The Massachusetts House Legislative Districts (2012) datalayer reflects the state House of Representatives district boundaries as defined by Massachusetts General Laws, Chapter 57: Section 4. These 160 districts were those used in the elections from 2012 and prior to 2022, when they were superseded by the 2021 House Districts.Staff at the Massachusetts House of Representatives developed this layer with its contractor, Caliper Corp. (Newton, MA), using Maptitude for Redistricting software. MassGIS appended the 1:100,000 coastline and state outline and added the attribute fields. Election results are obtained from the Secretary of State.

The MassDEP Wetlands datalayer comprises two feature types, polygons and arcs (lines). The attribute codes in the polygon layer describe different types of wetland environments and the arc attributes describe line types based on adjacent polygon types or arcs defined as hydrologic connections.In this service the wetland areas are displayed using outlines and labeled with wetland code abbreviation. This symbology is useful for displaying the data atop aerial imagery.Please see https://www.mass.gov/info-details/massgis-data-massdep-wetlands-2005 for more details.

This application provides users with detailed information on hunting opportunities available on Department of Conservation and Recreation (DCR), Division of Water Supply Protection (DWSP) land in central Massachusetts. This is comprised of multiple pages that provide information (as text) and two interactive maps. The first interactive map is the Hunting Map, which provides all of the information a hunter might need to plan a successful hunt. The information in this map provides a comprehensive look at where hunting is allowed, the permits required, and the locations of features like fields and stone walls (and more!). The second interactive map is the Harvest Map, which provides hunters with information on deer harvested as part of the Quabbin Controlled Deer Hunts since 2010; this map is included for interest and informational purposes only. Learn more about each map below. For accessible PDF versions of this information, please select from one of the following options:Full Public Access Plan (PDF)Public Access Summary (PDF)Hunting Map InformationThis interactive map highlights hunting opportunities on DCR-DWSP land in central Massachusetts. The key data layers to this map are:Waterfowl Hunting Opportunities - a collection of points highlighting various waterbodies within the DWSP watersheds where waterfowl hunting is or is not allowed. For waterbodies that allow hunting, detailed information on exactly what is or is not allowed is provided in the feature pop-up, or in the attribute table record. Each feature pop-up also tells the user if trapping is allowed at a waterbody.Gates for Parking and Access - this layer shows the point locations of gates that can be used for parking or access onto DWSP lands. Depending on the type of point selected, the user will be provided with information on the number of parking spots available, a word of caution and (when available) photo(s) of the location. DCR-DWSP Lands by Permit Type - this polygon layer shows DWSP property boundaries and indicates if (and what type) of hunting is allowed in a certain area. These serve as a backdrop to all other data presented within the map. Click on a feature for more information, or review the attribute table to see what activities are allowed. Many layers in this map have a visibility constraint placed on them, and will only appear in the map as the user zooms in closer to an area. This helps ensure the map does not become cluttered when viewed at the full map extent. This map also contains numerous reference layers which provide important contextual information, such as the locations of marked intersections with labels for intersection number, locations of road and trails (with name and basic information on trail markings), locations of portable toilets, locations of Wildlife Management Areas (WMAs), hydrography, such as streams with names labeled, wetlands and lakes/ponds with names labeled and town boundaries. A group layer provides a collection of layers specifically relevant to the Quabbin Controlled Deer Hunts and includes: road barriers, marked intersections, hunt check-in locations, moose survey stations, deer check stations, and special road access.Together, this information provides a comprehensive map detailing where hunting and trapping is allowed within the DWSP watersheds and what specific hunting and trapping activities are allowed at each location. This map can help users plan a successful visit to DWSP property. When accessed through the ArcGIS Online Map Viewer, each layer's attribute table can be accessed, providing data in an alternative format. This map is also compatible with ArcGIS Field Maps and can be downloaded to "go offline", enabling a user access to the downloaded portion of the map when there is no cell service. Harvest Map InformationDeer Harvested by Weight - a collection of points showing where deer have been harvested during the Quabbin Controlled Deer Hunt within the Quabbin Reservoir Watershed. These points are symbolized to differentiate between male (dark blue circles with a light blue outline) and female (light red diamonds with a dark maroon outline) deer. DCR-DWSP Lands by Permit Type - this polygon layer shows DWSP property boundaries and indicates the type of permit required to hunt in any given area. This layer is configured to display four types of features; areas where a 5-Year Access Permit is required is shown in dark teal, areas where a Two-Day Deer Controlled Hunt Permit is required are shown in light orange, areas where a Deer Shotgun Season Controlled Hunt Permit is required are shown in bright yellow with dark yellow dots, and No Hunting Allowed areas are shown in a dark red. Click on a feature for more information, or review the attribute table to see what activities are allowed.Many layers in this map have a visibility constraint placed on them, and will only appear in the map as the user zooms in closer to an area. This helps ensure the map does not become cluttered when viewed at the full map extent. As you zoom in, these references features will appear. They provide important contextual information, such as the locations of marked intersections with labels for intersection number, locations of road and trails, hydrography, such as streams with names labeled, wetlands and lakes/ponds with names labeled.Together, this information provides a comprehensive map detailing where deer have been harvested within the Quabbin Reservoir Watershed. This map is designed for deer hunters and may help them plan where to hunt in the watershed. When accessed through the ArcGIS Online Map Viewer, each layer's attribute table can be accessed, providing data in an alternative format. This map is best used through the DCR-DWSP Hunting Map's Harvest Map page.

Boston MA city boundary including water features.

Massachusetts building outline dataset.

This is a polygon GIS data layer showing the location and extent of various sidescan, multibeam and swath bathymetry surveys conducted by the USGS, Coastal and Marine Geology Program. Outlines of individual mosaic areas were combined to create one comprehensive layer that could be used to illustrate areas surveyed by USGS/CMGP seafloor mapping programs.

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the combined single-beam and multibeam echo-sounder data and sidescan-sonar data collected in the vicinity of Edgartown Harbor, Massachusetts. During August 2008 seismic-reflection profiles (Boomer and Chirp) were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.

This data set contains MMS Planning Area outlines in ESRI Arc/Info export and Arc/View shape file formats for the MMS Atlantic Region. The use of Planning Areas makes it easier to refer to Official Protraction Diagrams (OPD) and individual blocks within a region. The digital Planning Area outlines were constructed from the block coverage by using Arc/Info's dissolve command. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact Planning Area boundaries.

This data set contains Official Protraction Diagram (OPD) outlines in ESRI Arc/Info export and Arc/View shape file formats for the MMS Atlantic Region. The use of OPD's makes it easier to refer to individual blocks within a region or planning area. Further information on the historic development of OPD's can be found in OCS Report MMS 99- 0006:Boundary Development on the Outer Continental Shelf. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact OPD boundaries. Only the paper OPD or a digital image of them serve as OFFICIAL records.
