The dynamics of societal material stocks such as buildings and infrastructures and their spatial patterns drive surging resource use and emissions. Two main types of data are currently used to map stocks, night-time lights (NTL) from Earth-observing (EO) satellites and cadastral information. We present an alternative approach for broad-scale material stock mapping based on freely available high-resolution EO imagery and OpenStreetMap data. Maps of built-up surface area, building height, and building types were derived from optical Sentinel-2 and radar Sentinel-1 satellite data to map patterns of material stocks for Austria and Germany. Using material intensity factors, we calculated the mass of different types of buildings and infrastructures, distinguishing eight types of materials, at 10 m spatial resolution. The total mass of buildings and infrastructures in 2018 amounted to ∼5 Gt in Austria and ∼38 Gt in Germany (AT: ∼540 t/cap, DE: ∼450 t/cap). Cross-checks with independent data sources at various scales suggested that the method may yield more complete results than other data sources but could not rule out possible overestimations. The method yields thematic differentiations not possible with NTL, avoids the use of costly cadastral data, and is suitable for mapping larger areas and tracing trends over time.

Planetary geological-geomorphological mapping has some peculiarities which need to be addressed in order to standardize the technical and scientific approach. The aim of this project is the attempt to apply the cartographic standards rules used in the Italian Geological Mapping Project
(CARG Project) for the realization of geological and geomorphological
maps at various scales of detail even in the planetary environment.
Satellite navigation systems are more and more used in geomatics.
This penetration has not always taken into account the relative safety and security aspects and the consequent threats to humans. This work focuses on these aspects that are often overlooked in geomatics. After a brief introduction
on the evolution of satellite navigation systems and on future trends, the related safety and security risks are analyzed and possible countermeasures (Integrity, Awareness and Protection) are discussed.

The issue of the existing agricultural land improvement effectiveness in the course of land reform is scrutinized in the article. The research relevance is predefined by the need for the fragmented land ownerships and tenures optimization as a constituent of the sustainable land tenure in Ukraine. Land plots exchange approaches substantiation in the course of the existing agricultural land tenure improvement under current social and economic conditions is the goal of the research. Key aspects of land exchange aiming at land tenure optimization within the agricultural land mass in accordance to the legislation in effect have been exemplified. Sources of the existing agricultural land tenures and land ownerships drawbacks have been singled out. Land tenure areas of agricultural enterprises situated in Ukraine and Kyiv Region have been analyzed. Land plots exchange based on a set of qualitative, spatial and technological characteristics has been carried out on the example of an agricultural enterprise in Kyiv Region. As the result, the improvement of the agricultural enterprise land tenure spatial characteristics including furrow length has been achieved. The research results can be used at the existing land tenure and land ownership improvement in accordance to the legislation, the land consolidation strategy development in Ukraine, land owners and land users private efforts and the scientific researches in the future.
A digital twin can be defined as a realistic representation of something physical. To improve decision making, a reliable digital twin of the underground is required. Utilities represent a significant portion of physical assets existing underground. Most of these utilities are situated in the relatively shallow layers of the underground, up to a few meters below the surface. The reliable information on subsurface utilities has clear benefits all throughout the life cycle of state land, resulting in efficient decision-making processes, cost savings, and additional revenues for land administration professionals. However, the lack of a reliable map of subsurface utilities lead to ill-informed decisions, costly information gathering, and missed business potential. This paper will share a case study of the 3D underground utility mapping workflow from data capture to usage in Singapore. The new data is collected by the Pegasus: Stream, a mobile mapping platform which captures above and underground data using the photo, laser and ground penetrating radar technology. Based on the Land Administration Domain Model (LADM) 3D underground utility data model, the new collected data is used with the existing utility and cadastral data for land administration. This study case expects to explore the reasonable workflow of 3D underground utility mapping to provide reliable information for land administration.
As a result of the research, it was found that the lack of formed and
established boundaries in newly formed territorial communities significantly affects
the implementation of land management within their territory, the reliability of land
registration and statistical reporting, the flow of funds to local budgets, the efficiency
and rationality of the use of natural resources, which complicates the activities of local
self-government bodies. It was clarified that the implementation of projects for the
formation and establishment of boundaries of village and settlement councils was not
carried out, that is, the formation of their boundaries took place only on paper without
verification on the ground, and as a result, inaccurate areas and limits were obtained.
These measures may be introduced in case of implementation of the proposed changes
to the Land Code of Ukraine and the Law of Ukraine "On Land Management". The
expected results are presented in the event of implementation of these measures.
Abstract The cadastral data, including land parcels, are the basic reference data for presenting various objects collected in spatial databases. Easy access to up-to-date records is a very important matter for the individuals and institutions using spatial data infrastructure. The primary objective of the study was to check the current accessibility of cadastral data as well as to verify how current and complete they are. The author started researching this topic in 2007, i.e. from the moment the Team for National Spatial Data Infrastructure developed documentation concerning the standard of publishing cadastral data with the use of the WMS. Since ten years, the author was monitoring the status of cadastral data publishing in various districts as well as participated in data publishing in many districts. In 2017, when only half of the districts published WMS services from cadastral data, the questions arise: why is it so and how to change this unfavourable status? As a result of the tests performed, it was found that the status of publishing cadastral data is still far from perfect. The quality of the offered web services varies and, unfortunately, many services offer poor performance; moreover, there are plenty services that do not operate at all.

More and more historical data are available on the web. In France, old cadastral maps are regularly published by the “départements”. Such material is relevant to various applications (on-the-field search of specific objects such as old boundary stakes, historical studies of demography, human activities, land cover…). The GeF laboratory is working on the development of a complete methodological toolchain to vectorise, correct and analyse cadastral parcels and their evolution, using open source software and programming language only (QGIS, GDAL, Python). This article details the use of a part of this toolchain - georeferencing old cadastral data - on parcels located near the Loir river, in two villages of southern Sarthe: Vaas and Aubigné-Racan. After a presentation of our methodological toolchain, we will discuss our first results.
Quest’articolo parte dallo studio delle città portuali storiche, siti UNESCO, che oggi affrontano la sfida della riqualificazione dei waterfront urbani attraverso la conservazione del patrimonio culturale e paesaggistico. Le raccomandazioni sull’ “Historic Urban Landscape”, e gli strumenti operativi promossi dall’ICOMOS “Guidance on Heritage Impact Assessments for Cultural World Heritage Properties” del 2011, si configurano come le più recenti disposizioni concernenti la conservazione, protezione e valorizzazione del patrimonio culturale (Fusco Girard, 2010). La Guida ICOMOS è stata considerata lo strumento più adatto per valutare gli impatti dei grandi progetti di riqualificazione dei waterfront urbani sul patrimonio culturale. Per comprendere al meglio tale strumento è stata fatta un’applicazione per valutare gli impatti del Grande Progetto Pompei sul waterfront di Torre Annunziata, città costiera nel Golfo di Napoli sito UNESCO. A questa fase di analisi segue una riflessione su come migliorare l’Heritage Impact Assessment, come strumento capace di valutare non soltanto gli impatti culturali ma anche quelli economici, per parlare di “economia del patrimonio culturale”. La proposta ultima è quella di affiancare al processo di “Heritage Impact Assessment” una valutazione degli impatti economici, attraverso un’analisi costi-benefici, per quantificare in termini monetari la convenienza degli investimenti nella conservazione del patrimonio storico urbano delle città costiere, proponendo una “Economic Heritage Impact Assessment” (EHIA). Tale metodo, elaborato dall’autrice all’interno della tesi di dottorato “Il paesaggio storico urbano delle città costiere: sfide e opportunità. Il caso Torre Annunziata”, offre la possibilità di superare la sola valutazione degli impatti culturali proposta dall’ICOMOS.
Many companies are beginning to use BIM software or have already started but
have stalled. We see 10 rules to follow to ensure that the transition from CAD to BIM of a project department can be successful. Of all the activities related to the life of a building, embraced by BIM methodology, we focus today on those related to the design. Proceed by steps, to dedicate a small team, well-chosen and motivated, understand right away the new workflow, are some of the tips of the article. These tips do not cover all the things you need to know to start a BIM process but I believe they can help to avoid the most common mistakes that you make at the beginning of the journey. We use the BIM process because it gives us benefits. Because it saves time and makes us produce work of the highest quality. If we do not reach this convenience means that in our process BIM's about to change.
The aim of the study is to show, how and how much, urbanization and soil sealing can change the hydraulic performance of a given geomorphology. The analysis area includes the territory of the ex Consortium for Land
Reclamation Medio Astico Bacchiglione; a specific test was performed to Municipality of Thiene (Province of Vicenza). Thanks to a dedicated spatial algorithm developed with ArcGis it was possible to correlate, per pattern of land use, the runoff coefficients at the digital terrain model (DTM). The implementation of the functions of direction and accumulation (hydrology tools), has allowed to study the behaviour of the superficial runoff and to evaluate the hydrological impacts per use change, of two reference periods (1954 and 2006).
The test generates the risk mapping. Areas at different vulnerability and exposure are identified with tool focal statistics. Referred to them are the spatial planning strategies on watershed scale. The algorithm in GIS environment allows to manage flood risk with multiscale and multitemporal analysis of the dynamics of land use, and to estimate the incremental levels of soil sealing and cumulative impacts. Hazard and risk are managed with a complete overview of the problem; it allows to check, in time, the uses at high impact and the health risk. The obtained results support the urban regeneration
policies and the territorial development.
Abstract. Advancements in satellite sensor technology enabling capturing of geometrically accurate images of earth's surface coupled with DGPS/ETS and GIS technology holds the capability of large scale mapping of land resources at cadastral level. High Resolution Satellite Images depict field bunds distinctly. Thus plot parcels are to be delineated from cloud free ortho-images and obscured/difficult areas are to be surveyed using DGPS and ETS. The vector datasets thus derived through RS/DGPS/ETS survey are to be integrated in GIS environment to generate the base cadastral vector datasets for further settlement/title confirmation activities. The objective of this paper is to illustrate the efficacy of a hybrid methodology employed in Pitambarpur Sasana village under Digapahandi Tahasil of Ganjam district, as a pilot project, particularly in Odisha scenario where the land parcel size is very small. One of the significant observations of the study is matching of Cadastral map area i.e. 315.454 Acres, the image map area i.e. 314.887 Acres and RoR area i.e. 313.815 Acre. It was revealed that 79 % of plots derived by high-tech survey method show acceptable level of accuracy despite the fact that the mode of area measurement by ground and automated method has significant variability. The variations are more in case of Government lands, Temple/Trust lands, Common Property Resources and plots near to river/nalas etc. The study indicates that the adopted technology can be extended to other districts and cadastral resurvey and updating work can be done for larger areas of the country using this methodology.
