The Gulf of Mexico Alliance is using ArcGIS Hub to share data and maps from a variety of public and private authoritative sources across the five Gulf states. Hub has provided the tools needed to create a single point of entry for users to discover, explore, and access Gulf-wide data from a variety of sources. GOMA’s Platform now includes theme maps, a data explorer, and featured tools. This presentation will include methods used to overcome a variety of challenges, as well as a way forward for expansion and community interaction using the Hub.
