Greater Philadelphia Trails

This shapefile is intended as a master shapefile of non-Circuit trails in DVRPC's four New Jersey counties. It was compiled by DVRPC using several sources including county open data portals, PDF park and trail maps available online, and Google Maps' trails layer. Trails were corrected and verified manually using leaf-off Nearmap and Google imagery as well as PDF maps and Strava.com where aerial imagery was not sufficient. trail_name: The trail name field was inherited from individual source shapefiles and edited when necessary. Where possible, trail_name represents the official name of the trail. In the case that official names were not available, descriptive, colloquial names were added. county: This field refers to the county the trail exists in. owner: This field refers to the agency/organization responsible for the trail. surface_type: The surface_type field includes the primary surface material based on the following categories: Crushed Stone/Gravel, Dirt, Grass, Paved (includes asphalt, concrete, and other hard surfaces), Stone Dust, and Varies (in the case where a trail is composed of more than one surface material) multi_use: This field indicates whether a trail is suitable for more than one use, e.g. walking, hiking, biking, horseback riding, etc. Where possible, the width of trails was measured to determine compliance with AASHTO standards. verif_status: This field indicates whether the trail segment is fully verified. For records that were able to be verified, this field contains the value 'Verified'. For records that were not able to be verified, this field is left blank. verif_by: This refers to the individual who edited and/or verified the trail segment. verif_date: Date of verification comments_dvrpc: This field contains notes from the DVRPC planner/analyst about any issues or observations regarding the trail segment and its verification.本形状文件（shapefile）为DVRPC所辖新泽西州四县内非环线步道的主形状文件。该文件由DVRPC整合多源数据编制而成，数据来源包括各县开放数据门户、在线可获取的PDF公园与步道地图，以及谷歌地图（Google Maps）步道图层。当航空影像不足以完成校验时，工作人员将通过无叶季Nearmap影像、谷歌影像、PDF地图及Strava.com网站对步道进行手动修正与核验。 1. 步道名称（trail_name）：该字段源自各来源形状文件，必要时将进行编辑。在条件允许的情况下，将记录步道的官方名称；若无法获取官方名称，则采用描述性的通俗名称。 2. 所属县（county）：该字段标注步道所在的县。 3. 管护主体（owner）：该字段标注负责步道管护的机构或组织。 4. 步道表面类型（surface_type）：该字段标注步道的主要表层材质，分类如下：碎石/砾石、泥土、草地、铺装路面（涵盖沥青、混凝土及其他硬质路面）、石粉，以及“混合材质”（当步道由多种表层材质构成时）。 5. 多用途属性（multi_use）：该字段标注步道是否适用于多种使用场景，例如步行、徒步、骑行、马术活动等。在可行的情况下，将测量步道宽度以确认其符合美国国家公路与运输协会（AASHTO）标准。 6. 核验状态（verif_status）：该字段标注步道线段是否已完成全面核验。已完成核验的记录，该字段值为“已核验（Verified）”；未完成核验的记录，该字段留空。 7. 核验人（verif_by）：该字段标注编辑及/或核验该步道线段的人员。 8. 核验日期（verif_date）：该字段记录步道的核验日期。 9. DVRPC备注（comments_dvrpc）：该字段收录DVRPC规划师/分析师针对该步道线段及其核验工作的相关问题与观测记录。
