This article attempts to assess ‘coastal premiums’ for apartment prices in Corsica, France. The coastal premium should consist of two parts, those related to the view of the Mediterranean Sea, and those associated with living close to beaches for access purposes. Views, being a qualitative and subjective variable, are difficult to measure and quantify. Further, apartments are located in neighbourhoods and then are situated in districts or at more aggregated levels. This induces complex spatial interactions. To deal with these, we first employ a viewshed analysis implemented in geographical information systems (GIS) to generate an objective, continuous measurement. We then develop a Bayesian spatial/spatiotemporal multilevel model, which integrates Leroux’s conditional autoregressive process with multilevel modelling for conducting a hedonic analysis in the presence of multiple-scale housing data. Since the developed model pertains to latent Gaussian models, estimation is carried out by integrated nested Laplace approximations. The results demonstrate that homebuyers have a higher marginal willingness to pay for larger views of the sea, and proximity to beaches produces positive impacts on apartment sale prices. Further, strong spatial spillovers emerge among high-level units, but heterogeneity dominates among apartments. Our findings illustrate the importance of coasts to homebuyers. Further, the estimated value permits planners and policymakers to assess the trade-off between developing and preserving land along the coast.

Abstract. Liquefaction causes secondary damage after earthquakes; however, liquefaction related phenomena were rarely reported until after the Mw = 5.4 November 15, 2017 Pohang earthquake in Korea. Both the Mw = 5.8 September 12, 2016 Gyeongju earthquake and Mw = 5.4 November 15, 2017 Pohang earthquake occurred in the fault zone of Yangsan City (located in the south-eastern part of Korea), and both of these earthquakes induced liquefaction. Moreover, they demonstrated that Korea is not safe against the liquefaction induced by earthquakes. In this study, estimations and calculations were performed based on the distances between the centroids of administrative districts and an epicenter located at the Yangsan Fault, the peak ground accelerations (PGAs) induced by Mw = 5.0 and 6.5 earthquakes, and a liquefaction potential index (LPI) calculated based on groundwater level and standard penetration test results from 274 locations in Kimhae City (adjacent to the Nakdong river and across the Yangsan Fault). Then, a kriging method using geographical information systems was used to evaluate the liquefaction effects on the risk levels of facilities. The results indicate that a Mw = 5.0 earthquake induces a small and low level of liquefaction, resulting in slight risk for facilities, but a Mw = 6.5 earthquake induces a large and high level of liquefaction, resulting in a severe risk for facilities.

AbstractExperience through sight has been recognized as a contributing factor in the shaping of historic landscapes, where humans could express themselves in response to their aesthetic and intellectual qualities. What was experienced, however, was not only dependent on the ‘prospect’, or landscape view, but also on the individual ‘perspective’ of the spectator. Three-dimensional Geographical Information Systems (3D GIS) has enabled investigations into landscape visibility within digitized historic environments and can therefore assist the analysis and understanding of this phenomenon. This article applies 3D GIS to a currently under-researched area of landscape history, English designed landscapes of the 16th and 17th centuries. From country houses and gardens to parks and working estates, these landscapes were manipulated in response to the landowners’ ‘perspectives’ towards the landscape, which subsequently determined the visibility or invisibility of features within certain ‘prospects’. This concept was dubbed ‘The Royaltie of Sight’ by Henry Wotton in 1624. By using 3D GIS to recreate a designed landscape that poses challenges which have previously hindered its analysis, the characteristics of ‘prospects’ can be ascertained using viewshed analysis and the individual ‘perspective’ of the landowner interpreted using phenomenology and reception theory. The results presented in this article demonstrate how 3D GIS has benefited studies into English designed landscapes and improved knowledge of how perception influenced landscape change.

Changes in leaf morphological characteristics in Potentilla fruticosa growing under the transport and industrial pollution conditions in the city of Novosibirsk have been studied. Leaf morphological characteristics were determined by computer image analysis using geographical information systems (GIS). It was found that, in response to anthropogenic disturbance, the size of the assimilating organs of plants decreased by a factor of 1.2-4.5 and the leaf fluctuating asymmetry increased compared to these parameters in control plants; the urban area had a high level of environmental pollution, and the control area a low level.

High Level

One of the main topics in geographical information systems (GIS) research concerns the definition of high level visual query languages (Chrisman, 2002; Laurini & Thompson, 1992). This arises from the need to provide the user with a visual interactive tool for data manipulation and retrieval that is independent of the data’s physical organization. The use of standard query languages for spatial data handling (Rigaux, Scholl, & Voisard, 2001; Shekhar et al. 1999) has been hindered by the lack of appropriate language support. In fact, in visual query languages for GIS, a query can lead to multiple interpretations (Favetta & Aufaure-Portier, 2000).

To develop a protocol to guide pasture sampling for estimation of paddock pasture mass in hill country, a range of pasture sampling strategies, including random sampling, transects and stratification based on slope and aspect, were evaluated using simulations in a Geographical Information Systems computer environment. The accuracy and efficiency of each strategy was tested by sampling data obtained from intensive field measurements across several farms, regions and seasons. The number of measurements required to obtain an accurate estimate was related to the overall pasture mass and the topographic complexity of a paddock, with more variable paddocks requiring more samples. Random sampling from average slopes provided the best balance between simplicity and reliability. A draft protocol was developed from the simulations, in the form of a decision support tool, where visual determination of the topographic complexity of the paddock, along with the required accuracy, were used to guide the number of measurements recommended. The protocol was field tested and evaluated by groups of users for efficacy and ease of use. This sampling protocol will offer farmers, consultants and researchers an efficient, reliable and simple way to determine pasture mass in New Zealand hill country settings. Keywords: hill country, feed budgeting, protocol pasture mass, slope

Proceedings of the International conference (ИнтерКарто. ИнтерГИС, Russia) devoted to geographical information systems for sustainable development of territories have been published annually since 1994. The articles discuss theoretical and methodological aspects of geoinformation support for environmental, economic and social aspects of sustainable de­velop­ment, issues of geoinformatics, cartography, remote sensing of the Earth, problems of environmental sustainability and environmental impact assessment. Over a quarter of a century, the conference proceedings got more than 125 articles related to the use of geoinformation technologies to the study and mapping of vegetation. The review of proceedings gives the concrete examples how to solve problems of vegetation mapping using GIS, it is focused on publications providing some examples of GIS appli­cation to the vegetation studies. The review is organized into thematic sections according the field of application of Geoinformatics: 1.Vegetation, 2. Dynamics, state and ecological functions of vegetation, 3. Biodiversity and its assessment, 4. Plant resources, 5. Monitoring of vegetation. The Vegetation section contains publications on vegetation studies and mapping performed for some regions of Russia — the North of the Far East, the Republic of Sakha (Yaku­tia), the Tyva Republic, Central Siberia, and others. More than half of the articles are devoted to vegetation dynamics, state and ecological functions of vegetation at different hierarchical levels. Some papers present the results of the studies based on new types of information sources (photographs) and visualization methods (animation). The use of geoinformation technologies to study biological diversity was included in the agenda of five conference sessions and later reflected in more than ten publications. They cover the development and creation of GIS, the use of geoinformation technologies for the analysis, assessment and mapping of biodiversity, for its monitoring and conservation. Quite a large number of articles are devoted to the study of forest resources. GIS technologies were used to solve problems of forest management, cartometric analysis of forested areas, determination of taxation indicators, systematization of forest conditions, etc. Examples of geoinformation versatile research for medicinal plant resources are given to assess their quality, resources and productivity in the region, to identify growing areas, including ones to be protected. Most of the published materials concerning to vegetation monitoring mainly relate to forests and forest management.
