Each digital dataset name below links to a complete datalayer description. On each page you will find metadata and links to free data download. The date below the datalayer name on each page represents the month and year of the most recent update (or when the data first appeared in MassGIS' database). If you need more details, especially at the feature level, you will find contact information in the Maintenance section of each page.
