3D Geospatial for Transportation: Best Practices and Project Implementation Methods
The convergence of new technologies and business requirements is fostering a new wave of 3D applications. Implementing these systems in state and local agencies requires a new set of skills and knowledge that most professionals have yet to develop. This course is a great way to get started or expand your 3D know-how.
A wide range of users may create, navigate, and analyze entire metropolitan regions or a single city block within these systems. Transportation agencies are using 3D data and visualization tools to support public involvement, planning and design, construction management, emergency preparedness, and many other business practices.
This course introduces the data, systems, and processes to be considered when implementing 3D applications including Google Earth, ArcGIS Explorer, 3ds Max, and over 30 other software tools. Using extensive case studies, attendees will learn how to navigate the dizzying array of options and prepare for a sustainable 3D geospatial practice. This course is based on the 3D Geospatial course offered by URISA. The instructor for the workshop will be Tim Case of Parsons Brinckerhoff.
Blazing the Trail: The Transportation Component of Emergency Management
In this presentation, Jo Jordon of FEMA will give the students the working knowledge of how FEMA and the Federal government are organized for emergencies and how to coodinate with them. Students will learn the procedures, terminology and expectations of an EOC (Emergency Operations Center) and how it ties in with Transportation. Topics to be covered include:
- What is the difference between ?Emergency Management' and ?Emergency Response??
- The Emergency Management Cycle
- Who participates in emergency management and response ? and their roles
- ICS (the Incident Command System), why it is applied in emergency situations and by whom
- Where does geospatial technology fit in?
- Transportation as part of emergency management
- Broken Bridges, Washed-Out Roads, Constraining Culverts and Dumpsters of Debris: The PA Perspective
- Data requirements, sharing and coordination methods
- Preparation: Plans, Models, Agreements and Exercises
- The Fourth Dimension
Classroom exercises will reinforce the topics covered.
The National Geodetic Survey's CORS Network and RTK GPS
This workshop presents the National Geodetic Survey's network of GPS Continuously Operating Reference Stations (CORS), the CORS-based Online Positioning User Service (OPUS) utility, and the theory and practice of GPS Real-Time Networks (RTN). The material presented should be of interest to professionals involved in surveying, mapping, GIS, and related geospatial disciplines.
The CORS system comprises a network of about a thousand sites, each containing a geodetic-quality GPS receiver whose data are freely available via the Internet for post-processed applications. Presentation topics include the development of the CORS network, CORS applications, and CORS data access.
OPUS is an automated utility that processes submitted GPS observation data with respect to the CORS network and provides the results to the submitter via email. Various versions of OPUS will be described and demonstrated and its forthcoming enhancements presented.
There are over 40 Real-Time Networks (RTN) operating in the continental United States, with many others under development. These networks are administered by many diverse groups in the private, public and academic sectors, such as: equipment manufacturers and vendors; state DOTs; conglomerates of surveying and engineering companies; consortia of universities with regional quasi-public organizations and private firms; and almost any imagined combination thereof. Various versions of RTN technology will be explained along with the rationale for their use, especially in comparison to classical real-time positioning. The envisioned role of the NGS in support of RTN positioning will be addressed with an eye on imminent future enhancements to this exploding technology. Bill Henning & Bill Stone of the National Geodetic Survey will be our instructors.
Visualize Your Assets with HERS-ST
The HERS-ST software is an asset management decision tool used to analyze highway ?needs' for programming & planning at the State and MPO level. HERS-ST answers questions such as:
- What level of capital expenditure is justified on benefit-cost grounds?
- What user cost level will result from a given stream of investment?
- What investment level is required to achieve a certain level of performance?
- What is the cost, over 20 years, of correcting all existing and accruing highway deficiencies?
This HERS-ST workshop will provide a hands-on demonstration to the software and will focus on utilizing the decision tool's GIS capability to visualize highway infrastructures. The class will demonstrate and instruct the participant on how to utilize and display asset management data in a GIS forum.
Participants should bring their own laptops if they desire to actively participate.
Simon Lewis of ITIS, inc and Robert Mooney of the Federal Highway Administration will be the instructors for this session.
Using LIDAR Workshop: The Basics
Brian Stevens and Qian Xiao of Woolpert will be covering some of the basics about working with LIDAR data and creating digital elevation models from it. The latest in airborne laser mapping technology, this workshop will focus on the Light Detection and Ranging (LiDAR) data acquired to support the development Digital Elevation Models (DEMs) and Digital Terrain Models (DTMs). The workshop will discuss LiDAR acquisition, processing and core LiDAR formats and products.
Topics will include:
- generation of contours
- line-of-sight analysis
- volume calculations
- bare earth and non-ground data
- canopy and vegetation analysis
A sample LiDAR dataset will be provided to participants. Participants are encouraged to bring their laptops with ArcGIS 3D Analyst installed for the workshop. Short term licenses of ARCGIS and 3D Analyst will be available for free if someone doesn't already have a copy.
Geography, the Census Bureau and Transportation--Where it all Begins
The 20th anniversary of the GIS-T conference would not be complete without a workshop on the latest innovations at the Census Bureau, especially those with a transportation flavor. How many GIS-T attendees can say that they know all about the 2010 Census Local Update of Census Addresses (LUCA) Program, Participant Statistical Areas (PSA) Program or even the Master Address File / Topologically Integrated Geographic Encoding and Referencing system (MAF/TIGER) Accuracy Improvement Project? Sound exciting? Toss in a discussion of the interrelationships between the Census defined urban and urbanized areas, FHWA ?adjusted' urban and metropolitan planning areas and you have the makings of a top notch workshop. The only thing missing would be the latest developments in the preparation of your Traffic Analysis Zones (TAZs) for the Census Transportation Planning Products (CTPP) that will be coming from the new American Community Survey (ACS). Come to this workshop and you will learn about it all.
Wait! There's more. Instructors will be on hand to demonstrate a new tool that FHWA has developed for its staff and others known as HEPGIS. HEPGIS is an interactive, web-based GIS that enables users to access transportation-related geo-spatial data using their web browser. Simple navigation tools allow users to locate and zoom-in to a geographic area of interest, and to create maps showing various geographic features and themes. And it is now available to the public.
This workshop is must for the GIS analyst, manager or even casual user who wants that spatial edge. Our exciting instructors for the workshop are Michael Ratcliffe from the Census Bureau, Bruce Spear and Ed Christopher from FHWA.
Dynamics of Environmental GIS - Persuading GIS to Multitask Through Applied Technologies and Methods
Robert Fuhler of the Arkansas State Highway and Transportation Department will lead this session with a interactive discussion
environmental GIS data and how it can be used to aid the NEPA process. GIS is a science that is multi-faceted and has come to the forefront of many disciplines. One of the most dynamic and diversified is the Environmental/Planning relationship for transportation.
This workshop will be informal and discussion-based, and will delve into 1) the methodology for effective coordination and data sharing between State, Federal, Local and Private agencies; 2) The collection, portrayal and analysis of field data (the GPS/GIS relationship) and; 3) Multitasking those data into a variety of formats. There will also be examples of several successful projects developed by the Environmental Division at the Arkansas State Highway and Transportation Department.
Resources will be provided throughout the workshop to allow participants to follow-up with additional contacts after the workshop.
Implementing AJAX in Web Based Mapping Applications
In this session, we will discuss why there is so much talk about Ajax (Asynchronous JavaScript and XML). We will explain where this technology came from, how it has evolved, who is adopting it and whether it is right for your enterprise. Discussion will focus on best-practices when implementing Ajax-solutions, overall design strategies and real-world case-studies. Demonstrations will walk-through employing Ajax-based solutions in both Java and .Net. This session will be divided into two distinct parts:
Part 1 of the session will focus on the practical implications of using Ajax. The instructors will answer the following questions.
- Is it more than just a popular buzz word?
- What are the advantages of using Ajax ?
- What does it mean from the user's perspective?
- How can Ajax be leveraged in a GIS/Mapping application ?
- What is the value of the technology in business terms?
- Can deployed applications be retrofitted?
Instructors will demonstrate practical, non-technical examples to show the dramatic differences Ajax can bring to a web application.
Part 2 of the session will provide more technical information. A discussion of the available tools and implementation techniques will provide guidance to avoid common pitfalls while reaping the benefits discussed earlier in the session. Topics will include:
- The basic components of the Ajax technology
- Language specific implementations and tools
- Top 10 Ajax mistakes
- Design considerations for the typical GIS environment
- Lessons learned through multiple implementations
