Each digital dataset name below links to a complete datalayer description page which contains metadata and links to free data download. The date below each datalayer title on the individual description pages represents the month and year that the data first appeared in the MassGIS database or the date of the datalayer's most recent update. If additional information is needed, especially at the feature level, review the Maintenance section of the metadata or contact the agency that created the data as listed on the dataset's page.
