The USDOT Great Lakes St Lawrence Seaway Development Corporation (GLS) Office Location layer was created by the Bureau and Transportation Statistics (BTS), then approved by a GLS agency official. BTS had several meetings and email exchanges with GLS personnel and the Congressional and Public Relations Office at GLS to help understand where the GLS offices are located. After the address and location of the GLS offices were agreed upon BTS using Esri’s ArcPro 3.0.2, various fields were then added to the database schema using the “add field” function and then fill out appropriately by BTS with GLS’s guidance and ultimate approval. data is updated as deemed necessary Great Lakes St. Lawrence Seaway Development Corporation (GLS) Policy Headquarters 202-366-0091 1200 New Jersey Ave, SE W62-300 Washington DC 20590 United States GLS@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
