The geospatial data presented here may be used to help demonstrate a project's eligibility for consideration under the Coastal and Estuarine Land Conservation Program (CELCP). Although an applicant is not required to use this geospatial data to demonstrate a project's eligibility, this data may help demonstrate that the proposed project falls within an area identified in the state's Coastal and Estuarine Land Conservation Plan (CELC Plan) as a potential "project area." Applicants may choose to make a less accurate demonstration using the map contained within the CELC Plan itself. In all cases, CZM will make the final determination of a project's eligibility.
The CELC Plan geospatial data are available in the ESRI Shapefile format for download and display within a Geographic Information System (GIS) or GIS data viewer.* A Shapefile is a data storage format that can contain the location, shape, and attributes of geographic features represented as points, lines, and polygons. Shapefiles are stored in a set of related files typically with the following file extensions: .dbf, .shx, and .shp.
* If you don't have software to display Shapefiles, ESRI's ArcExplorer software can be downloaded for free.
Below is a list of the 78 coastal communities that comprise the geographic extent of coastal and estuarine lands as defined in the CELC Plan. Follow the instructions below, to download and view the associated geospatial data for each of these cities and towns. Please read the following disclaimer and use constraints before downloading CELCP data.
The Commonwealth of Massachusetts, the Executive Office of Environmental Affairs, and the Massachusetts Office of Coastal Zone Management make no warranties as to the accuracy of these data or any associated data. Any party that relies on these data or associated data as accurate does so at his, her, or its own risk. None of the above-named parties shall be liable for any discrepancies or inaccuracies present within these data or any data associated with the Coastal and Estuarine Land Conservation Program.
This dataset was produced for the sole purpose of helping applicants demonstrate whether their project is within a "project area" identified by the CELC Plan. It is intended for application at the town level—geographic areas from several hundreds to tens of thousands of acres. The appropriate map scale for viewing the CELCP data is 1:25,000. Displaying these data at scales greater than 1:25,000 (e.g., 1:10,000) could introduce horizontal positional inaccuracies that would compound those already inherent in the data. The dataset is based on MassGIS's Land Use data and should not be mistaken for parcel-based data. Appropriate parcel data was not available for use during the development of the CELC Plan.
Development of the CELC Plan's potential "project areas" pulled together source data of varying positional accuracy, map scales, source dates, and mapping techniques. CZM recognizes the limitations of these data and has provided a fail-safe measure, described in the CELC Plan, for CELCP applicants to substantiate that their project should have been designated a potential "project area" within the CELC Plan.
By using the CELCP data referenced above, the user acknowledges that the metadata accompanying each Shapefile has been read. A copy of the metadata is also provided with each community's CELCP data.
Download and Viewing Instructions
- Click on the desired community link, and choose "Save."
- Select a location to save the file locally, and click "Save."
- Navigate to folder containing the downloaded file(s). This is typically done using Windows Explorer or My Computer.
- The downloaded file (named "town_name.exe") contains all the necessary components for the ESRI Shapefile format (.dbf, .shx, and .shp files), in addition to ancillary files relating to map projection and metadata (.prj, .txt, and .htm files).
- Extract these files by double-clicking on the town_name.exe file. Six files will be extracted and placed into the folder (town_name.dbf, town_name.prj, town_name.shp, town_name.shx, celcp_metadata.htm, celcp_metadata.txt).
- To view these maps with existing software, simply add the downloaded shape files to your map view window.
- To view these maps in ArcExplorer, open the program and select "Theme", then "Add Theme" from the menu bar.
- Navigate to the download folder and double-click on the town's shape file.
- Select the check box on the left to turn on the data layer.
- To view town boundaries, roads and other information, download these data layers from the MassGIS Website**.
** The MassGIS Website has additional geospatial data to complement a map display of the potential "project areas" included in the CELC Plan. Types of complementary geospatial data might include but are not limited to: Town Boundaries, Roads, scanned USGS Topographic Maps (DRGs), and Orthophoto Images (aerial photography).
