Walking Trails - Dukes County_pv

These data have been compiled by the Martha's Vineyard Commission. This Island-wide network of trails has been GPSed with various GPS devices over the years. The accuracy of each trail segment does vary based on GPS device. Some Connector Roads were either on-screen digitized or imported from MassDOT or MassGIS Roads data layers. Attribution is included to indicate surface, special designation, status - managed/unmanaged, open space/conservation property the trail is associated with, etc. This dataset also contains the trails that are used in the TrailsMV App spearheaded by the Sheriff's Meadow Foundation. To view only the App trails, set a filter/definition query to [Show in TrailsMV] = yes. This is the dataset that is also used in the Walking Trails of Martha's Vineyard book published by the Vineyard Conservation Society. Lastly, this dataset is also used for the Martha's Vineyard Land Bank's 'Conservation Lands Map' brochure. To see only those trails utilized on the MVLB map, set the filter to [Show on MVLB] = yes. This online dataset is the most current. The other products were current at date of publication or last data upload to the TrailsMV App. As of 8/11/2022, this view of the trails data does not include planned trails. The MVC is grateful to the MV Island-wide Conservation Partnership for making it possible to work collaboratively to compile such an awesome trail network and freely share it with the world.本数据集由玛莎葡萄园岛委员会（Martha's Vineyard Commission，简称MVC）编制。这套覆盖全岛的步道网络多年来已通过多款GPS设备完成轨迹采集与测绘，各步道段的定位精度会因所使用的GPS设备型号不同而存在差异。部分连接道路要么通过屏幕数字化方式采集，要么源自马萨诸塞州交通部（Massachusetts Department of Transportation，简称MassDOT）或马萨诸塞州地理信息系统（MassGIS）的道路数据图层。数据集附带属性标注信息，可用于说明步道的路面材质、特殊标识、管理状态（已管理/未管理）以及其关联的开放空间或保护用地等内容。本数据集同时收录了由谢里夫梅多基金会（Sheriff's Meadow Foundation）主导开发的TrailsMV应用程序所使用的步道数据，若仅需查看该应用程序收录的步道，可设置筛选条件或定义查询为「在TrailsMV中显示」= 是。该数据集同时也是葡萄园保护协会（Vineyard Conservation Society）出版的《玛莎葡萄园岛步行步道》一书所采用的核心数据源。此外，本数据集还被用于玛莎葡萄园岛土地银行（Martha's Vineyard Land Bank，简称MVLB）的《保护用地地图》宣传手册，若仅需查看该土地银行地图中收录的步道，可设置筛选条件为「在MVLB地图中显示」= 是。本在线数据集为当前最新版本，其余衍生产品的更新时效则停留在各自的出版日期，或最后一次上传至TrailsMV应用程序的时间节点。截至2022年8月11日，本版本的步道数据暂未收录规划待建的步道。玛莎葡萄园岛委员会谨向全岛保护伙伴关系（MV Island-wide Conservation Partnership）致以诚挚谢意，感谢其促成协作编制如此优质的步道网络，并向全球免费开放共享。
