• The Massachusetts Office of Coastal Zone Management (CZM) makes a wide range of coastal and ocean data available to the public through the Massachusetts Ocean Resource Information System (MORIS). This web-based coastal mapping tool provides detailed geographic data used for ocean planning, coastal development, public safety, tourism, transportation planning, and marine environmental protection. Users can interactively view various data layers, create and share maps, and download the data for use in a Geographic Information System (GIS). While designed for coastal management professionals, MORIS can be easily used by anyone interested in these data and maps.

    CZM has also produced final map products and published and/or funded publications focusing on mapping and data management. These products are categorized by below and then listed alphabetically by title, with links to any special MORIS features in each topic area. (Note: Any views or opinions presented in publications prepared for CZM are solely those of the author[s] and do not necessarily represent those of the Massachusetts Office of Coastal Zone Management, the Executive Office of Energy and Environmental Affairs, or the Commonwealth of Massachusetts. Please see our website policies.) See CZM Publications for the full list of materials published by CZM.

    Coastal Zone Maps

    Geology, Coastal Erosion, and Flooding

    • Barrier Beach Inventory and Maps - In 1982, CZM completed a comprehensive effort to identify and delineate the 681 barrier beaches in Massachusetts and to place them on topographic maps. These data, State Designated Barrier Beaches, were made available in MORIS in 2007.
    • Coastal Inundation Scenarios in MORIS - NOAA's coastal inundation data have been added to MORIS to allow users to interactively use the sea level rise scenario data with other information such as aerial photographs, assessor maps, public facilities and infrastructure locations, and natural resource areas.
    • Shoreline Change Maps - These online and interactive maps show the changes in the Massachusetts coastline between the mid-1800s and 1994 as a result of erosion and accretion (deposition), as well as relative sea level rise.


    Ocean Planning

    Port and Harbor Planning

    • Designated Port Area (DPA) Boundary Maps - In 2011, CZM updated the boundary maps and descriptions of the DPAs in Massachusetts. (These data can also be downloaded or used to create interactive maps of the DPA boundaries in MORIS.)

    Public Access to the Coast

    • Coast Guide Online - This interactive, online mapping tool can be used to find (and find out about) coastal areas that are open to the public. It includes hundreds of sites along the Massachusetts coast—from sandy beaches to secluded coves, rocky shores, and boat ramps—owned by government agencies and major nonprofits. These sites have been mapped in Google Earth, an easy-to-use and powerful online mapping tool, where each public location is tagged with a name, owner, web link, and picture (if available). Users may use additional Google Earth offerings, such as user photos, trails, and places of interest, to create a customized map. As of spring 2013, all federal, state, and county coastal public access sites have been mapped; town and land conservation organization sites will be added as soon as possible.
    • Massachusetts Coast Guide to Boston Harbor and the North Shore - This 2004 publication includes 22 maps and nearly 400 public access sites from Salisbury to Hull, ranging from expansive parks with concession stands to small public landings and out-of-the-way spots.

    Seafloor Mapping and Seafloor Habitat Mapping

    Water Quality - No Discharge Zone and Boat Pumpout Facilities

    • Massachusetts Commercial Pumpouts - This interactive map, created with Google Maps, provides the location of boat sewage pumpout facilities for commercial vessels in coastal Massachusetts.
    • Massachusetts No Discharge Zone pdf format of Massachusetts NDZ - 2014
file size 1MB - This 2014 map shows the Massachusetts coastal waters that are officially designated as a No Discharge Zone (NDZ), where boat sewage discharge is banned.
    • Massachusetts Pumpout Locations - This interactive map, created with Google Maps, provides the location of boat sewage pumpout facilities for recreational vessels in coastal Massachusetts.


    • Aerial Orthophotographs of Coastal Massachusetts - Orthopotographs are aerial photos that are digitally corrected for distortions and other errors. Through a project completed in June 2001, CZM, NOAA’s Photogrammetry Division, and the National Geodetic Survey produced orthophotos that cover most of the coastal zone of Massachusetts.
    • CZ-Tip - There's a Map for That on Massachusetts Ocean Resource Information System - This page gives information on the Massachusetts Ocean Resource Information System (or MORIS)—a user-friendly, web-based coastal mapping tool provides that detailed geographic data on Massachusetts coastal and ocean resources—highlighting the information available for anglers, boaters, and divers; beachgoers, sightseers, and tourists; birdwatchers; homeowners, potential buyers, builders, and developers; and students.
    • Massachusetts Coastal Watersheds Map - This full-color watershed map, printed in 1994, shows the major coastal watersheds within Massachusetts and explains how activities conducted in these watersheds affect coastal waters. Hard copies are available by request.
    • Tips on How to Use the Massachusetts Ocean Resource Information System - From customizing maps to easily finding data layers, these short tips from CZM give information on maximizing MORIS.
