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.

Manufacturing, storage, and transportation processes are typically facilitated by pallets, containers, and other reusable transport items (RTIs) designed to guarantee many cycles along a lifespan of several years. As a consequence, both supply and reverse transportation of RTIs need to be managed to avoid stockout along the supply chain and the unsustainable production of new tools from virgin materials. This paper focuses on the business of pallet management by analyzing the transport operations of a pallet pooling network serving a large-scale nationwide retailer. The pooler is responsible for supplying, collecting, and refurbishing pallets. The combination of the pooler’s management strategies with different retailer network configurations results in different pooling scenarios, which are assessed and compared in this paper through a what-if analysis. The logistical and environmental impacts generated by the pallet distribution activities are quantified per each scenario through a tailored software incorporating Geographic Information System (GIS) and routing functionalities. Findings from this analysis suggest how to reduce vehicle distance traveled (vehicles-km) by 65% and pollutant emissions by 60% by combining network infrastructures and pooling management strategies—identifying an empirical best practice for managers of pallet businesses.

Abstract. Debris flow, a very dangerous natural disaster, frequently occurs in mountainous areas of Sichuan province. China. Here, we applied the extenics method, which is normally used in single debris flow risk assessment, towards a large-scale debris flow risk assessment for the first time, and built the classical matter elements and joint domain matter elements for assessment of the debris flow risks in Sichuan province. Eight factors, including relative elevation, slope, rock hardness, rainfall, gully density, vegetation coverage, occurrences of historical debris flow and historical earthquake occurrences were selected for debris flow assessment by using geographic information system technology and weight analysis approach. Based on the risk assessment, the debris flow risk map was generated. Results indicate that areas with high risk and very high risk accounted for 21.32 % and 14.35 % of the whole province, respectively. 76 % of the verification points fall within the moderate, high and very high risk areas, suggesting high accuracy of extenics method in large-scale assessment areas. Thus, the Geographic Information System (GIS) and extenics based methods could provide a strong support for debris flow management in the region.
