Abstract:
Making smart and informed decisions often requires the integration and analysis of large amounts of data. However, integrating these data is rarely straightforward, mainly because of heterogeneities in data structure and format. In this study, we focus on two widely used data formats by municipalities to store digital maps of their infrastructure: Computer-Aided Design (CAD) and Geographic Information Systems (GIS). While most municipalities still maintain infrastructure data in CAD format, many have started converting them to GIS since GIS includes geographical coordinates. However, the inherent differences between these two formats pose challenges to accurately converting information from CAD to GIS. The main goal of this study is to develop a procedure to help municipalities to perform CAD-to-GIS conversion. To that end, potential problems in CAD-to-GIS conversion were first identified through interviews with practitioners at different U.S. municipalities and through a literature review. Taken together, we propose the C2G framework to streamline the conversion process while minimizing information loss. The framework consists of five stages, and the execution of this framework and tasks involved in each stage are explained. Moreover, we apply the framework to real-world underground stormwater infrastructure data obtained from the University of Illinois at Chicago (UIC) to illustrate the framework’s applicability. The case study explains details about the technical difficulties we encountered in the process and provides recommendations to circumvent those difficulties. The results from the case study showed that the C2G framework was able to successfully convert CAD data to GIS data. Although the framework is developed specific to the needs of CAD/GIS practitioners in the US municipalities, it can be adopted in most CAD-to-GIS conversion situations. The information learned during the interviews supports the need for a standard CAD-to-GIS conversion process. The contribution of this study is to fill this gap by developing a generalized framework to carry out CAD-to-GIS conversion which only requires basic knowledge of CAD and GIS.

Abstract:
The paper deals with current issues of spatial data modelling and management used by spatial management applications. As a case study for explaining the problem, we use comparison of two main groups of software tools covering this area GIS and CAD systems - and the posibilities of their integration. Studying its functionality, we have found two main problematic issues. The first of them is the density distribution characteristics of stored data according to described area. CAD systems are oriented towards modeling individual man-made objects and structures with relatively high level of detail, so the data stored covers small areas with huge amount of information. On the other side GIS applications maintain large-scale models of real world with significantly lower amount of detail. Here the density distribution of data coverage is better balanced. So the combination of described different densities is the first problem. The second watched issue is the way of storing spatial data. While CAD data are usually stored in individual files (like DXF, IGES), GIS data tend to be stored in files or realtional databases. The question we see is, if it is possible to store CAD data along with GIS data in the same database in spite of different distribution densities and different data models. Our paper describes ways of solving this problem.

Abstract:
Texas is botanically diverse with approximately 5500 native plants identified: east Texas contains about 40% of the total. While most species are stable, many are classified as rare, threatened, vulnerable, or endangered. Databases for east Texas plant communities and vegetative analyses are numerous. However, they are not yet integrated into easy-to-sort-and-query computer files. Computer-Assisted Drafting (CAD) and Geographic Information Systems (GIS) technology offers powerful applications to the storage, management, and spatial analysis of species inventories, plant community dynamics, and long-term habitat monitoring. At SFASU, the College of Forestry's GIS Center is being utilized to develop comprehensive east Texas resource inventories on a ten-station HP Apollo/ArcInfo platform. In the horticulture program, a twenty-station PC/AutoCad teaching laboratory is being used to create layered maps of the SFASU Arboretum, the on-campus landscape and off-campus plant communities. The integration of CAD and GIS projects through a DXF format takes advantage of the attributes of both technologies.

Abstract:
AutoCAD is an accessorial desktop cartography software widely used in project cartography for its easy manipulation and data edit ability. GIS is a powerful tool of using computers to make dimensional with advantage of display, analysis, output and management of geographical data. The data of the two systems is not compatible and they need to be transformed for data sharing and application. This paper points out the difference of AutoCAD and GIS data, analyzes some common problems during the data transforming process and introduced the experimental study which takes example for transforming the CAD forestry map of Buyunshan country, Dalian city to ArcView geographical information system. The objective of this paper was trying to find an effective way for the transformation from CAD graphics files to geographical information system.

Abstract:
As staff and budgets shrink and environmental requirements grow, facilities managers face a critical need for more timely access to geographic-based information to achieve regulatory compliance. An integrated Geographic Information System (GIS) can successfully satisfy this need for a large municipality. But for managers at smaller facilities, a full-function GIS often exceeds what is needed and affordable. Such managers can derive similar benefits with minimal staff, budget, and equipment investments by developing a microcomputerbased system, using CAD/CAM software as a mapping package linked with third-party database management software. This paper describes how a military installation in Hawai'i successfully built such a system using AutoCAD and dBase III+.

Abstract:
3D city models are important in urban planning for sustainable development. Usually and traditionally, urban planners design the future layout of the towns by drawing the maps, using GIS or CAD packages. 3D city models based on these maps are quite effective in understanding what if the plan is realized. However, creating 3D city models is labor intensive, using a 3D modeling software such as 3ds Max or SketchUp. In order to automate laborious steps, we are proposing a GIS and CG integrated system for automatically generating 3D building models with general shaped roofs by straight skeleton computation, based on general shaped building polygons (building footprints) on digital maps.

Abstract:
GIS is a spatial information system combining geography, cartography, remote sensing and computer science, which is widely used in different fields. As a computer system, GIS can input, store, query, analyze and display geographic data. In the 1980s, GIS gradually began to be applied in the field of urban planning. This kind of digital technology meets people's requirement for regional geographic environment visualization. At the same time, the development of the network has also provided help for the popularization and development of this technology, making the dissemination and sharing of data possible. Nowadays, as an important technology, GIS has been widely used in all fields of urban planning and has gradually become an indispensable part. Arcgis as GIS platform building and applications will be treated as big data analysis and data visualization as an important part of planning, implementation of the software data correlation of traditional urban planning, break traditional design and drawing mode, through the spatial analysis function to generate new information, make decisions and solve problems efficiently, and make a prediction to the development of future city. Through the introduction of Arcgis data organization structure, CAD data loading, mapping and modeling under Arcgis platform and Arcgis spatial analysis function, this paper discusses how to use Arcgis platform to realize the application of urban planning and design.

Abstract:
With the drive to continually reduce the cost of connecting new Coal Seam Gas (CSG) wells, Worley developed new methodologies using commercial off-the-shelf software, and custom development, to automate engineering and improve operational efficiency for pipelines and gathering systems. One of the recent developments is an automated and data-driven approach to produce Gathering Network Diagrams (GNDs), an alternative to conventional Piping & Instrumentation Diagrams (P&IDs). On a recent project, Worley implemented a GND workflow capable of showing ~40 wells per A3 deliverable in conformance with intelligent drafting standards. This reduced ~2000 as-built P&IDs to ~200 GNDs (and associated standard details) with a significant improvement in quality and usability. Prior to generation, a site walkdown was conducted to address mismatches between as-built P&IDs, Geographic Information System (GIS) and what was actually installed at site. Our client now has a suite of GNDs that match the installed asset and are produced from the corporate GIS database, essentially their Digital Twin. Worley then focused on integrating flow assurance software with GIS allowing data-driven execution of future design packages to be incorporated into the master GNDs. We successfully integrated with PipeSIM and GAP, allowing for seamless transfer of hydraulic inputs from GIS to the modelling software. Engineers can now synchronise the confirmed process design back to GIS without producing red-lined and/or CAD-drafted deliverables which greatly improves efficiency and reduces human error. This paper demonstrates how digital automation can be applied to the CSG industry to significantly reduce cost and schedule whilst enabling data-driven operational efficiencies.

This chapter underlines the necessity of establishing a carefully thought-out method to answer precise questions. We will also use this opportunity to discuss the possibilities and difficulties generated by the use of computers to record and process data from archaeological excavations. Which reflections lead the archaeologist to use a particular tool? The amount of data-processing software for the treatment of various types of information (word processing, spreadcards, CAD, data bases, GIS, etc.) is continuously growing and developing. While it is obvious that the use of certain software facilitates the analysis of archaeological data (up to the point where it becomes essential to the archaeologist), is it also necessary to constantly adapt archaeological data processing methods to the use of new software?

Abstract:
Spatial data management has been an active area of intensive research for more than two decades. In order to support spatial objects in a database system several important issues must be taken into account such as: spatial data models, indexing mechanisms and efficient query processing. A spatial database system (SDBS) is a database system that offers spatial data types in its data model and query language and supports spatial data types in its implementation, providing at least spatial indexing and efficient spatial query processing (Güting, 1994). The main reason that has caused the active study of spatial database management systems (SDBMS) comes from the needs of the existing applications such as geographical information systems (GIS), computer-aided design (CAD), very large scale integration design (VLSI), multimedia information systems (MIS), data warehousing, multi-criteria decision making, location-based services, etc.

Abstract:
Since spatial decision processes have to deal with large number of actors, opinions and interests, literature commonly agrees in recognising data sharing and communication as essential in achieving decisional tasks (Van den Brink et al., 2007; MacEachren et al., 2004). The following chapter describes a methodological instrument for managing data, namely the Interactive Visualisation Tool (InViTo). InViTo aims at supporting spatial decision-making processes by proposing a framework for data knowledge. Principally based on Grasshopper, a free plug-in for McNeel's Rhinoceros, InViTo combines GIS data with CAD drawings and raster images for generating interactive spatial visualisations. It is conceived to display in real time the relationships between the territory and planning choices; thus, it is particularly indicated for stimulating discussions and sharing information in collaborative processes. Its high flexibility allows its use in different case studies with a variety of purposes and scales. Innovative elements in approaching spatial decision processes are discussed.

Abstract:
In spite of the fact that relational databases still hold the first place in the market, object-oriented databases are becoming, each day, more widely accepted. Relational databases are suitable for traditional applications supporting management tasks such as payroll or library management. Recently, as a result of hardware improvements, more sophisticated applications have emerged. Engineering applications, such as CAD/CAM (Computer Aided Design/ Computer Aided Manufacturing), CASE (Computer Aided Software Engineering) or CIM (Computer Integrating Manufacturing), office automation systems, multimedia systems such as GIS (Geographic Information Systems) or medical information systems, can be characterized as consisting of complex objects related by complex interrelationships. Representing such objects and relationships in the relational model implies that the objects must be decomposed into a large number of tuples. Thus, a considerable number of joins is necessary to retrieve an object and, when tables are too deeply nested, performance is dramatically reduced (Bertino and Marcos, 2000).

Abstract:
Information technologies (ITs) entered and irreversibly changed the discipline of archaeology during the last 20 years of the second millennium. The first experiments involved databases and alphanumeric data processing, then in the late 1980s GPS technologies, associated with spatial data processing, were first tested to locate archaeological objects in the geographical space. Computer-aided design (CAD) software has progressively replaced the traditional procedures of topographical and architectural design, while “New Archaeology” and “Processual Archaeology” focusing their attention on the quantitative aspects of phenomena (Binford, 1989; Binford & Binford, 1968; Clarke, 1968; Clarke, 1977) adopted “spatial technologies”, consisting of computer-based applications concerned with the acquisition, storage and manipulation of spatial information (Wheatley & Gillings, 2002).

Abstract:
Computer hardware and software have played a significant role in supporting the design and maintenance of pipeline systems. CAD systems allowed designers and drafters to compile drawings and make edits at a pace unmatched by manual pen drawings. Although CAD continues to provide the environment for a lot of pipeline design, Geographic Information Systems (GIS) are also innovating pipeline design through routines such as automated alignment sheet generation. What we have seen over the past two or three decades is an evolution in how we manage the data and information required for decision making in pipeline design and system operation. CAD provided designers and engineers a rapid electronic method for capturing information in a drawing, editing it, and sharing it. As the amount of digital data available to users grows rapidly, CAD has been unable to adequately exploit data’s abundance and managing change in a CAD environment is cumbersome. GIS and spatial data management have proven to be the next evolution in situations where engineering, integrity, environmental, and other spatial data sets dominate the information required for design and operational decision making. It is conceivable that GIS too will crumble under the weight of its own data usage as centralized databases become larger and larger. The Geoweb is likely to emerge as the geospatial world’s evolution. The Geoweb implies the merging of spatial information with the abstract information that currently dominates the Internet. This paper and presentation will discuss this fascinating innovation, it’s force as a disruptive technology, and oil and gas applications.

Abstract:
Abstract The use of Geographic Information System (GIS) in managing pipeline database and automating routine engineering processes has become a standard practice in the pipeline industry. While maintaining a central database provides security, integrity, and easy management of data throughout the pipeline’s lifecycle, GIS enables spatial analysis of pipeline data in addition to streamlining access and visualization of results. One of the major benefits of GIS integration lies in the ease of automating the alignment sheet generation for pipelines. This paper introduces a simplified pipeline alignment sheet generation workflow using GIS datasets to produce highly customizable alignment sheets in AutoCAD, a much-preferred format in the pipeline industry. By utilizing existing GIS and AutoCAD features to generate the alignment sheet, writing complicated geo-processing or plotting algorithms is minimized, which in turn reduces the risks of committing any systematic errors. This robust and user-friendly workflow not only ensures safety but also leads to a cost-effective solution.

Abstract:
We are on the edge of a revolution in the way we visualize and query digital data about our environment. To date, computer displays of our environment in the third dimension have been limited to computer-aided design (CAD) packages and the query of related data limited to geographical information systems (GIS) packages in two dimensions. The current innovation wave across the spatial data information field is based on the development and dissemination of three-dimensional GIS (3-D GIS) which allows data to be visualized and queried on an x, y and z axis plane. A number of the key players in information visualization allow conventional two-dimensional data to be viewed and exported in a three-dimensional format, currently using the standard Virtual Reality Modeling Language 2.0 (VRML 2.0). However such methods of visualization and data query are limited in their practicality. The move towards 3-D GIS in standard packages has been rather hit and miss, with the third dimension often only used as a substitute for basic CAD-like visualization. We argue here that 3-D GIS will only become a reality when it is directly linked with CAD models; and that the Internet is the most appropriate medium through which this is most likely to occur. We illustrate these arguments in an overview of research into the virtual city in general and our own development of ‘Virtual London’ in particular. Further, we explore the rise of the global virtual city, a network of virtual cities that provide an insight into the future of digital space.

Abstract:
Today’s tools and technologies allow the pipeline industry to collect information and describe company pipeline assets in a productive way. Rooney Engineering, Inc. recently completed a 130-mile crude oil pipeline in the greater Los Angeles area of California with which wide ranges of technologies were utilized over an 8-year period. Review of all phases of this pipeline project offers a unique glimpse of managing and integrating traditional survey and Global Positioning System (GPS) techniques with a Geographic Information System (GIS). While the first portion of the project used traditional methods of photogrammetry and Computer Aided Drafting (CAD) to complete the conceptual design and construction drawings, the second portion utilized a combination of CAD, GIS and GPS technologies to assist the construction team during construction and as-built. Geographically organized data was later applied beyond the phases of pipeline construction; data was later used in one-call, contingency planning and emergency response. This paper will give an overview of the project, including pre-construction drawing preparation, construction zones, terrain types, political jurisdictions, and original staff assignments for data collection. The paper will discuss data dictionary design and management of collected field data, equipment and personnel requirements, and accuracy trade-off. The paper will examine the verification of data for attribute integrity and assignment of positional accuracy tags, along with specific methods of GPS and traditional data collection, while also exploring data management of incoming field data from multiple sources over an extensive timeline. Additionally, the paper will focus on the use of GIS to support construction monitoring and cost reconciliation analysis. Finally, we will review preparation of final drawings, summarize lessons learned, and discuss what the future offers in enhancing pipeline-mapping productivity.

Abstract:
Many pipeline industry managers and senior officials intuitively understand that location is important to most aspects related to pipelines throughout the life-cycle — from project concept, through construction and operations and finally to decommissioning. However, many organizations are not taking full advantage of location as being a vital component to support business decision-making across the entire range of activities undertaken by pipeline companies. A Geographic Information System (GIS) is a tool that takes advantage of geography. GIS is ideally suited for the storage, display, and output of geographic data, and moreover, the analysis and modeling of geographic data. While GIS has been around as a technology for over 30 years it is only in the last several years that it has started to be extensively used within the pipeline industry. Most managers have heard about GIS. Many organizations have already started to implement GIS and CAD-based solutions through individual projects and with a technical focus of automating work flows or business processes such as generating alignment sheets, regulatory compliance, integrity management, and land management to name a few. Given that many of these applications tend to be stand-alone or isolated developments, pipeline companies need to look at the complete spatial environment of all potential tools and applications, and support this with a vision of a common spatial data warehouse in a holistic sense. Any company that embraces a continuous gathering of spatial data throughout the pipeline life-cyle will have a significant knowledge base whose value will increase over time. A spatial data warehouse of truly integrated environmental, engineering and socioeconomic factors related to a pipeline during the entire lifecycle will have a total value that transcends the value of the individual factors. The Return on Investment (ROI) of a properly developed GIS framework and spatial data warehouse looking at all operational demands and support applications will certainly be many times over the original expenditure as measured in cost savings as well as better decision making. This paper will present insights and approaches into how to properly and effectively leverage the spatial data asset and in deploying GIS throughout the enterprise. These include addressing all of the elements that are key in implementing GIS — hardware, software, data, people and methods — as well as considering some of the ROI and value-based measures for GIS success.

Abstract:
Abstract The topography of the terrain plays a major role on the galloping of the conductors in a transmission line, especially in complicated terrains. In the present work the authors try to develop relatively new approach to use the Geographic Information Systems (GIS) data of a terrain and converted it to an accurate 3D terrain model that is suitable for carrying out computational fluid dynamics (CFD) analysis. Further, the newly developed approach will be used to evaluate the contribution of the terrain to the collapse of a high voltage transmission tower near Saurdal a town in north-western part of Norway. The first part of the article describes in detail each step involved in the conversion of GIS data to 3D computed added design (CAD) model. Initially, the data of the accident site including the location details of the collapsed tower was obtained, this information was then used in google earth pro software to access the GIS information of the region around the collapsed tower. Then SketchUp software was employed to convert the GIS to modeler data, and finally Rhinoceros 3D was used to get the final 3D CAD file. The entire developed process was explained through the cases study of Saurdal. Actual weather data such as gust speed, gust direction, temperature, and snow cover on the terrain during the time of accident was obtained from five different weather stations was used to carry out a steady state CFD analysis. The results indicated a strong relation between terrain complexity, wind speed, and wind direction. The terrain was able to modify the local wind direction and local wind speed. For the Saurdal case the simulation results indicated that approximately 30 degrees deviation in angle of attack (crosswind) was observed in then local wind direction heading towards the collapsed tower. The terrain also contributed to increase in approximately 30–40% in local wind velocities compared to free stream, especially on higher altitude lands of the terrain. Finally, for the Saurdal incident, the results indicated that the combination of high strength ESE gusts, and terrain induced crosswinds may have resulted in the collapse of the tower.

The article contains research on use of open and specialized geoinformation systems to prepare students and postgraduates on specialties: 101 “Environmental Sciences”, 103 “Earth Sciences”, 122 “Computer Sciences”, 183 “Environmental Technologies”. Analysis of the most common world open geoinformation systems is done. Experience of geoinformation systems use for students and postgraduates teaching for different specialties is described. Predominant orientation towards the use of geoinformation systems in educational process is determined based on the analysis of scientific publications and curricula of the most popular Ukrainian universities. According to the authors the material that is given narrows knowledge and skills of students and postgraduates, particularly in computer modeling. It is concluded that ability of students and postgraduates to use geoinformation systems is interdisciplinary. In particular, it develops knowledge and skills in computer modeling of various processes that may arise in the further professional activity. Examples of professional issues and ways to solve them using geoinformation systems are given. Recommendations are given on the use of open and specialized geoinformation systems in the educational process. It is recommended to use both proprietary (ArcGis, MapInfo) and open GIS (uDIG, QGIS, Whitebox GAT) to teach students. Open GIS (uDIG, QGIS, Whitebox GAT) and specialized (Modular GIS Environment, GEO + CAD, GeoniCS, AISEEM) can be used to teach both students and postgraduates.
