Demand Patterns

Estimating off-road trail usage by nonmotorized modes is of increasing interest to the transportation community due to the rising importance of both recreational and nonmotorized travel. Demand patterns for two substantial off-road trails in Melbourne, Australia, were examined using survey and modeling methods to establish the potential for higher levels of demand. The two trails were different in two major respects: one was well promoted, well connected, and a destination in its own right; the other had similar potential, but the linkages and promotional activity to market its assets had not yet been undertaken. The characteristics of these two markets were examined using geographic information systems (GIS) methods and demand estimated on a differential basis using GIS tools. The simple method adopted highlighted the critical nature of marketing a connected series of off-road trails as a single unified route and an easily recognized destination area. The study had to be done using existing data, and it provides a means of combining transportation, GIS, and special-purpose off-road trail usage information to estimate potential demand.

The emerging discipline of health geographics uses the concepts and techniques of medical geography (Meade, Florin & Gesler, 1988) together with modern automated Geographic Information Systems (GIS) methods to investigate health issues (Ricketts, Savitz, Gesler & Osborne, 1994). The main aim of this chapter is to bring the exciting potential contributions inherent in this approach to the attention of health practitioners and researchers. With the development of powerful, yet affordable geo-technologies, digital maps and visual displays are produced that can be used for research, practice and/or health policy analysis. One major advantage of this technology is that complex information can be displayed for the consumer in more intuitive, self-explanatory form. This is accomplished by linking and overlaying health data to standard census geographic areas which can be accessed quickly and flexibly from national and state agencies (Devesa, Grauman, Blor, Pennello, Hoover & Fraumeni, 1999; Kim, 1998). This chapter will illustrate how a GIS-based, multi-method approach can be applied to the study of health disparities. Using the pressing public health issue of access to kidney transplantation in California as an example, we will explore the notion of health disparities using a geographic conceptual framework for studying and understanding existing gaps in transplantations conducted. Different GIS techniques to addressing this issue are presented with a discussion of the relative advantages of each approach and a final review on how to most effectively use a GIS-based approach in studying health disparities.

In this article, we put critical geographic information systems (GIS) methods into conversation with feminist political and economic geographies, mapping the Ugandan wedding industry across the body, city, and the global. In doing so, we ground macro geopolitical and geoeconomic shifts in the lived experiences of women involved in the wedding industry, revealing some of the cross-scalar political economies of the trade. We develop a form of “global intimate mapping” to ask, empirically: how are new transnational trade networks reflected in the cityscape and the bodies of brides? And conceptually: what productive insight does feminist GIS offer for feminist political and economic geographies?

Data Layers

Geographic information systems for transportation (GIS-T) seek to integrate the geospatial approach of GIS and the tabular approach of conventional transportation analysis. GIS-T deals with such topics as network analysis, linear reference systems, travel demand modeling, and intelligent transportation systems. Conventional cartographic treatment of route features is reviewed in the context of the mapping challenges introduced by GIS-T. Problems in the visualization of complex linear data are identified and examined as cartographic design issues. Cartographic requirements are specified for mapping route-based data and basic design issues are identified. The representation of complex route-based data layers is posed as an undeveloped specialty of cartographic design. Some of the issues involved in developing such fundamental principles are summarized and potential avenues of research are suggested.

This chapter introduces the topic of Perceptual Dialectology (PD), an area of sociolinguistics concerned with how nonlinguists understand dialectal variation. The chapter provides a brief history of the field and explores the ways in which the perceptions and language attitudes of nonlinguists have typically been elicited in research conducted within the modern tradition of PD with a particular focus on mental maps. Additionally, this chapter identifies ways in which these methods have been improved upon, specifically through the use of geographic information systems (GIS) tools. As an illustration of both the typical tools used in PD research and these recent advances in data analysis, a research project on the perceptions of dialectal variation within and across the state of Kentucky is presented.

In this study, alternative tourism types and sights belonging to Safranbolu were identified through Geographic Information System (GIS) tools. In this manner, most favorable tourism activities, which are specific to field, and evaluation factors of these activities were determined. “Suitability classification values” of these factors were charted by receiving opinions from experts. Natural and cultural properties of study area were determined in the light of evaluation factors and a database was set via GIS. This database was examined according to evaluation factors of the activities and the most suitable and conditional suitable areas were determined. In this study, it is aimed to carry out the suitable place analysis for alternative tourism types of Safranbolu, which is a tourism town, such as riding, mountain biking, camping, trekking. 486&amp;thinsp;km<sup>2</sup> area for riding, 319&amp;thinsp;m<sup>2</sup> for trekking, 209&amp;thinsp;km<sup>2</sup> for mountain biking and 148 km² for camping were figured out as suitable. These results reveal that tourism activities should be more professionally organized in order to apply alternative tourism types such as riding, mountain biking, camping, trekking. In addition, organizations such as festivals and fairs should be arranged in order to introduce products special to Safranbolu.

<p class="Abstracttext-VITRUVIO">The main objective of the study is to assess, independently of the scenic beauty, the importance and composition of the different attributes within a given landscape. For this purpose, the study focuses on Penyagolosa where we have selected three areas of evaluation to determine the importance of distance in the determination of heritage values of the landscape. Using Geographic Information Systems (GIS) determines what values are detectable on the basis of the terms of proximity and remoteness and how they are applied in three cases of assessment. Thus, 5 criteria have been set to analyze these values: 1. the overview of the landscape, 2. dominance or intensity of elements, 3. the aesthetic composition of space, 4. The selective interpretation of the visual and 5 variables. The fragility or alterations induced in the landscape. Ultimately, criteria are discussed from dynamic and static fields of the authenticity and integrity of the landscape and they affect how they neglect.</p>

Hydropower Potential

<p class="R-AuthorsNames">Hydropower potential studies usually include estimation of hydropower resources and creating propositions for hydropower development on study area. The current paper describes authors’ study, dedicated to development of methodological approaches and software designed for solving problems stated above. Process automation is achieved by using geographic information systems (GIS) and additional programs (Python language was used).</p><p>Hydropower potential estimation is the key element for understanding future prospects of hydropower development within the study area. The latest large-scale hydropower potential studies of Russian territories were held in 1940-1980. In those times, such researches were carried out almost without any automation, so calculation process was time-consuming. As a result, only hydropower potential of large and several medium-sized rivers was estimated; hydropower potential assessments of small rivers were conducted only using approximate approach.</p><p>Nowadays, implementation of technologies and software products, such as geographic information systems, contributes to development of methodologies, which can be used to automate business-processes in different scientific disciplines, including processes of hydropower potential estimation and prospective hydropower plants siting. In comparison with former studies, GIS allow to reduce labor work significantly and to perform analysis of large study areas and large number of streams (including small rivers) in relatively short time using up-to-date topographical, hydrological and hydrographical information.</p><p>Authors have developed and tested methodological approach and GIS-tools for automated hydropower potential estimation. Re-estimation of hydropower potential was fulfilled by the authors for the most part of Russia. The data for more than 10 000 river’s was compared to the results of prior studies (data, such as river basin area, annual river flow, hydropower potential). The gross hydropower capacity of rivers and gross hydropower potential were estimated as 350 GW and  3,07*10<sup>3</sup> TWh respectively.</p><p>The next step in hydropower potential studies is prospective hydropower plants siting. Authors developed methodological approach and GIS-tools to automate this process. The GIS-tools provide comparison of site alternatives based on their hydropower parameters; transport, infrastructure, electricity network proximity; topographic situation and other factors affecting site suitability. Algorithm of automation and results of the search siting are presented.</p>

Wind energy has many advantages compared to traditional energies, from the ability to reduce the use of fossil fuels as well as the possibility of creating jobs in the areas where the projects are installed. The growth of this type of generation in Brazil has been driven by strong investor interest due to the characteristics of the country's winds, mainly from the Northeast. The winds are strong, stable and most of the time follow the same direction, characteristics that make windfarms in the Northeast region have high levels of capacity factor. By evaluating the data from the wind farms installed in Ceará, it can be observed that they present one of the best capacity factors in Brazil and have values above the world average. This indicates and reinforces the viability of implementing this type of energy generation in the area. It was verified that there are studies about wind conditions but there are no studies that correlate this information with the infrastructure conditions of the State. Therefore, the objective of the present work is to identify the appropriate areas for the allocation and use of wind energy in the State of Ceará through the integration of Geographic Information Systems (GIS) tools and multicriteria analysis for decision making.
