Massachusetts Ocean Resource Information System (MORIS)

Learn about this online data portal and mapping tool created by the Massachusetts Office of Coastal Zone Management (CZM).

The Massachusetts Ocean Resource Information System (MORIS) is CZM's official data portal. MORIS allows users to create customized maps with a variety of data layers related to the Massachusetts coastal zone and nearshore ocean, including tide gauge stations, marine protected areas, coastal access points, eelgrass beds, Massachusetts Ocean Management Plan data, and many others. In addition to making maps, MORIS users can share and print maps, download Geographic Information System (GIS) data, explore topic-specific online viewers and story maps, and find links to other mapping and coastal data resources. While geared toward coastal management professionals, MORIS can be used by anyone interested in these data and maps.

Newest MORIS Version Released in October 2022

The latest version of MORIS was launched in October 2022. One major new MORIS upgrade is the ability to directly access data from other online web services. For example, MORIS now displays Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) data directly from FEMA—so any FEMA changes to those data are seen in MORIS in real time. With this upgrade, MORIS now provides access to many more data layers, greatly adding to its utility.

The technology underlying this version of MORIS is Esri’s ArcGIS Hub, which is a configurable community engagement platform designed to help groups such as government agencies, nonprofits, and academia organize and serve geospatial data. MORIS also leverages ArcGIS Online and Portal for ArcGIS for interactive mapping, analysis, and data sharing.
