Protected and Recreational OpenSpace Polygons

The protected and recreational open space datalayer contains conservation lands and outdoor recreational facilities in Massachusetts. The associated database contains relevant information about each parcel, including ownership, level of protection, public accessibility, assessor’s map and lot numbers, and related legal interests held on the land, including conservation restrictions. Conservation and outdoor recreational facilities owned by federal, state, county, municipal, and nonprofit enterprises are included in this datalayer. Not all lands in this layer are protected in perpetuity, though nearly all have at least some level of protection. Although the initial data collection effort for this data layer has been completed, open space changes continually and this data layer is therefore considered to be under development. Additionally, due to the collaborative nature of this data collection effort, the accuracy and completeness of open space data varies across the state’s municipalities. Attributes, while comprehensive in scope, may be incomplete for many parcels. The OpenSpace dataset includes two feature classes: · this layer: Protected and Recreational OpenSpace Polygons - polygons of recreational and conservation lands as described above · a sister layer: Protected and Recreational OpenSpace Boundaries (arcs) - attributed lines that represent boundaries of the polygons The following types of land are included in the polygon datalayer: · conservation land- habitat protection with minimal recreation, such as walking trails · recreation land- outdoor facilities such as town parks, commons, playing fields, school fields, golf courses, bike paths, scout camps, and fish and game clubs. These may be privately or publicly owned facilities. · town forests · parkways - green buffers along roads, if they are a recognized conservation resource · agricultural land- land protected under an Agricultural Preservation Restriction (APR) and administered by the state Department of Agricultural Resources (DAR, formerly the Dept. of Food and Agriculture (DFA)) · aquifer protection land - not zoning overlay districts · watershed protection land - not zoning overlay districts · cemeteries - if a recognized conservation or recreation resource · forest land -- if designated as a Forest Legacy Area More information, including details for attribute codes, is available at the MassGIS metadata page for OpenSpace.: https://www.mass.gov/info-details/massgis-data-protected-and-recreational-openspace本受保护休闲开放空间数据图层（Protected and Recreational Open Space）包含马萨诸塞州境内的保护用地与户外休闲设施。配套数据库收录了各地块的相关信息，包括权属、保护等级、公共可达性、评估地图与宗地号，以及该土地上的相关法定权益（含保护地役权）。本数据图层涵盖联邦、州、郡、市政及非营利机构所有的保护用地与户外休闲设施。 本图层内并非所有土地均享有永久保护，但几乎所有土地均至少具备一定保护等级。尽管本数据图层的初始数据采集工作已完成，但开放空间处于持续变化中，因此本数据图层仍处于开发完善阶段。此外，由于本数据采集工作具有协作共建属性，全州各市政区域内的开放空间数据准确性与完整性存在差异。尽管属性字段覆盖范围较广，但多数地块的属性信息仍可能存在缺失。 本开放空间数据集包含两类要素类： · 本图层：受保护休闲开放空间面要素（Protected and Recreational OpenSpace Polygons）——即上文所述的休闲与保护用地面状要素 · 配套图层：受保护休闲开放空间边界（Protected and Recreational OpenSpace Boundaries，弧段）——用于表示面要素边界的带属性线状要素 本面状数据图层包含以下土地类型： · 保护用地：以栖息地保护为主、附带少量休闲功能的用地，例如步行道 · 休闲用地：包含各类户外设施的用地，例如市镇公园、公共绿地、运动场、校园场地、高尔夫球场、自行车道、童子军营地以及狩猎钓鱼俱乐部场地等，其权属可为公有或私有 · 市镇林地 · 道路绿带：若被认定为保护资源，则包含道路沿线的绿色缓冲带 · 农业用地：依据农业保护限制协议（Agricultural Preservation Restriction, APR）获得保护、由马萨诸塞州农业资源厅（Massachusetts Department of Agricultural Resources, DAR，前身为食品农业部Dept. of Food and Agriculture, DFA）管理的用地 · 含水层保护用地：不含区划叠加区的用地 · 流域保护用地：不含区划叠加区的用地 · 墓地：若被认定为保护或休闲资源，则纳入本图层 · 林地：若被划定为森林遗产区（Forest Legacy Area）则纳入本图层 更多信息（含属性代码详情）可查阅马萨诸塞州地理信息系统（MassGIS）开放空间元数据页面：https://www.mass.gov/info-details/massgis-data-protected-and-recreational-openspace
