8:30 a.m. Improving Asset Integrity and Reliability with 3-D Mapping
Todd Porter, Geospatial Corporation Copresenter: Linda Ward, Geospatial Corporation Keywords: 3D Mapping, location, condition, assessment, time saving, cost saving
Vertical Interest Tags: WW; ER; T; PS; E; G; M; TR; P; S; EN; DD; AI. In order to effectively maintain, rehabilitate, or install pipelines and underground infrastructure, stakeholders must identify where assets are located and manage this data effectively. Three-dimensional (3-D) locations (XYZ) of pipelines can be achieved using various technologies. These technologies can coincide with additional condition assessment tools to provide accurate pipeline positional information along with geo-referenced pipeline condition assessment data such as CCTV video, leak detection data and interior and exterior corrosion data. Once gathered, this information can be managed effectively through GIS. 3D Mobile Mapping Recent technological advancements are fueling the capability to increase GIS database accuracy, as well as the ability to acquire, update, and use that data faster than ever. Join us to explore how new GIS field data collection solutions are specifically “driving” this advancement by using a plug and play combination of sensors, including LiDAR, GNSS tracking and positioning, digital imaging and inertial measurement unit (IMU) technology. Applications include asset management, utilities, engineering, and infrastructure. Combining GIS with 3-D Laser Scanning and LiDAR to Support Alternative Energy Projects
Steven Bein, RBF Consulting Copresenter: Larry Truman, RBF Consulting Keywords: Alternatve Energy 3D GIS LiDAR 3D Laser Scanning Google Earth Solar Potential Wind Potential Electric GIS Integration
Vertical Interest Tags: PS; E; S; EN; GR; W
This presentation will cover how to leverage GIS and ground-based 3-D laser scanning and aerial LiDAR technologies to efficiently analyze and view alternative green energy projects. Using Google Earth and ArcGIS environments, we use the 3-D data for siting projects based on physical constraints and to calculate the energy potential from wind and solar. Case studies will include sites as large as 4,300 acres and as small as a single rooftop. Each attendee will take away a basic understanding of how these technologies work together and how they can be applied to green energy projects to reduce greenhouse gases and build a better future. Professional Land Surveyors and Geospatial Professionals: Building Bridges in Arizona In 2000, a small group of Arizona Professional Land Surveyors (APLS) and GIS professionals initiated a series of workshops that sought to overcome the long-standing differences between the two groups. Those dialogues eventually resulted in the APLS’s changing its bylaws in 2006 to accept GIS Professionals as full members in its Association. In short order, an APLS Geospatial Chapter was formed to address issues of mutual concern to the surveying and GIS communities. This collaboration has resulted in many successful outcomes, including recognition at a national level at events such as the ESRI User Conference, as well as articles in professional surveying newsletters and periodicals. As well, a comprehensive set of surveying standards that were applicable to GIS projects were drafted by APLS and GIS contributors, and endorsed as a statewide standard by the Arizona Geographic Information Council (AGIC). The most important accomplishment, however, was the passage of Senate Bill 1318 in 2009 that legislated AGIC as a permanent state council, with participation by land surveying professionals. In AGIC’s subsequent Strategic Plan document, the second-ranked top strength of Arizona’s geospatial community as a whole, after the passage of Senate Bill 1318, was seen to be the ability of the “…surveying and mapping community [to] communicate and collaborate”. This session discusses the details of how surveyors and GIS professionals successfully bonded together in Arizona, and how to replicate that success elsewhere. Tuesday, April 27th Mobile Mapping - The Future of Data Collection Keywords:Mobile Mapping, Data Collection, GIS Asset Management, Infrastructure Management
Vertical Interest Tags: E; EN; ER; G; WW; T; PS; P; M; TR; S; DD; AI; Traditional data collection methodologies are time consuming and labor intensive. Personnel using handheld devices travel by foot from feature to feature in or near heavily traveled roadways. Mobile mapping systems can collect all feature information in one pass of an infrastructure corridor. Speed is dramatically increased, safely is improved, and cost is significantly reduced. Infrastructure managers can quickly populate asset databases, visualize site conditions, and obtain essential information for operations and planning.
A Practical Model for an Affordable and Accurate Common Cadastre Systems are open, standards are open, and data is everywhere. But that’s kind of the problem! Data availability is increasing, but cadastre data is ‘all over the map’ so to speak. Discover how utilities, municipalities, and a provincial governement are turning to surveyors to ‘pin down’ their cadastre in a unique and mutually beneficial new model for data sharing. Breaking News Panel • 10:30 - 12:15 Keywords: geodata, creation, sharing, crowdsourcing, OpenStreetMap, Haiti, OGC, GML, KML, GeoRSS Vertical Interest Tags: E; ER; EN; G; M; P; PS; T; TR; WW; DD, II, CC, W This panel will look at new approaches to geodata creation and sharing that have emerged in the past few years, and consider how they apply to infrastructure related problems. Crowdsourcing has grown dramatically as a mechanism for creating geospatial data, and has the potential to dramatically reduce the costs associated with geodata creation and maintenance, which of course have traditionally been very high. One of the best known initiatives in this area is OpenStreetMap, and the crowdsourcing approach is also being used by a number of commercial companies including Google, TomTom and others, as well as some government agencies. Crowdsourcing has huge potential in emergency response, and the panel will include a look at how OpenStreetMap contributed enormously to the response to the Haiti earthquake. The panel will also consider approaches to sharing geodata. New lightweight standards like GeoRSS and KML have arguably done more to facilitate sharing of geodata in practice than longer standing more heavyweight standards. Techniques for making geodata accessible to search engines like Google, rather than being hidden behind portals, have also contributed to our ability to easily share data. These and other developments will be discussed by the panel. Tuesday, April 27th 11:30 a.m. Streamlined Methods to Collect and Maintain GPS and Attribute Information for Utility Assets
Savoy Yazzie, Navajo Tribal Utility Authority Copresenter: Jake Opdahl, CartoPac Field Solutions, Inc. Keywords: field data collection, GPS, mobile technology, enterprise GIS, digital data collection, ArcFM
Vertical Interest Tags: WW; E; G; M; P; S; EN; DD; AI; WM
The Navajo Tribal Utility Authority (NTUA) needed a field data collection solution that would streamline getting data in and out of the field, plus integrate into their enterprise ESRI/SDE and ArcFM GIS environment. NTUA needed to support field crews, management, and the office GIS simultaneously. The solution NTUA implemented successfully provides a more efficient and streamlined data collection process and is utilized for its water, sewer, electric, and gas assets. Total Utility Data Management
James Anspach, J.H. Anspach Consulting Keywords: Asset management subsurface utility engineering standards GPS RFID certified data
Vertical Interest Tags: WW; ER; T; PS; E; G; TR; P; S; EN; DD; AI Utility data now resides in a variety of repositories, in a variety of formats, and with highly variable reliability. The advent of cost effective accurate GPS data collection systems and open architecture GIS storage and retrieval systems now allows all the parties that construct, design, and plan utilities to fundamentally change the disjointed ways that society collects and depicts utility data. Data collection standards and pedigree information will be key success factors.
Modeling the Real World Vertical Interest Tags: WW; ER; T; PS; E; G; P; S; EN; DD; PH
Keywords: GIS, mapping, model, 3D, land development, cadastre, infrastructure, engineering, workflow
Infrastructure professionals rely heavily on cadastral data. Governments worldwide are planning thousands of new infrastructure projects to stimulate faltering economies and to repair, strengthen, and expand existing structures to avert catastrophes. Though projects will vary widely in scope and nature, planners and engineers will have one common need: information about the land. This session addresses the challenges infrastructure professionals face obtaining accurate land information, streamlining work flows, managing infrastructure information, and collaborating across distributed teams. A Look Back at Coordination Status Report on the National Geodetic Survey’s 10-Year Plan This presentation will detail the efforts of the National Geodetic Survey to enhance the quality of and availability to the high accuracy positioning elements of the National Spatial Reference System as outlined in the 10-year plan published in 2008. These include enhancements to the On Line Positioning User Service (OPUS), Gravity for the Redefinition of the American Vertical Datum (GRAV-D), and adoption of new horizontal and vertical datums for the United States to be completed by 2018. Panel Discussion: Driven by Data: Who Pays, Who Plays? In a world where digital data paid for by taxpayers is driving navigation systems and other consumer and commercial uses, what is the right balance of free vs. fee? Should cities that built the land bases used by mapping systems provide the data for free or should they be expected to at least cover their initial investment by charging a fee? And, should the fee be minimal or what the commercial market will bear? The panel will debate these and other issues related to data sharing, including Homeland Security concerns, in the context of state law in Arizona as well as on a national and international level.

8:30 a.m. Protecting Geospatial Information Processing in the Cloud
Andreas Matheus, University of the Bundeswehr Keywords: Security, Geo Web Services, GIS, Cloud Computing
Vertical Interest Tags: WW; ER; T; PS; E; G; M; TR; P; S; EN; CS; CC; W
The strength of cloud computing is that it dramatically reduces the investment costs for users, required for processing high-volume geospatial data. But in order to have confidential or even classified geospatial data processed in the cloud, service level agreements must ensure the seamless protection of the data. This paper introduces a concept to declare and enforce service level agreements preventing unauthorized use. Interpretation of Ground Subsidence from Interferometric Data Using Geospatial Techniques
Brian Sovik, AMEC Copresenter: Bibhuti Panda, AMEC Keywords: GIS, Remote Sensing, Earth Fissures, InSAR, Infrastructure, Subsidence, Geology, Flood Structures
Vertical Interest Tags: WW; T; PS; E; G; TRP; S; EN; AI; PH
Remote sensing and geographic information systems (GIS) are a powerful combination. They form a very unique perspective of the behavior of ground subsidence resulting from the decline of groundwater in alluvial aquifers. When it comes to large infrastructure in central Arizona—such as flood retarding structures—knowing what is happening on our landscape is critical. This presentation will share information about the culmination of various geospatial sciences and technologies. Products and Services of the National Geodetic Survey This presentation will provide an overview of the varied products and services of the National Oceanic and Atmospheric Administration’s National Geodetic Survey (NGS), with a focus on offerings that are of particular interest to GIS practitioners and surveyors. Topics will include GPS Continuously Operating Reference Stations (CORS), the online positioning user Service (OPUS), the Height Modernization Program, and geodetic data and software available from the NGS Web site, www.ngs.noaa.gov. Wednesday, April 28th Ground Truth: Design of Custom Coordinate Systems in the ArcGIS Environment GPS technology and direct use of electronic survey data in GIS are together driving a growing awareness of issues related to georeferencing and map projection distortion. Survey data are often intended to represent conditions “at ground”, such that distances based on map (grid) coordinates equal “true” distances on the ground. But such survey coordinate systems are often not consistent with those used for GIS, and in many cases they are not well defined. In addition, some geographic areas managed using GIS are not well represented by any existing published coordinate system, such as the Navajo Nation (which spans five State Plane zones). Wednesday, April 28th Collecting GIS /Survey Data with Mobile LiDAR and Imagery—A New Approach New technology and recent advancements in the Mobile LiDAR Mapping arena now provide both survey and GIS professionals a rapid method data collection from a moving vehicle. To understand this new technology the presentation will begin by reviewing each component that contributes to this amazing feat of three dimensional data collection. This session will review these components. Wednesday, April 28th Cloud Computing for Utility Field Inspection and Survey Work Keywords: Cloud computing benefits and pitfalls Utility inspection, maintenance, and survey work
Vertical Interest Tags: T; E; S; DD; CC
Cloud computing is the concept in which a company’s hardware, software, and data are outsourced to a third-party vendor. There are immediate benefits to such a paradigm, such as zero initial capital expenses and reduced IT operating costs. However, does this method of IT infrastructure make sense financially and technologically for today’s electric utility? This presentation reviews the benefits and pitfalls of using the cloud computing paradigm for a utility’s inspection, maintenance, and survey data. Topographic LiDAR Elevation Data Supporting Hurricane Katrina Studies LiDAR systems have been adopted as the standard tool for collecting elevation data covering large geographic regions. In this context, they are typically more accurate than previously used mapping systems. LiDAR, however, is far from perfect. Many error sources are inherent in these systems. This presentation reviews three mapping projects that were conducted for the State of Louisiana and for the US Army Corps of Engineers (USACE) in the vicinity of southeast Louisiana. These projects were used as the bases for topographic and structure elevation data supporting hydraulic model studies in the Katrina Canal Breaches Consolidated Litigation. Two of these projects were flown before Hurricane Katrina, and the third was flown in the year 2005, immediately following the Hurricane. Wednesday, April 28th Spatial Law and Policy
Greg Buehler, Open Geospatial Consortium, Inc. Copresenters: Sam Bacharach, Open Geospatial Consortium, Inc.; Kevin Pomfret; CantorArkema, P.C. Keywords: Spatial Law Policy
Vertical Interest Tags: WW; ER; T; PS; E; G; M; TR; P; S; EN; GR
In October 2009, the Geospatial Information & Technology Association (GITA) and the Open Geospatial Consortium (OGC) hosted the Emerging Technology Summit V: Spatial Law in Washington, D.C. The specific intent was to identify the legal and policy issues that will impact the growth in consumer and business applications of geospatial systems, software, and services. Geospatial Data Sharing Via the Cloud
Brad Sileo, iFactor Consulting Keywords: SaaS Online Mapping Organizational Trusts Cloud Computing Security Scalability
Vertical Interest Tags: WW; ER; T; PS; E; G; TR; P; S; EN; DD; CC; W
The increased prominence of cloud computing architectures has changed the way that business-to-business transactions occur. With the addition of mapping technologies, the cloud is becoming an increasingly valuable tool for companies that rely heavily on geospatial information to communicate with each other. This presentation will cover the main issues that companies face when deploying such solutions, including security concerns, Web services and standards, and scalability. Geospatial Dimensions of Intelligent Infrastructure: ITAG Recap Keywords: smart grid, intelligent infrastructure, Broadband for the Nation, ITAG, GITA, industry trends, SCADA, gathering systems Vertical Interest Tags: II; E; G; P; PS; T; TR; ER; S; EN; M; WW The GITA Industry Trends Analysis Group (ITAG) meets on Monday, April 26th to explore the geospatial dimensions of intelligent infrastructure for electric, gas, telecommunications, water/wastewater, public sector, transportation, and pipeline vertical markets. This session will provide a recap of the dialogue from that session, and will provide a means for continued discussions. The ITAG meeting that is the subject of this recap is tasked with helping define the concept of Intelligent Infrastructure for a variety of different vertical application areas. The recap will include an outline of case study examples from different practitioners with an idea of both challenges and successes. The bottom line focus will be on the creation of more efficient operations with time and cost savings through the application of intelligent models, feedback from sensors, and better processes. There will be time available in this session for more open dialogue and discussions. Towards an Improved Model of Deformation in the Western US Deformation in the western United States, due to tectonic forces associated with the Pacific-North American plate boundary, causes ongoing changes of the positions of points on the Earth’s surface relative to a prescribed reference frame. As a result, accurate surveying in the western US requires an equally accurate description of this deformation to allow survey measurements conducted at different epochs to be corrected for such movement. NOAA’s National Geodetic Survey (NGS) has developed the HTDP (horizontal time dependent positioning) software that enables its users to make these corrections. HTDP contains a model of the secular (continuous) velocity field for the contiguous United States (from 125W to 100W longitude and 31-36N latitude), which is determined using bi-linear interpolation from a series of grid files.
