2027 AASHTO GIS-T Symposium
AASHTO's geospatial symposium for transportation, on linear referencing, roadway inventory and agency data governance, in Boston.
AASHTO holds its Geospatial Information Systems for Transportation symposium March 30 to April 2 at the Sheraton Boston Hotel, 39 Dalton St., hosted with the Massachusetts Department of Transportation. AASHTO calls it the premier event for geospatial professionals working in transportation. Programming runs to linear referencing, roadway inventory, data governance and agency GIS practice, alongside a technology hall and special interest groups. No 2027 registration page or program is up yet.
Why it matters for the data layer
The public road network is the base layer everything else references, and GIS-T is where the people who own it argue about how it should be modeled. Linear referencing systems, ARNOLD submissions, and how a state chooses to publish its geospatial data externally are all working sessions here rather than abstractions.
If your feeds ride on a state’s road centerline network, this is where its stewards meet. Roadway data managers, MPO and local geospatial staff and their vendors spend four days on questions that most transportation conferences treat as plumbing.
