A method for handling lightning-caused ignitions as part of a comprehensive fire hazard assessment procedure is presented. The locations at which lightning ignitions tend to occur have always been difficult to predict, and do not correlate with usual environmental factors. The model described here uses geographic information system techniques to remove large-scale trends in elevation. The meso-scale residual can be used to predict sites that are prone to lightning ignitions. The model is compared to historic records of lightning ignitions for the ACT, and is found to work very well. A range of other uses for the technique in fire management are discussed.

This paper was presented at the conference ‘Integrating spatial technologies and ecological principles for a new age in fire management’, Boise, Idaho, USA, June 1999 Fire modeling and information system technology play an important supporting role in fuel and fire management. Modeling is used to examine alternative fuel treatment options, project potential ecosystem changes, and assess risk to life and property. Models are also used to develop fire prescriptions, conduct prescribed fire operations, and predict fire behavior. Fire models and information systems have greatly influenced fuel assessment methods. As an example, we examine the evolution of technology used to put Rothermel’s fire spread model into application. A review of fire and fuel modeling terminology is given, and the relationship between fire models and fuel models is explained. We review current fire modeling work and the influence that it will have on fuel characterization. Finally, we discuss opportunities and challenges involved in the use of advanced computers, the Internet, Geographic Information Systems (GIS), and remote sensing in fire and fuel management.

This paper was presented at the conference ‘Integrating spatial technologies and ecological principles for a new age in fire management’, Boise, Idaho, USA, June 1999 ‘The earth, born in fire, baptized by lightning since before life"s beginning, has been and is a fire planet.’ E.V. Komarek Attitudes and policies concerning wildland fire, fire use, and fire management have changed greatly since early European settlers arrived in North America. Active suppression of wildfires accelerated early in the 20th Century, and areas burned dropped dramatically. In recent years, burned areas and cost of fires have begun to increase, in part due to fuel buildups resulting from fire suppression. The importance of fire as an ecosystem process is also being increasingly recognized. These factors are leading to changes in Federal agency fire and fuels management policies, including increased emphasis on use of prescribed fire and other treatments to reduce fuel loads and fire hazard. Changing fire management strategies have highlighted the need for better information and improved risk analysis techniques for setting regional and national priorities, and for monitoring and evaluating the ecological, economic, and social effects and tradeoffs of fuel management treatments and wildfires. The US Department of Interior and USDA Forest Service began the Joint Fire Science Program in 1998 to provide a sound scientific basis for implementing and evaluating fuel management activities. Development of remote sensing and GIS tools will play a key role in enabling land managers to evaluate hazards, monitor changes, and reduce risks to the environment and the public from wildland fires.

Building Information Modeling (BIM) is a technology that focusing on the building element properties to the construction components which cover the interior and exterior building, while Geographic Information System (GIS) describe to the technology that can provide the large-scale information which cover inside and outside buildings (spaces and areas). In construction project application, BIM technology already been used as a worldwide tool while GIS rarely been applied. Each technology contains their own advantages that can be utilized in the construction project application. To bring the best effective approach in construction project, the integration between BIM and GIS technology can be considered. This paper presented an attempt in integrating BIM and GIS by using FME as a data integration platform to solve the limitation of BIM in construction project by using advantages of GIS. Through this research, an investigation of the data exchange during integration process between BIM and GIS will be look up. By using this approach, it is possible to store the BIM and GIS data in one environment. The end results for this paper will cover the method of the data exchange between BIM to GIS and GIS to BIM. Besides that, this paper highlight how GIS can solve the limitation in BIM in construction project.

Many smaller pipeline operating companies see the benefits of implementing a Geographic Information System (GIS) to organize pipeline data and meet the requirements of 49 CFR 195, but cannot justify the cost of a large-scale AM/FM/GIS system. PPL Interstate Energy Company (PPL IE) is a pipeline company with 84 miles of main that implemented a GIS solution that leverages both existing technology and facility data investments. This paper discusses the process used to acquire landbase data, to organize existing pipeline data from a variety of paper-based and digital sources, and to integrate these data sets. It will also discuss the functionality and benefits of the resultant GIS.

Seepage velocity is a very important criterion in infrastructure construction. The planning of numerous large infrastructure projects requires the mapping of seepage velocity at a large scale. To date, however, no reliable approach exists to determine seepage velocity at such a scale. This paper presents a tool within ArcMap/Geographic Information System (GIS) software that can be used to map the seepage velocity at a large scale. The resultant maps include both direction and magnitude mapping of the seepage velocity. To verify the GIS tool, this study considered two types of aquifer conditions in two regions in Iraq: silty clayey (Babylon province) and sandy (Dibdibba in Karbala province). The results indicate that, for Babylon province, the groundwater flows from the northwest to southeast with a seepage velocity no more than 0.19 m/d; for the Dibdibba region, the groundwater flows from the west to the east with a seepage velocity not exceeding 0.27 m/d. The effectiveness of the presented tool in depicting the seepage velocity was thus demonstrated. The accuracy of the resultant maps depends on the resolution of the four essential maps (groundwater elevation head, effective porosity, saturated thickness, and transmissivity) and locations of wells that are used to collect the data.

When the European Union began to finance transport and pipeline infrastructure constructions in Bulgaria, large-scale development-led archaeological projects emerged. After 2011, many 'polluter pays' projects were executed with the outlined workflow containing preliminary reports and fieldwork activities in accordance with Bulgarian legislation and a defined price list. As part of the process the national 'sites and monuments' archaeological information system 'Archaeological Map of Bulgaria' (AIS AKB) plays an important part as a source of archaeological data for the territory of Bulgaria. This centralised structure controls the quality of the archaeological fieldwork and data standardisation. The aim is to transform the 'sites and monuments' information system to an archaeological geographic information system (GIS) based on geospatial features, largely using an accumulation of standardised data.

In recent years, many countries have faced great challenges due to their limited water resources. According to these challenges, they have undertaken large scale projects to reuse agricultural drainage water in irrigation purpose. The Governments in these countries can enhance water management and sustainable development by adopting policies that enable them to meet water demands and supply management. Therefore, there is a need for unconventional methods to provide better tools for the assessment and management of water quality problems to adopt management policies and set the limits for sustainable drainage water reuse. The implementation of Geographic Information System (GIS) in this field offers an ideal tool for measurements with limited number of sampled points. Statistical analysis that can be provided within GIS is rapidly becoming an impressive tool for statistical analysis of continuous data. The main objective of this chapter is to discuss using GIS to in-follow the pollution caused by fertilizers migration to the water and the soil by applying statistical analysis within the GIS using geostatistical analyst. Geostatistical analyst is an extension of Arc Map™ that bridges the gap between geostatistics and GIS and provides a powerful collection of tools for the management and visualization of spatial data by applying Spatial Statistics.

A expansão de áreas agrícolas e urbanas, a implementação de projetos industriais, entre outras atividades antrópicas, promovem a alteração da paisagem original, criando outra, dominada por vários remanescentes da vegetação nativa. Estes remanescentes, denominados também de fragmentos florestais, são fundamentais para manutenção da biodiversidade existente no local. Porém uma paisagem fragmentada torna os remanescentes florestais isolados vulneráveis, nesse sentido, torna-se importante a concepção de conexões para interligar os fragmentos, diminuindo a pressão sobre sua diversidade e aumentando o fluxo de espécies, o fluxo gênico e a quantidade e qualidade dos hábitats existentes. Uma das formas de interconexão possíveis é a criação de corredores ecológicos, interligando os fragmentos, portanto, este estudo tem como objetivo indicar áreas para o estabelecimento de corredores ecológicos, por meio de um Sistema de Informações Geográficas (SIG), segundo critérios relacionados ao uso e ocupação do solo na Zona de Preservação Ecológica do Complexo Industrial Portuário Eraldo Gueiros - Suape (CIPS). Para tanto, foram utilizados atributos ambientais (variáveis), aos quais foram atribuídos pesos matemáticos e analisados por meio de geoprocessamento. Os resultados encontrados nesse estudo denotam a importância do uso do SIG como uma importante ferramenta para análise de áreas em grande escala, as áreas recomendadas para a implementação de corredores por meio da análise de geoprocessamento foram compatíveis com análises realizadas na paisagem, sendo que os pesos dados as variáveis foram eficientes em agrupar os atributos biológicos, físicos e antrópicos, resultando em conexões possíveis de serem realizadas em campo.    A B S T R A C T The expansion of agricultural and urban areas, the implementation of industrial projects, among other human activities promote the alteration of the original landscape and creates another dominated by several remnants of native vegetation. These remnants, also called forest fragments are essential to maintain local biodiversity. But the isolated forest remnants in a fragmented landscape become vulnerable. Thus the design of connections for linking the fragments becomes important to reduce the pressure on its diversity and increase the flow of species, gene flow and the quantity and quality of existing habitats. One way of interconnection possible is the creation of ecological corridors, linking the fragments. Therefore this study aims to indicate areas to the establishment of ecological corridors through a Geographic Information System (GIS), following criteria related to the use and occupation of soil of Ecological Preservation Zone in Complexo Industrial Portuário Eraldo Gueiros - Suape (CIPS). To this end, we used environmental attributes (variables) that have been assigned mathematical weights and analyzed using geoprocessing. The result in this study show the importance of using GIS as an important tool for analyzing large-scale areas. The areas recommended for implementation of corridors through the analysis of GIS were consistent with analysis undertaken in the landscape with the weights data variables were efficient to group biological, physical and antropic attributes, resulting in connections that can be developed in the field.
