CZM Mapping and Data Management Publications

Find summaries of and links to publications developed by the Massachusetts Office of Coastal Zone Management (CZM) on a variety of mapping and data management topics.

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).

CZM has also produced final map products and published and/or funded publications focusing on mapping and data management. These products are are listed alphabetically by title under the following categories: coastal zone maps; geology, coastal erosion, and flooding; habitat; ocean planning; port and harbor planning; public access to the coast; seafloor mapping and seafloor habitat mapping; water quality (No Discharge Zone and boat pumpout facilities), and other. (Links to any special MORIS features are also provided in each topic area.) See CZM Publications for the full list of materials published by CZM.

(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.
  • Visualizing Sea Level Rise - 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.
  • Sea Level Rise and Coastal Flooding Viewer - This tool provides interactive maps of potential coastal flooding of public facilities and infrastructure based on: sea level rise scenarios, Federal Emergency Management Agency coastal flood zones, and hurricane surge models. Examples of mapped facilities include: electrical generation facilities, fire stations, hospitals, police stations, town/city halls, and wastewater treatment plants.
  • 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 mapping tool was developed by CZM for use on mobile phones and tablets, as well as desktop computers. It includes more than 1,800 sites along the Massachusetts coast that are owned by government agencies and nonprofits and open to the public—from long, sandy beaches and rocky shores to small rights-of-way and public landings.
  • 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 No Discharge Zone (PDF, 1 MB) - 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 Commercial Pumpouts - This interactive map, created with Google Maps, provides the location of boat sewage pumpout facilities for commercial vessels in coastal Massachusetts.
  • Massachusetts Pumpout Locations - This interactive map, created with Google Maps, provides the location of boat sewage pumpout facilities for recreational vessels in coastal Massachusetts.


  • CZM Grant Viewer - This interactive map provides information on these grants awarded by CZM, the Buzzards Bay National Estuary Program (BBNEP), and the Massachusetts Bays National Estuary Partnership (MassBays): CZM’s Coastal Resilience Grants and Coastal Pollutant Remediation (CPR) Grants, BBNEP grants and funding, and the MassBays Healthy Estuaries Grants. Pop-up boxes provide details on each grant award and information can be sorted by grant program, category (including Construction - Living Shoreline or Stormwater Infrastructure, Design & Permitting, Habitat Restoration, and Vulnerability Assessment), and year that mapped data are available.
  • 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.
  • 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.
