The Uk

In 1985, the UK government set up a Committee of Enquiry into the Handling of Geographic Information by computer. This was chaired by Lord Chorley and reported in early 1987. It concerned itself with all information which is described in relation to space and which could hence be used either singly or in combination. The tasks undertaken by the Committee are described, as are its composition and method of operation, the major ‘discoveries’ it made, and the recommendations put forward to government. A total of sixty-four recommendations were made covering digital (especially Ordnance Survey) topographic mapping, the availability of geographically disaggregated data, the problems and benefits of linking different data sets together, the need to enhance user awareness of geographical information systems and information technology, education and training, research and development, and the appropriate role for government and machinery for coordination. Finally, the government's published response to the Chorley Report is examined, particularly with regard to the proposed Centre for Geographic Information. The subsequent moves towards a consortium to bring this about are described.

Radical Transformation

Maps and mapping are the manifestation of geography for the great bulk of the population. These play a key role in society and underpin many functions of the state. The situation is particularly marked in Britain, both in war and peace, where the Ordnance Survey (the country's national mapping agency) has been central to national mapping for more than two centuries. It is no exaggeration to say that mapping underpins many of the activities of society, especially in Britain. The collation, visualisation and analysis of geographical information through maps are intimately intertwined. Since British geography and British geographers have been involved in all aspects of mapping and its successor, this chapter covers both academic and non-academic aspects of the subject area. This chapter examines the geographical underpinning of British society and its radical transformation, Geographical Information Systems and information technology and non-trivial cartography.

Accessibility measures are generally concerned with equity and a better distribution of services in a territory and can be accepted as key variables for supporting supply/demand, location/allocation and service/catchment area related planning policies and strategies at national, regional, and local levels. Since accessibility measures need organization of huge and complex spatial data sets, accessibility modeling often lends itself to Geographical Information Systems (GIS) for analysis and presentation. Since numerous accessibility measures and modeling techniques ranging from simple to sophisticated can be found in the literature, this work aim to provide an overview of the theoretical framework and relevant background about GIS-based accessibility modeling process. The results could provide a significant support for the decision makers who are supposed to deal with transportation planning, accessibility modeling, location/allocation and service/catchment area related issues.

O meio ambiente e todos os aspectos relacionados ao seu uso, conservação e proteção estão sendo cada vez mais objeto de discussão. Para que a gestão pública obtenha bons resultados na proteção de recursos naturais, é fundamental o uso de tecnologias associadas à administração. Os Sistemas de Informações Geográficas (SIGs) possibilitam integrar bases de dados administrativos de municípios a bases cartográficas, permitindo maior agilidade na tomada de decisões a preservação de recursos. As múltiplas análises passíveis de execução em um SIG levam, em conjunto, a melhor gestão de uma grande massa de dados. Com tal visão, foi desenvolvido o projeto de extensão “SIG e Gestão Pública: Interação Universidade-Administração” do qual foram apresentadas aqui algumas experiências vivenciadas durante seu período de execução (2016-2017). Os objetivos do projeto foram: capacitar gestores públicos (prioritariamente), estudantes universitários e população em geral quanto à aplicação do SIG (SPRING); promover a troca de experiências das diferentes aplicações do Software na administração pública; assessorar gestores públicos na tomada de decisões, e incentivar a disponibilização de dados e resultados técnicos para novos estudos. As atividades presenciais foram realizadas nas dependências do Campus Central da UNESP de Ilha Solteira/SP e incluíram workshops e exercícios práticos com SIG. Merecem destaque a assiduidade e a avaliação final positiva dos participantes (em 2016 e 2017), as iniciativas de trocas de experiências entre eles, e a busca por novas soluções de obtenção e tratamento de dados e seu compartilhamento. As trocas de experiências e a busca por novas soluções foram as razões de maior interação entre os cursistas, e entre eles e a equipe que desenvolveu o curso.

To achieve good results in public management of natural resources, the use of technologies associated with the administration is essential. Geographic Information Systems (GIS) make it possible to integrate administrative databases of municipalities to cartographic databases, allowing greater flexibility in decision-making resource conservation. The multiple analyzes that can be executed in a GIS lead, together, the best management for a large amount of data. With this in mind, was developed the extension project "GIS and Public Management: University-Administration Interaction", which are presented here some experiences during its execution period (2016-2017). The objectives of the project were: to train public managers (primarily), University's students and the average population about the application of GIS (SPRING); to promote the exchange of experiences of different applications of the Software in the public administration; advise public managers on decision making and encourage the provision of data and technical results for further studies. The classroom activities were held on the premises of the UNESP Campus at Ilha Solteira - SP and included workshops and practical exercises with GIS. It is worth noting the assiduity and the positive final evaluation of all participants (in 2016 and 2017), the will to exchange experiences and the search for new ways of data acquisition and processing solutions, as well as sharing it. The experience exchange and the search for new solutions were the most critical factors in the interaction between the students and the team that developed the course.

Set Up

Cameroon through its Strategy for Growth and Employment (DSCE), has set up the construction of the Yaoundé-Nsimalen highway project. As part of the assessments of its potential effects on the environment, an ESIA was carried out, according to the framework law on the management of the environment. The acquisition of housing has resulted in an '' anarchic '' installation in the urban and peri-urban area. The construction of a highway as planned overlays on these facilities and poses a problem related to the liberation of spaces previously occupied. The purpose of this study is to identify, locate and classify the impacted goods by the highway construction project through Geographic Information Systems (GIS). Our methodology consisted first, making a satellite identification of the impacted goods, then a field campaign and finally a processing of the data collected. This study was also limited to the identification of two types of property, the buildings and parcels of land. Thus, it has been possible to distinguish and locate six categories of buildings, eight categories of parcels of land defined according to the Cameroon law No. 85/009 of 04 July 1985 on the expropriation for public purpose and the terms of compensation and according to Order No. 0082 / y. 15.1 / MNUH / D of November 20, 1987 laying down the bases for calculating the market value of buildings expropriated for reasons of public utility. The result of this study shows that mapping is a very practical tool for identifying and materializing the impacts that a project may have on components of environment. The GIS revealed a potential disappearance of 1502 building spread over 867 parcels of land.

Geographical Information

Geographical Information Systems (GIS) are considered to be applications-led technology. Consequently, geographic information scientists commonly find themselves as guest in host disciplines in order to best exploit spatial analysis tools and methods, appropriately guided by experts in the field. An example is population genetics in evolutionary biology. Genetic information being linked to living organisms can be partially characterized by geographic coordinates. A research field named landscape genetics emerged at the intersection of genetics, environmental and geographic information science. Geocomputation and programming efforts carried out with the help of open sources technologies and dedicated to the analysis of genetic data gather together a key scientific community whose goal is to extract new knowledge from the present data tsunami caused by the advent of high throughput molecular data and of new sources of high resolution environmental data. While the level of sophistication of the population genetics functions included in the analytical frameworks developed until now are cutting-edge, advanced geo-competences are also required to reinforce the spatial side of this discipline. They will be particularly useful in conservation programmes for wildlife preservation, but also in farm animal genetic resources conservation.

The City

Hurricanes affect thousands of people annually, with devastating consequences such as loss of life, vegetation and infrastructure. Vegetation losses such as downed trees and infrastructure disruptions such as toppled power lines often lead to roadway closures. These disruptions can be life threatening for the victims. Emergency officials, therefore, have been trying to find ways to alleviate such problems by identifying those locations that pose high risk in the aftermath of hurricanes. This paper proposes an integrated methodology that utilizes both Google Earth Engine (GEE) and geographical information systems (GIS). First, GEE is used to access Sentinel-2 satellite images and calculate the Normalized Difference Vegetation Index (NDVI) to investigate the vegetation change as a result of Hurricane Michael in the City of Tallahassee. Second, through the use of ArcGIS, data on wind speed, debris, roadway density and demographics are incorporated into the methodology in addition to the NDVI indices to assess the overall impact of the hurricane. As a result, city-wide hurricane impact maps are created using weighted indices created based on all these data sets. Findings indicate that the northeast side of the city was the worst affected because of the hurricane. This is a region where more seniors live, and such disruptions can lead to dramatic consequences because of the fragility of these seniors. Officials can pinpoint the identified critical locations for future improvements such as roadway geometry modification and landscaping justification.

Spatio Temporal

This paper is composed of two parts dealing with the modeling of environmental phenomena. The first part presents the traditional ER and OO formalisms dedicated to geographic information modeling. These languages focus mainly on representing the spatial and temporal properties of this type of information. Many of these languages express these properties visually by using pictograms. After a quick historical presentation of the languages, the authors show the various types of spatiality and temporality usually encountered in these languages. Often qualified as primitive, some of these spatialities and temporalities are simple. Others, which are more complex, result from combinations of simple spatialities and simple temporalities. Still others are used in very specific situations encountered during the development of geographical information systems. These different spatialities and temporalities are presented via examples provided in the field of environmental dynamics.
