Massachusetts Ocean Resource Information System (MORIS)

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

MORISthe Massachusetts Ocean Resource Information Systemis an online mapping tool created by the Massachusetts Office of Coastal Zone Management (CZM), MassGIS (Bureau of Geographic Information), SeaPlan, Applied Science Associates (ASA), Charlton Galvarino, and PeopleGIS to provide spatial data pertaining to the Massachusetts coastal zone.

PLEASE NOTE: MORIS no longer allows for download of data and may inaccurately shift how data are displayed on the map. CZM is in the process of developing a plan to continue to support the delivery of geospatial data to the public.

Also note that important additional information is provided below on MORIS, data accuracy, using the tool, and citing the data.

Launch MORIS to use the tool.

Purpose of MORIS

MORIS can be used to search and display spatial data pertaining to the Massachusetts coastal zone. Users can interactively view various data layers (e.g., tide gauge stations, marine protected areas, access points, eelgrass beds, etc.) over a backdrop of aerial photographs, political boundaries, natural resources, human uses, bathymetry, or other data including Google base maps. Users can quickly create and share maps and download the actual data for use in a Geographic Information System (GIS). While designed for coastal management professionals, MORIS can be used by anyone interested in these data and maps.

MORIS is designed to:

  • Provide spatial data that are, to the extent possible, accurate, scientifically sound, and credible.
  • Provide information to decision makers, planners, and the general public that can be used to strengthen environmental policy and guide management decisions.
  • Use a collaborative, interactive process that involves a variety of partners and data sources.
  • Ensure that the data are available in an easily accessible and useful manner.

What Do I Need to Run MORIS?

MORIS is run through a web browser. At this time, the application fully works in Google Chrome, Internet Explorer, Mozilla Firefox, and Safari. The latest versions of these browsers are recommended.

The Technology Behind MORIS

MORIS is a JavaScript web application that utilizes various components of GeoExt, a JavaScript toolkit for rich mapping applications. The application is run through a client-side web browser.

MORIS pulls data through the GeoServer mapping software. GeoServer is a free, open-source, map-serving platform that serves data using Open Geospatial Consortium, Inc. (OGC) WMS and WFS formats, among others. OGC is a nonprofit, international, voluntary consensus standards organization that is leading the development of standards for geospatial- and location-based services. The GeoServer project continues to evolve and MORIS will benefit from future enhancements and bug fixes. Side Note: An advantage of serving the datalayers through GeoServer is that in addition to supplying the MORIS client, the datalayers are available to be consumed by other clients including ArcGIS and Google Earth.
