A cadastre, as one of the key registers of land administration, must be maintained to provide up-to-date land information. Before digitization, technical and alphanumerical datasets were maintained separately, leading to redundant data. This resulted in numerous inconsistencies between the cadastral map and the register, leading to the loss of integrity of these authoritative data. The fact that the cadastral map and the register are in the electronic form today does not guarantee their integrity and quality. The aim of this research was to develop a methodology for analyzing and resolving the inconsistencies between a cadastral map and a register, which were indicated by the differences found in the quality controls in cadastral map vectorization projects. A detailed analysis of the differences between the cadastral map and the register data resulted with systematization of causes and the sources of errors, which then led to the inconsistencies between the two cadastral datasets. The cadastral datasets required for such an analysis were scanned and georeferenced cadastral map sheets, vectorized cadastral map, and vectorization reports. The proposed methodology was tested on three cadastral municipalities in Croatia, namely Dol, Postira, and Stobreč. A detailed analysis of each individual inconsistency showed that the inconsistencies were caused not only by the maintenance errors but also by other processes that affected the cadastral datasets throughout their lifetime.

A systematic approach to the establishment of the Franciscan Cadastre, which has been performed in most Central European countries, has resulted in the following documents: cadastral maps, cadastral municipality boundary demarcation records, lists of land parcels, lists of building parcels and lists of possessors. The documentation, which is stored in various archives, is digitized and made available to users through catalogs. The availability of documentation was examined in this study using three services in the catalogs—discovery, view and download—of which the largest percentage of documents is available through the discovery service. Documents that are available through the discovery service are described by the metadata standards. In this study, we examined the applicability of geographic information metadata standards and metadata standards to archival documentation in catalogs in which cadastral documentation was found. We determined a lack of application of geoinformation metadata standards, as it was a cadastral dataset, which represented one of the fundamental spatial datasets. The semantic mapping of elements between the applied standards in the catalogs and the geoinformation metadata standard (ISO 19115) showed that it was possible to apply the ISO 19115 standard to documents resulting from the establishment of the cadastre.

Land administration systems differ by their types and practices. The data dissemination practices are considered to be outdated, as in most cases the digitisation of land administration data was conducted to match the paper-based system. This paper reviews four different land administration data dissemination practices through four case studies, where each selected jurisdiction represents one land administration system type. The analysed LAS data dissemination practices were conducted for Croatia, England, New Zealand and Green County, OH, USA. The main goal of the analysis was to examine the differences and similarities between the respective countries’ land data practices provided by the excerpts related to one parcel. The identified differences and similarities might be of great use when it comes to further improvement and standardisation of land administration data dissemination practices.

During the summer period, fire hazards represent an especially real threat not only for vegetation and animals, but also for material resources and human lives. In the Republic of Croatia, the most affected areas are those in the coastal region, which are characterised by a very dry environment and strong winds that are conducive to the rapid spread of wildfire. Although the prevention of wildfire is an utmost imperative, many countries are still missing a good and reliable fire management system for both fire monitoring and prevention and post-disaster management. The aim of this paper is to show the utilisation of open source GIS, web-based technologies, and open data in the case of natural disasters, and to define the concept of advanced national system of compensation determination. Such a system could be utilised to identify land parcels for which compensations for damage and losses after fire devastation have to be determined and could be used by compensation agencies, insurance companies, or state administration. The island of Hvar, which has suffered from fire hazards, was used as a case study for a quick and relevant calculation of the compensation based on land administration data. Sentinel satellite images and official digital orthophoto maps (DOMs) of the affected area before and after the fire devastation were obtained and analysed together with the data on cadastral parcels and land owners. Research was conducted by using both sets of imagery data, showing that Sentinel satellite images are more than adequate for fulfilling the task of the determination of hazard compensation.

The systematic approach to the establishment of a cadaster in most European countries has resulted in a variety of cadastral documents. Most official cadastral data are from the 19th and 20th centuries and are stored as hard copies or electronic data in a data warehouse, while the original documents are stored in analog format in separate locations, making the cadastral data difficult to access. The increasing interest in the use of archival cadastral documents has stimulated their digitalization in most countries, allowing users to access cadastral documents through metadata catalogs. Most catalogs use archival metadata standards to describe cadastral documents, with a lack of application of geoinformation metadata standards that represent fundamental spatial datasets. Archival metadata standards do not provide enough information about the origin and quality of cadastral data. The aim of this study was to examine the applicability of the ISO 19115-1 standard for describing cadastral documents. The methodology includes a comparison and an analysis of documents which are stored in different locations. The metadata of archived cadastral documents are recorded in archive inventories, and archives use different terminology for documents with the same content. The scientific contribution of this study is given by the classification of key documents and their associated properties that uniquely described each document. Four types of documents were classified by comparison, and we analyzed the content between documents. Property identification resulted in the semantic mapping to metadata elements of ISO 19115-1 and showed a considerable congruence of elements. It was possible to apply the ISO 19115-1 standard for describing documents of systematic cadaster establishment, with additional extensions for some elements. Proposed extensions to describe the cadastral documents include replacing free text with domains of appropriate values, adding stricter obligations, and restricting the use of domain values. The standardization of metadata for analog cadastral documents in archives has created a prerequisite for the development of a metadata catalog, which would increase the availability and accessibility of cadastral data for different user groups.

In the Republic of Croatia, especially during the summer times, fire hazards represent a real threat for vegetation and animals but also for material goods and human lives. The most affected areas are those in the coastal region which is characterized by very dry environment and strong winds which is suitable for rapid spread of fire. Even though the prevention of fire is an utmost imperative, Republic of Croatia is still missing a good and reliable fire management system for fire monitoring but also for post-disaster management. The results of currently ongoing scientific project “Development of Multipurpose Land Administration System – DEMLAS” could be of an assistance. The aim of the DEMLAS project is to create a prototype of a modern multipurpose land administration system that supports all land governance activities. It could be used for identifying dangerous locations where fires repeatedly occur and together with other relevant data provide a solution for better monitoring and prediction of the fires. It could also be used for identifying the land parcels for compensations for damages and losses after the fire devastations. The Island of Hvar which is also affected by this problem will serve as a test case for quick and relevant calculation of compensations based on official registered data.
