Handling Data for GIS, December 2, 2020 at 1:00 PM ET at:

Join us for three GIS Online presentations on handling Data:

Mapping DOT Projects and Highway Inventory Data – An ETL Epic Journey

The Louisiana Department of Transportation and Development has a lot of data. As part of the Department’s System of Engagement project, DOTD and ESRI have embarked on a quest to eliminate silos and turn data into information. To do this, a centralized database repository was created. ETL tools have been deployed to extract data from Systems of Record, translate to a common schema, enrich the data to meet different needs, and load into the SoE database repositories to serve out as web services for desktop/web maps and apps as well as Open Data sites (two sites) for consumption.

Modeling MIRE Data Using NoSQL

NoSQL graph‐based databases are widely used in social media applications, such as Facebook and LinkedIn. But they are underutilized in the GIS industry. We will discuss how a NoSQL graph‐based database can simplify complex data modeling of real world features by storing all of the information about intersections at the node level. We will provide an overview of how DDOT (District Department of Transportation, Washington DC) and the AppGeo team leveraged the existing DDOT Linear Referencing System (LRS) based on Esri’s Roads & Highways, to develop the workflow and processing scripts to migrate this data into a NoSQL graph database (ArangoDB), and discuss how the team developed web services, safety data visualizations, interactive queries, and a web application for viewing cross‐sections.

Tracking Oklahoma’s County Certified Mileage

For ODOT to remain compliant with both State Tax Law and ARNOLD requirements, the Inventory Management Branch uses a combination of Mobile Data Collection, Interagency Cooperation, and a strong web presence to stay accurate and up to date. Utilizing ESRI’s Collector App and ArcGIS Online allows us to collaborate with Field Personnel and County Staff in real time to update new roads and get them their funds quicker than before.

After registering, you will receive a confirmation email containing information about joining the webinar.

GIS-T 2021 Is Coming!

By General No Comments

AASHTO and the GIS for Transportation Symposium Planning Committee is proud to announce that the most important meeting for the transportation GIS community is moving toward a face-to-face meeting in 2021.

Please note that while we are monitoring the situation in Minneapolis — paying particular attention to travel, and health best practices in an effort to keep attendees safe – it still may not be possible to meet face-to-face. In that case, a decision and announcement will be made in January 2021 to ensure there is enough time to make adjustments to travel plans. The virtual meeting dates will remain the same as the in-person meeting, April 19-22, 2021.

Crash Mapping and Analysis Data and System Architecture – 

Presented by Glenn Vorhees University of Wisconsin

This presentation describes a new Crash Mapping and Analysis (CMAA) application within WisTransPortal for performing map‐based visualization and analysis. The primary features of the CMAA system are daily automated mapping of crash locations from police reported locations and an open, service‐based framework for data sharing based on ESRI geo‐processing services through integration with the WisTransPortal crash data model.

Modernization of MDTransportation Authority’ Freeway Incident Traffic Management (FITM) Plan – 

Presented by Marshall L. Stevenson III, Maryland State Highway Administration, and Jesse Day, Transcend Spatial Solutions/Rizing

This presentation will focus on the technical process and benefits of transforming existing cartographic data into Esri’ Roads and Highways (R&H) and migrating the incident narrative data into a relational database for publication with Transcend’s Report Engine; FITM managers/stakeholders will be automatically notified of: Route realignments affecting detour routes or incident zones. Any changes to supplementary data maintained by MDSHA units, for example, digital message signs (DMS), truck restrictions or signalized intersections. Capital improvement projects affecting detour routes or incident zones

After registering, you will receive a confirmation email containing information about joining the webinar.

This Webinar will feature two presentations original slated for the 2020 GIS-T Symposium

Creating CIMS: The Benefits and Challenges of Bringing Different Datasets into One Place

The Corridor Investment Management Strategy (CIMS) story map is an interactive web map that brings different datasets into a single place. The map’s purpose is to provide stakeholders with a more comprehensive picture of the transportation system’s condition, and its needs and opportunities in the metro area to better inform the planning process.The development of CIMS provided insight into the challenges of bringing a wide range of external and internal datasets together; and balancing the need for providing enough information with the need for flexibility and usability. Although the tool is still in development, the promise of its benefits includes a more usable format for sharing information about the transportation system including infrastructure condition and needs, mobility needs, and multi‐modal facilities. Presented by John Zehnder, MNDOT and Norine Wilczek

Filling the Data Gaps to Improve DOT Project Delivery

In order to speed project delivery at NCDOT, the department is leveraging GIS data throughout the project delivery pipeline to inform and streamline decision making. Project ATLAS, went live in 2019 to support this streamlining, and the applications will further be enhanced to support business process improvements planned in 2020. In some cases, data that has never been available before has been created or made more widely available to inform this effort. This includes threatened and endangered species data, improved water resource data, and the holy grail; utilities data. NC has gained agreement with one of the largest power providers in the state, Duke Energy, to share data about their Right of Way and easements. This data will inform DOT project managers about utility conflicts earlier in the project lifecycle so that impacts can be mitigated and project schedules remain on time. Presented by Eric Wilson, NCDOT

U.S. DOT and AASHTO Virtual Event on the Work Zone Data Initiative

By General No Comments

U.S. DOT and AASHTO are Co-hosting a Virtual Event on Increasing Worker and Driver Safety through Access to Work Zone Data


Co-sponsored by the U.S. Department of Transportation (U.S. DOT) and the American Association of State Highway and Transportation Officials (AASHTO), this virtual event unites geographic information system (GIS) and transportation professionals in a discussion about increasing worker and driver safety through the publication and consumption of work zone data. This discussion was originally planned to take place during the 2020 GIS for Transportation (GIS-T) Symposium, which was cancelled due to the COVID-19 pandemic, but has been re-structured to occur in a virtual format. The virtual event is scheduled for May 19 from 1:00 to 2:30 pm EDT.


The U.S. DOT is working with stakeholders from across the country to develop a standard approach for collecting, organizing, and sharing data on work zones. The Work Zone Data Initiative (WZDI) was launched in response to the need for, but lack of, a reference guide or standard on how to digitally describe and communicate dynamic work zone activities that take place on roads and highways. Work zone activity data has also become critically important as our transportation environment evolves to accommodate connected and autonomous vehicles. As such, the U.S. DOT has led the creation of a voluntary Work Zone Data Exchange (WZDx), which enables sharing of current information about dynamic conditions occurring on roads (such as construction events) to help both automated driving systems and humans navigate safely and efficiently.

Attendees will learn about these initiatives, a related planned funding opportunity, the important role of GIS and digital maps, and how Work Zone Data Feeds are published and used.


This interactive virtual event will include presentations and panel discussion.

FHWA Work Zone Data Initiative (WZDI) 
Todd Peterson – Federal Highway Administration (FHWA)

FHWA is pursuing the collaborative development of a national open specification for communicating work zone activity data across enterprise IT platforms. Learn how the Work Zone Data Initiative (WZDI) is bridging organizational and jurisdictional barriers to capitalize on economies of scale to be realized from the broad deployment of open data.

Work Zone Data Exchange (WZDx): Improving Roadway Safety for Drivers and Automated Vehicles
Amy Nelson – Office of the Secretary of Transportation (OST)

The U.S. DOT led the creation of a voluntary work zone data exchange (WZDx), which enables sharing of current information about dynamic conditions occurring on roads to help both automated driving systems and humans navigate safely and efficiently. Hear updates on the WZDx project, including priorities for data exchanges and the important role of digital maps.

Maricopa County Work Zone Data Pilot Activity 
Tomas Guerra – OZ Engineering and Derald Dudley – Bureau of Transportation Statistics (BTS) 

Maricopa County has conducted internal collaboration between its Work Zone Management, ITS, and GIS / Data Management departments to establish data workflows that support generation of a WZDx-compliant feed to achieve agency operational objectives. Hear about their efforts and lessons learned.

Interactive Questions and Answers (Q&A)

Participate in an interactive questions and answers session to learn more about work zone data activities, ask questions, and share your experiences.


Register in advance for this free virtual event. After the event, a recording will be available on the Work Zone Data Exchange (WZDx) website.
