Bus routes on Martha's Vineyard. Each route is dissolved into one record. This files permits for easily building a legend showing unique colors for each route. However, many routes have portions that overlap with another route ...so 'seeing' all the routes simultaneously on the map is a cartographic challenge.
Attributes: 'Use' -- yes/no field. This dataset was extracted from a larger dataset. Only those routes actively used as of Feb. 2020 are included in this file. 'Sunday Service' - yes/no indicates, as of Feb 2020, if the route is in operation on Sundays. 'YrRnd Service' - yes/no indicates, as of Feb 2020, if the route operates year-round. 'Route' - respective route number.
Existing, Programmed, and Planned bike paths and bike routes on Martha's Vineyard are included in this dataset. The linear network was extracted mostly from MassDOT Year-End Road Inventory Files or on-screen digitized from aerial photos. These data are not intended for engineering purposes.
The Status Attribute includes: Existing, Programmed, and Planned. 'Programmed' are bike routes/shared use paths that have funding identified and are included on the regional Transportation Improvement Plan.
Type Attribute includes: Designated Path, Signed Route, and Designated Lane. A 'designated path' is paved and located beside the roadway. The Signed Route may occur on a road that has a narrow shoulder or no shoulder. A 'designated lane' is on a paved road that has a demarcated bike lane shoulder along the roadway.
The Tisbury zoning GIS feature layer was created from on-screen digitizing of the 'official' Tisbury Zoning map to the FY20 parcels. The GIS work was completed by the Martha's Vineyard Commission. The 'official Tisbury Zoning map' was created by Schoefield Barbini & Hone to the best of their ability based on the information they had at that time.

The MassDEP Wetlands dataset comprises two ArcGIS geodatabase feature classes:
The WETLANDSDEP_POLY layer contains polygon features delineating mapped wetland resource areas and attribute codes indicating wetland type.
The WETLANDSDEP_ARC layer was generated from the polygon features and contains arc attribute coding based on the adjacent polygons as well as arcs defined as hydrologic connections.
Together these statewide layers enhance and replace the original MassDEP wetlands layers, formerly known as DEP Wetlands (1:12,000). It should be noted that these layers provide a medium-scale representation of the wetland areas of the state and are for planning purposes only. Wetlands boundary determination for other purposes, such as the Wetlands Protection Act MA Act M.G.L. c. 131 or local bylaws must use the relevant procedures and criteria.
The original MassDEP wetlands mapping project was based on the photo-interpretation of 1:12,000, stereo color-infrared (CIR) photography, captured between 1990 and 2000, and included field verification by the MassDEP Wetlands Conservancy Program (WCP). In 2007 the MassDEP WCP began a statewide effort to assess and where necessary update the original wetlands data. The MassDEP WCP used ESRI ArcGIS Desktop software, assisted by the PurVIEW Stereo Viewing extension, to evaluate and update the original wetlands features based on photo-interpretation of 0.5m, (1:5,000) digital stereo CIR imagery statewide, captured in April 2005. No field verification was conducted on this updated 2005 wetlands data.
The 2005 WETLANDSDEP_POLY layer includes polygon features that distinguish it from its predecessor by overall changes in size and shape. In addition, new polygons have been created and original ones deleted. Many of the polygons, however, remain the same as in the original layer. All changes have been made according to the techniques described below. For the purpose of cartographic continuity, a small number of coastal polygons outside the state boundary where added based on data provided by the United States Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA).
The 2005 WETLANDSDEP_ARC layer was generated to support map display and was designed to cartographically enhance the rendering of wetland features on a base map. Arc features in this layer were generated from the wetland polygons and coding (ARC_CODE) was assigned based on the adjacent polygon types. Hydrologic connection features (ARC_CODE = 7) were then added. Where delineated, these arc features indicate an observed hydrologic connection to or between wetland polygons. Although efforts were made to be comprehensive and thorough in mapping hydrologic connections, due to the limitations of aerial photo-interpretation some areas may have been missed.
The types of updates made to the original wetland features include alteration, movement/realignment and reclassification. In some cases original wetland areas have been deleted and new areas have been added. Updates to original wetland features resulted from the following factors: changes in the natural environment due to human activity or natural causes; advances in the field of remote sensing, allowing for more refined mapping.
Edit changes to the original wetland data include:
Addition of new wetland and hydrologic connection features
Appending (expansion or realignment) of existing (original) wetland and hydrologic connection features
Reclassification of wetlands features, due to change in wetlands environment from the original classification
Movement (or shifting) of original wetland features to better match the source imagery
Deletion of original wetland or hydrologic connection features due to changes in wetlands environment or inconsistency with mapping criteria.
Please note that although efforts were made to be comprehensive and thorough in the evaluation and mapping of statewide wetland resources some areas of the state may have been missed. Many of the wetland and hydrologic connection features remain the same as in the original data. The polygon attribute SOURCE_SCALE may be used to identify areas that have been altered from the original wetlands. The SOURCE_SCALE code 5000 indicates an updated wetland area. The SOURCE_SCALE code 12000 indicates an unaltered, original wetland polygon.
Based on customer location info provided by Edgartown Wastewater Dept. the respective parcel was identified in the FY19 parcel dataset. Limited assessing attributes are included in this file.
Data are compiled by NHESP. The Martha's Vineyard Commission did 'intersect' these data with the 3-mile limit of the town boundaries so one can identify the amount of Estimated Habitat that is within a particular Dukes County town.
Estimated Habitats are for use with the Wetlands Protection Act regulations (310 CMR 10.00). The Estimated Habitats of Rare Wildlife datalayer contains polygons that are a subset of the Priority Habitats of Rare Species. They are based on occurrences of rare wetland wildlife observed within the last 25 years and documented in the NHESP database. They do not include those areas delineated as Priority Habitat for rare plants or for rare wildlife with strictly upland habitat requirements. The Estimated Habitats presented here are part of the 15th Edition of the Massachusetts Natural Heritage Atlas, and are effective beginning August 1, 2021.
For projects or activities that fall within Estimated Habitats of Rare Wildlife and that require a Notice of Intent (NOI) to be filed under the Wetlands Protection Act, proponents are required to send a copy of the NOI to the Natural Heritage & Endangered Species Program (NHESP). Please note, the Notice of Intent form allows for a streamlined joint Massachusetts Endangered Species Act/Wetlands Protection Act review, and these filings will be reviewed by the NHESP within 30 days. Applicants choosing not to file jointly will be required by the NHESP to submit a separate MESA filing, which may take up to 90 days to review. For more information, please seewww.mass.gov/dfw/nhesp/regulatory-review.
The Estimated Habitats of Rare Wildlife layer is stored in ArcSDE as ESTHAB_POLY.
Estimated Habitats were extracted from the Priority Habitats of Rare Species datalayer, which was delineated by NHESP scientists from documented observations of rare species and are based on such factors as species movements and habitat requirements. The polygons were heads-up digitized in ArcGIS 10x and referenced to the MassGIS 2019 Aerial Imagery.
Occurrence records are continually being added, updated, deleted or otherwise modified in the NHESP database. These changes are incorporated into the Estimated Habitats of Rare Wildlife datalayer every four years.
Questions about the creation of this datalayer and its use should be directed to NHESP at 508-389-6360 or natural.heritage@state.ma.us.

The Priority Habitats of Rare Species datalayer contains polygons representing the geographic extent of Habitat of state-listed rare species in Massachusetts based on observations documented within the last 25 years in the database of the Natural Heritage & Endangered Species Program (NHESP). Priority Habitat polygons are the filing trigger for project proponents, municipalities, and all others for determining whether or not a proposed project or activity must be reviewed by the NHESP for compliance with the (MESA) and its implementing regulations. Areas delineated as Priority Habitats can include wetlands, uplands, and marine habitats. The Priority Habitats presented here are part of the 15th Edition of the Massachusetts Natural Heritage Atlas, and are effective beginning August 1, 2021.
If your project or activity falls within Priority Habitat and does not meet a MESA filing exemption (321 CMR 10.14), then you must file directly with the NHESP pursuant to MESA. For more information, please see www.mass.gov/dfw/nhesp/regulatory-review.
The Priority Habitats of Rare Species datalayer is stored in ArcSDE as PRIHAB_POLY.
Priority Habitats were digitized by NHESP scientists from documented observations of state-listed rare species and are based on such factors as reported species movements and known habitat requirements. The polygons were heads-up digitized in ArcGIS 10x and referenced to the MassGIS 2019 Aerial Imagery.
Occurrence records are continually being added, updated, deleted or otherwise modified in the NHESP database. These changes are incorporated into revisions to the Priority Habitats of Rare Species datalayer every four years.
