GIS Support

Objective

CTRE supports DOT effectiveness through a variety of GIS centric efforts.

These support activities range in scope and time demands based on DOT needs. This includes developing GIS applications, creating dashboards and maintaining REST services.

Current Work Activities

On-going:

TIM Plans

• Finalizing TIM consultant guide
• Improving AGOL to query based on selecting location as well as route/milepost (requires conflating to LRS)
• Integrating TIM plans into RAMS
• This link provides a status of the TIM plans which have been digitized on the LRS. The layers which are labeled "in progress" are the routes which have been digitized. http://iowadot.maps.arcgis.com/apps/webappviewer/index.html?id=c5b4347fe0b64988b00d4d9631807cbc

Bridge Flooding

Working with David Claman and Bill Kaufman in the Office of Bridge.

Step 1) Identify vulnerable roadways/bridges. We have been updating the RIDB River Infrastructure by identifying the location which are potential flooding locations. This process involves pulling in FEMA flood maps, contours or other sources of data and identifying the roadways which are below the 100 year flood level. We are wrapping up the process to identify the vulnerable roadways by editing and adding the RIDB Structure, RIDB Low Road and the RIDB Site. We have completed identifying these locations for a majority of the state and are just cleaning up some locations which were not in the original RIDB Stream

• The current progress can be seen in the following layer on AGOL. The RIDB structures, low roads and sites have been updated across the entire state. https://iowadot.maps.arcgis.com/home/item.html?id=08a7828eb399422e88fcb2b65fd11149

Step 2) Reporting tool for impacts and predictions. Since David and Bill do not have an automated system yet for identifying impacted locations and predictions, we have started to develop an AGOL tool that David can use to input all of the information he reports to OTO and others that would populate the map with the vulnerable locations. This would is using Survey123 that David can use to easily submit information instead of reporting this information in a conference call.

• Work: We have developed the survey but need to port this over to the official version which would be on top of the River Infrastructure layer. This would just take Dan’s time to create the forms and FME process to collect and display the information on the map.
• Product: An additional layer in the AGOL map which would show the impacted bridges and estimated start and duration that could be used in the situational awareness map. This would be a good way of also dispersing the information to the districts, Mitch and others in addition to the conference calls.
• A mock up of what the survey would look like is shown in the following layer on AGOL: https://iowadot.maps.arcgis.com/home/webmap/viewer.html?useExisting=1&layers=3bca0fb67f8947f9be3216d09c86bbdf

TCP AGOL

• Currently on hold, waiting to meet with SRF to determine next steps in improving TCP AGOL
