GIS applied to administrative boundary design

Eagleson, Serryn January 2003 (has links) (PDF)
The fragmentation of administrative boundaries is a serious problem in the analysis of social, environmental and economic data. This research focuses on the development of a coordinated approach to the design of administrative boundaries that endeavours to support accurate decision making. Around the world, administrative boundaries have been structured in an uncoordinated manner, limiting data exchange and integration between organisations. The solution proposed in this research adopts the hierarchical reorganisation of administrative boundaries to enhance data integration and data exchange within the spatial data infrastructure (SDI) framework.The SDI is an initiative intended to facilitate access to complete and consistent data sets. One of the most fundamental problems restricting the objectives of the SDI is the fragmentation of data between non-coterminous boundary systems. The majority of administrative boundaries have been constructed by individual agencies to meet individual needs. Examples of the proliferation of different boundary systems include postcodes, census-collector districts, health districts and police districts. Due to the lack of coordination between boundary systems, current technologies for analysing spatial data, such as geographic information systems (GIS), are not reaching their full potential. A review of the current literature reveals that, until now, little has been done to solve this problem.The prototype developed within this research provides a new mechanism for the design of administrative boundaries. The prototype incorporates two algorithms. These are based on HSR theory and administrative-agency constraints and are implemented within the GIS environment. Such an approach is an example of the potential that is available when we link spatial information theory with the SDI framework and disciplinary knowledge.

Cooperation between high-speed rail and air travel in the United States

Suski, Shea Matthew 13 July 2011 (has links)
The United States as a whole is embarking on the historic task of implementing high-speed rail (HSR) throughout the country in an attempt to improve regional mobility, including congestion at some of the nation’s busiest airports. However, despite the wide overlapping of service that both air and HSR provide and the goal of reducing airport congestion, little discourse has occurred on the topic of how these two modes might interact in an intermodal context. This report explores how air travel and HSR might cooperate in the US, which is defined as an explicit attempt by the two modes to utilize each other in order to transport a passenger to their final destination. It will document potential benefits of cooperation, survey how cooperation works elsewhere in the world, and investigate the current climate within the US for cooperation, including a review of current HSR plans and analysis of air travel data. This information will form the basis for suggested airports for the integration of HSR and air travel, and for how US airlines might utilize HSR. Lastly, lessons learned will form a list of best practices to follow in order to better insure a cooperative and successful relationship between HSR and air travel. / text

Exploitation de séries temporelles d'images satellites à haute résolution spatiale pour le suivi des prairies en milieu agricole / Use of time–series of high spatial resolution satellite images for grassland monitoring in agricultural areas

Dusseux, Pauline 05 December 2014 (has links)
En milieu agricole, on observe depuis plusieurs décennies une régression des prairies ainsi qu’uneévolution de leur mode de gestion liées à l’intensification de l’agriculture. Face aux enjeux que ces changementsimpliquent tant sur le plan environnemental qu’économique, l’estimation de la place des prairies dans les systèmes de production et la détermination des pratiques agricoles qui leur sont associées sont stratégiques. Avec l’arrivée de nouveaux capteurs de télédétection à Haute Résolution Spatiale (HRS) caractérisés par une résolution temporelle élevée, il est désormais possible d’envisager l’étude des couverts prairiaux à une échelle fine et à partir d’observations régulières dans le temps. L’objectif de cette thèse est d’identifier les couverts prairiaux à l’échelle des territoires agricoles et de déterminer leurs modes de gestion à partir de paramètres dérivés de séries temporelles d’images de télédétection à HRS. Pour cela, plusieurs séries intra–annuelles d’images à haute résolution spatiale optiques et radars ont été constituées afin de recenser les prairies et d’identifier trois de leurs modes de gestion : le pâturage, la fauche et l’exploitation mixte, sur un bassin versant dont le système d’exploitation dominant est l’élevage laitier. Les résultats obtenus à partir du traitement et de l’analyse des séries temporelles optiques ont permis de montrer qu’il est possible d’estimer avec une bonne précision la biomasse des prairies, de les identifier et de les caractériser. Ils mettent aussi en évidence le fait que les images radars améliorent l’identification des prairies sans pouvoir discriminer leurs modes de gestion, l’utilisation combinée des deux types d’images augmentant encore le taux d’identification des prairies. Par ailleurs, les résultats montrent que les méthodes de classification s’appuyant sur des critères de comparaison adaptés aux séries temporelles (distances élastiques) produisent des résultats nettement plus satisfaisants pour discriminer les modes de gestion des prairies que les méthodes de classification standards. / In agricultural areas, we observed a decrease of grasslands and change in their management in the last half–century, which are commonly associated with agriculture intensification. These changes have affected environmental and economic systems. In this context, the evaluation of grassland status and grassland management in farming systems is a key–issue for sustainable agriculture. With the arrival of new Earth observation sensors with high spatial and temporal resolutions, it is now possible to study grasslands at fine scale using regular observations over time. The objective of this thesis is to identify grasslands and their management practices using parameters derived from time–series of high spatial resolution (HSR) remote sensing data. For that purpose, several intra–annual time series of HSR optical and Synthetic Aperture Radar (SAR) satellite images were acquired in order to identify grasslands and three of their management practices: grazing, mowing and mixed management, on a catchment area mainly oriented towards cattle production. Results obtained from the processing and analysis of the optical time series have shown that it is possible to estimate with good accuracy grassland biomass, to identify and to characterize them. They also highlighted that radar images improve grassland identification without being able to distinguish management practices, the combined use of the two types of images further increasing grassland identification. Furthermore, results showed that the classification methods based on comparison criteria adapted to time series (warping criteria) increase significantly results for discriminating grassland management practices compared to standard classification methods

Extern belastning hos elitfotbollsspelare – en litteraturöversikt på kvinnliga spelare. : En studie om total distans i olika hastigheter, acceleration, deceleration samt topphastighet under matchspel inom kvinnlig elitfotboll.

Shojaeddin, Hossein, Pacha, Kevin January 2023 (has links)
Den kvinnliga fotbollen har aldrig varit lika populär som den är idag och den fortsättergöra framsteg och lockar mer publik, samtidigt som flera tjejer/kvinnor börjar utövasporten. Tidigare forskning är begränsad gällande kvinnliga elitfotbollsspelare, merforskning inom kvinnlig fotboll och dess externa belastning kan hjälpa den kvinnligafotbollens utveckling. Kraven som ställs skiljer sig efter den position spelaren har, denexterna belastningen är en viktig del inom fotbollen. Fotbollen ställer krav på löpningari olika riktningar och i olika hastigheter, inbromsningar samt acceleration. Varjeposition tillämpar olika egenskaper. Syftet var att sammanställa kunskapen gällande denexterna belastningen hos kvinnliga elitfotbollsspelare. En systematisk deskriptivlitteraturöversikt med en systematisk sökning har använts för att besvara studiens syfte.Sökningen gjordes i databaserna Discovery och Pubmed och resulterade i 10vetenskapliga artiklar. En kvalitetsanalys utfördes på artiklarna, med hjälp av SBUmallar bedömdes 10 artiklar med poäng, av dessa 10 fick 4 artiklar 4 poäng, 1 fick 5poäng, 4 fick 6 poäng och 1 fick 7 poäng. Resultatet delades in i 3 teman: total distans iolika hastigheter, acceleration och deceleration samt topphastighet. De förstnämnda ochsistnämnda innebar att det skiljde sig beroende på position medan acceleration ochdeceleration syftade på hur många gånger det sker under en match men även om vilkazoner det sker i. Det ställs olika krav på spelarna beroende på position. De sekvensersom sker under en fotbollsmatch påverkas utifrån den position som spelaren har.Resultatet visade att kvinnliga elitfotbollsspelare har en totaldistans mellan 10–12 kmper match, utför mellan 400–1000 accelerationer och decelerationer och har engenomsnittlig topphastighet på ca 26 km/h. Sammanfattningsvis visar studien att denexterna belastningen som ställs på kvinnliga elitfotbollsspelare handlar om vilkenposition spelaren har. Resultatet ger även möjligheten för tränare att förbereda spelarnabättre inför match genom att anpassa träningsupplägget
