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.

The zoning boundaries map layer is an integral part of the planning data in the City of Worcester Geographic Information System. This data is used by many City Departments in case review, code enforcement, and long range planning. Planning data layers are accessed by personnel in most City departments for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on planning analysis, spatial analysis, presentation output, and review of proposed development. The zoning boundaries data layer is governed by ordinance and is only changed accordingly. The zoning data layer was digitized by L. Robert Kimball & Associates, Inc. as part of a data conversion project in 1995. Further updates have been made by the City of Worcester since that time to reflect ordinance changes.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

Massachusetts Top 20 Soils Data Layer

In an effort to provide a simple, statewide soils data layer, the Massachusetts Top 20 soils data layer is a statewide shapefile of the soil survey data that contains a single set of attributes for each soil survey map unit. The attributes provided are those soil properties or ratings that are most requested by soil survey users through the Web Soil Survey platform.

To create the shapefile, statewide gSSURGO data was downloaded from USDA’s Geospatial Data Gateway. A Soil Data Access query was used to extract certain data elements for these most-commonly requested soil properties and interpretations and exported into an excel file. This excel file was joined with the spatial data using the mukey and the resulting shapefile was exported. Descriptions for each attribute included in the shapefile is listed below.

The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea level rise (slr) and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may be accessed at: http://www.csc.noaa.gov/slr These data depict the potential inundation of coastal areas resulting from a projected 1 to 6 feet rise in sea level above current Mean Higher High Water (MHHW) conditions. The process used to produce the data can be described as a modified bathtub approach that attempts to account for both local/regional tidal variability as well as hydrological connectivity. The process uses two source datasets to derive the final inundation rasters and polygons and accompanying low-lying polygons for each iteration of sea level rise: the Digital Elevation Model (DEM) of the area and a tidal surface model that represents spatial tidal variability. The tidal model is created using the NOAA National Geodetic Survey's VDATUM datum transformation software (http://vdatum.noaa.gov) in conjunction with spatial interpolation/extrapolation methods and represents the MHHW tidal datum in orthometric values (North American Vertical Datum of 1988). The model used to produce these data does not account for erosion, subsidence, or any future changes in an area's hydrodynamics. It is simply a method to derive data in order to visualize the potential scale, not exact location, of inundation from sea level rise

The City's Zoning Ordinance and Map are tools for land-use planning. Each zone and overlay classification guides the physical development of the City through a set of requirements set forth in the City of Worcester's Zoning Ordinance as amended. As part of the planning data layers, the zoning overlay districts map layer is an integral part of the City of Worcester Geographic Information System. Planning data layers are accessed by personnel in most City departments for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on planning analysis, spatial analysis, presentation output, and review of proposed development. This feature class combines the previously separate Mixed Use Districts and Overlay Districts, with the addition of Local Historic Districts.This map data layer represents the zoning overlay districts for the City of Worcester, Massachusetts as defined by the Zoning Ordinance, Article III, as amended.OVERLAY DISTRICTS: MU: Mixed Use Development FP: Floodplain AE: Airport Environs WR: Water Resources Protection AOD: Arts Overlay District AROD: Adaptive Re-use Overlay District SPOD: Shrewsbury Street Parking Overlay District BCPOD :Blackstone Canal Parking Overlay District CPOD: Chandler Street Parking Overlay District GPOD: Grafton Street Parking Overlay District QPOD: Quinsigamond Village Parking Overlay District DSOD: Downtown/Blackstone Canal Sign Overlay District BSOD: Blackstone River Parkway Sign Overlay District USOD: Union Station View Corridor Sign Overlay District Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost

This EnviroAtlas dataset describes the block group population and the percentage of the block group population that has potential views of water bodies. A potential view of water is defined as having a body of water that is greater than 300m2 within 50m of a residential location. The residential locations are defined using the EnviroAtlas Dasymetric (2011 version) map. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas ) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

The MassDEP Tier Classified Oil and/or Hazardous Material Sites statewide point dataset contains the approximate location of oil and/or hazardous material disposal sites that have been (1) reported and (2) Tier Classified under M.G.L. Chapter 21E and the Massachusetts Contingency Plan (MCP).Location types featured in this datalayer include the approximate center of a site, the center of a building on the property where the release occurred, the source of contamination, or the location of an on-site monitoring well. For the purposes of this document, the terms “MassDEP Tier Classified oil and/or hazardous material disposal sites” and “Tier Classified Chapter 21E sites” are synonymous and are often referred to simply as “sites”.Releases of oil and/or hazardous materials are reported to the Massachusetts Department of Environmental Protection’s (MassDEP) Bureau of Waste Site Cleanup (BWSC), according to procedures established in the MCP (310 CMR 40.0000). The sites mapped in this datalayer represent only a subset of the total reported Chapter 21E sites tracked by MassDEP BWSC. Chapter 21E sites that have not yet been Tier Classified are not contained in this datalayer.More details...Map service also available.
