This dataset depicts the geographical boundaries of MARAD's nine Gateway regions. MARAD offices located within each region provide critical marine transportation outreach activities at major U.S. gateway ports located on the West, East, and Gulf coasts, as well as on the inland river system and the Great Lakes. All gateway regions contain one office except the Inland Gateway Region which has two. See https://www.maritime.dot.gov/about-us/gateway-offices/gateway-offices for more information. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529308 MARAD provides outreach activities at gateway ports. Gateway offices work with stakeholders on various projects, help to identify sources of funding, and work on environmental and community challenges in the ports and their inter-modal connections.

This layer was created to replicate the US Department of Transportation Maritime Administration (MARAD) gateway offices’ static map on MARAD’s website (https://www.maritime.dot.gov/about-us/gateway-offices/gateway-offices), using ESRI’s ArcGIS pro software. The layer was created by going through the description in each webpage for a gateway office to understand the list of States that a gateway office encompasses. If an office encompasses a portion of the State only, then the boundary details were gathered by consulting MARAD subject matter experts. Polygons were created using MARAD’s description by either snapping to the existing State boundary files from Census and/or drawing by closely following geographical boundaries such as river/lakes/locks from the Esri Hydro Reference Overlay Map Service (https://tiles.arcgis.com/tiles/P3ePLMYs2RVChkJx/arcgis/rest/services/Esri_Hydro_Reference_Overlay/MapServer). A set of tools within ArcGIS pro were used to create the Gateway layer, such as create features, edit vertices, and snapping. For the Inland Waterways Gateway (St. Louis, MO) Gateway, specifically for the area around the Columbia River that acts as the border between Washington and Oregon, a 1 mile buffer using the buffer tool in the Analysis toolbox within ArcPro, was created around the Columbia – Snake River System (CSRS) from visual identification using the ESRI Hydro Reference Overlay Map Service from the Idaho- Washington border to the Bonneville Dam. The Bonneville Dam was visually located by following the Columbia – Snake river on the basemap. Attributes for this feature layer were based on the description of each gateway office which were represented in each row with exception of the Inland Waterway Gateway. The Inland Waterway Gateway was represented as a single polygon for both the St. Louis, Missouri office and Paducah, Kentucky office as each of these offices share the polygon. MARAD subject matter experts validated and updated these polygons to match the present situation. data is updated as deemed necessary Jake Tsubota U.S. Maritime Administration (MARAD) Economist 1200 New Jersey Ave. SE Washington DC 20590 United States jake.tsubota@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
