Book Description
LE PROCESSUS DE GENERALISATION PERMET DE DERIVER D'UN ENSEMBLE DE DONNEES INITIALES, L'INFORMATION NECESSAIRE ET SUFFISANTE POUR REALISER DES ANALYSES GEOGRAPHIQUES PARTICULIERES. CE PROCESSUS EST UTILISE DEPUIS LONGTEMPS PAR LES CARTOGRAPHES. L'OBJECTIF DE CETTE THESE EST DE PROPOSER UN MODELE PERMETTANT SON AUTOMATISATION A PARTIR DE DONNEES NUMERIQUES. NOTRE APPLICATION EST LA GENERALISATION DE DONNEES URBAINES POUR LA REALISATION D'UNE CARTE AU 1 : 50 000 SUR LE PROTOTYPE STRATEGE DEVELOPPE A CET USAGE. LE MODELE PROPOSE S'APPUIE SUR TROIS PRINCIPES : 1- L'AUTONOMIE DONNEE A L'INFORMATION POUR QU'ELLE SE GENERALISE, 2- LES CONTRAINTES POUR QUE CHAQUE SITUATION GEOGRAPHIQUE POSSEDE SES PROPRES OBJECTIFS QU'ELLE TENTE DE SATISFAIRE GRACE A SES ALGORITHMES DE GENERALISATION 3- L'EXISTENCE DE NIVEAUX D'ANALYSE MICRO, MESO ET MACRO QUI ONT DES ROLES DIFFERENTS DANS LE PROCESSUS. LES OBJETS MESO DECRIVENT DES GROUPES D'OBJETS. ILS PERMETTENT ENTRE AUTRE UN MEILLEUR MAINTIEN DES RELATIONS D'ORDRE, DE SIMILITUDE ET DE DIFFERENCE ENTRE LES CARACTERES D'UN GROUPE PAR DES ANALYSES DE DISTRIBUTION. AU NIVEAU D'UNE SITUATION, NOUS IDENTIFIONS LES CARACTERES PRINCIPAUX QUI SONT CONTRAINTS EN FONCTION DES SPECIFICATIONS DE GENERALISATION ET NOUS PROPOSONS DE CORRELER L'ETAT DES CONTRAINTES AUX ALGORITHMES QUI LES AMELIORENT. NOUS PROPOSONS EGALEMENT D'INTRODUIRE LES CONTRAINTES DANS LES ALGORITHMES AFIN MIEUX CONTROLER LEUR APPLICATION. LES MECANISMES DE CHOIX, DE VALIDATION, D'APPRENTISSAGE ET LES COMMUNICATIONS - UTILISEES POUR LA COORDINATION D'ACTION - SONT ETUDIES CAR ILS CONSTITUENT LA DYNAMIQUE DU SYSTEME PROPOSE. ENFIN, NOUS DECRIVONS LES ETAPES DU PROCESSUS GLOBAL COMPRENANT LA CONCEPTION D'UN SCHEMA ADAPTE, LA SAISIE DES SPECIFICATIONS ET L'OBTENTION DE DONNEES QUALIFIEES. CE MODELE APPORTE DES PRINCIPES QUI FONT EVOLUER LES SYSTEMES D'INFORMATION GEOGRAPHIQUE VERS DES SYSTEMES D'ANALYSE GEOGRAPHIQUE, QUI CORRESPONDENT AUX BESOINS ACTUELS

Book Description
The past 20 years can be regarded as the adolescence of geographic information science (GIS), as it grew from a burgeoning area of study into a mature and thriving field. During those two decades, the International Journal of Geographic Information Science (formerly Systems) (IJGIS) was one of the most prominent academic guiding forces in GIScience

Book Description
Geographic Information Systems are computer-based systems for geographic analysis. They have been developed over the past twenty five years and are now widely used. A recent research direction has been the development of geocomputation , representing computer-based geographical analysis beyond the traditional bounds of GIS. In geocomputation, the computer is the research environment itself, not merely a tool. A key to geocomputation it that highly powered computing can be used with sufficient data to avaid traditional parametric approaches altogether. The term geocomputation includes the use of computer-based techniques such as artificial neural networks, genetic programming and fuzzy logic, but in a geographical context. This new book in the prestigious Innovations in GIS series, presents the latest research in geocomputational techniques as presented in the GIS UK Annual Conference.

Book Description
Research in the field of automated generalisation has faced new challenges in recent years as a result of technological developments in web-based processing, new visualisation paradigms and access to very large volumes of multi-source data generated by sensors and humans. In these contexts, map generalisation needs to underpin ‘on-demand mapping’, a form of mapping that responds to individual user requirements in the thematic selection and visualisation of geographic information. It is this new impetus that drives the research of the ICA Commission on Generalisation and Multiple Representation (for example through its annual workshops, biannual tutorials and publications in international journals). This book has a coherent structure, each chapter focusing on core concepts and tasks in the map generalisation towards on-demand mapping. Each chapter presents a state-of-the-art review, together with case studies that illustrate the application of pertinent generalisation methodologies. The book addresses issues from data gathering to multi scaled outputs. Thus there are chapters devoted to defining user requirements in handling specifications, and in the application and evaluation of map generalisation algorithms. It explores the application of generalisation methodologies in the context of growing volumes of data and the increasing popularity of user generated content.

Book Description
This book, entitled Advances in Spatial Data Handling, is a compendium of papers resulting from the International Symposium on Spatial Data Handling (SDH), held in Ottawa, Canada, July 9-12, 2002. The SDH conference series has been organised as one of the main activities of the International Geographical Union (IGU) since it was first started in Zurich in 1984. In the late 1990’s the IGU Commission of Geographic Information Systems was discontinued and a study group was formed to succeed it in 1997. Much like the IGU Commission, the objectives of the Study Group are to create a network of people and research centres addressing geographical information science and to facilitate exchange of information. The International Symposium on Spatial Data Handling, which is the most important activity of the IGU Study Group, has, throughout its 18 year history been highly regarded as one of the most important GIS conferences in the world.

Book Description
The region of Central and Eastern Europe has a rich and long history in cart- raphy. Many important improvements in mapping and cartography have been proposed and performed by cartographers and researchers of that region. The long and outstanding history has led to a lively and vivid presence. Now contemporary methods for depicting the earth and its cultural and natural attributes are used. This book focuses on the contemporary activities in all major realms of cartography in Central and Eastern Europe. It covers aspects of theoretical, topographical, thematic and multimedia cartography, which have been presented at the frst Symposium on Cartography for Central and Eastern Europe, which took place from February 16th to 17th, 2009 in Vienna, Austria and was organized by the International Cartographic Association (ICA) and the Vienna University of Technology. The symposium’s aim was to bring together cartographers, GI scientists and those working in related disciplines from CEE with the goal of offering a platform for discussion and exchange and stimulation of joined projects. About 130 scientists from 19 countries followed the invitation and visited Vienna, Austria. A selection of fully reviewed contributions is edited in this book and is meant as a mirror of the wide range of activities in the realm of cartography in this region. The innovative and contemporary character of these topics has lead to a great variety of interdis- plinary contributions. Topics cover an enormous range with heterogenous relati- ships to the main book issues.
