. Vineyards are one of the cultivated areas susceptible to high soil erosion rates. However, there is a lack of studies that link weather types and atmospheric conditions to soil erosion responses in viticultural areas. Thus, the main aim of this research is to assess the impacts of weather types and atmospheric conditions on soil erosion processes in a conventional vineyard with tillage in eastern Spain. To achieve this goal, rainfall events from 2006 to 2017 were monitored and the associated runoff and soil loss were collected from experimental plots. Our results showed that the highest volume of runoff and soil erosion is linked to rainfall associated with the eastern winds that accounted for 59.7% of runoff and 63.9% of soil loss, while cold drops in the atmospheric situation classifications emerged as the highest contributor of 40.9% in runoff and 44.1% in soil loss. This paper provides new insights into the development of soil erosion control measures that help to mitigate the negative impact of extreme rainfall and runoff considering atmospheric conditions.
