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.

Proposal Submission Guidelines

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. We are now accepting abstracts for the in-person meeting. There is a possibility that the 2021 Symposium may transition to a virtual meeting, so we are interested in sessions that can be conducted virtually or pre-recorded. Please keep this in mind as you develop your session.

Abstracts accepted for GIS-T 2020 will be giving a higher priority when building the program.  (Small modifications from last year’s abstract may be allowed).

GIS-T encourages presentations covering completed or ongoing projects, including lessons learned. If your proposal is based on a planned or incomplete project, state this clearly in your abstract. Presenters will be given 25 minutes, and leaving 5 minutes for questions. Submit your proposal as soon as possible through our electronic submission link. 

List only those co-presenters who will be present during the conference. Please list credit for other contributors within the presentation itself.


  • Presenters and co-presenters are required to register for at least one day of the conference.
  • Presentations that do not have a presenter or co-presenter registered 10 business days prior to the conference will be canceled and replaced.
  • No preference will be given to any presenter for particular conference days.

All presentations will be posted on the Conference Web Site ( following the conference. All presenters acknowledge the GIS-T Task Force’s right to post their presentations. Presentations must be submitted in electronic format to the Symposium Moderator at the time of presentation. The presentation cannot be larger than 7MB.

GIS-T does not have a template for presenters to follow or use in the creation of presentation slides. If you have any question please contact Eric Green, Program Chair,
