Cincinnati Parks and Greenspace - Open Data

ParkServe® includes a comprehensive standardized database of local parks in nearly 14,000 cities, towns and communities. Census designated urban areas were used to define where to collect and create local data for cities, towns and communities. For each city, town and community, geographic boundaries were obtained from the US Census 2010 Places geospatial dataset and associated population estimates are derived from ESRI’s 2018 Demographic Forecasts. The ParkServe® team attempted to contact each city, town and community with a request for their parks data. If no GIS data was provided, the ParkServe® team created GIS data for the place based on available resources, such as park information from municipal websites, GIS data available from counties and states, and satellite imagery. Cities, towns and communities were then emailed a link to view the park data compiled in their area to verify the boundaries and attributes of the parks in the database through our custom web-based ParkReviewer™ application. ParkServe® Data Inclusion Property eligibility criteria for ParkServe®: Publicly-owned local, state, and national parks School parks with a joint-use agreement with the local government. Considering the scale of the project, only the joint-use agreements collected through ParkScore® were used. Privately-owned parks that are managed for full public use. Examples of property types not included in ParkServe®: Golf courses, Cemeteries For field descriptions, see: https://www.tpl.org/parkserve/downloads The Trust for Public Land's mission is to create parks and protect land for people, ensuring healthy, livable communities for generations to come.

ParkServe® 包含覆盖近14000个城市、城镇与社区的本地化公园标准化综合数据库。本项目以美国人口普查局划定的都市区作为城市、城镇及社区本地数据的采集与构建范围。针对每个城市、城镇及社区，其地理边界数据均取自美国人口普查局2010年《Places》地理空间数据集，配套的人口估算数据则来源于ESRI 2018年人口预测报告。

ParkServe®项目团队曾尝试联系所有目标区域，请求其提供辖区内的公园数据。若未收到相关地理信息系统（Geographic Information System, GIS）数据，团队将依托市政官网的公园信息、州县公开的GIS数据以及卫星影像等现有资源，为对应区域构建GIS数据。随后团队会向各城市、城镇及社区发送邮件，附带可查看辖区内已汇总公园数据的链接，以便通过自研的网页端ParkReviewer™应用程序，核验数据库内公园的边界与属性信息。

ParkServe® 数据收录的地块准入标准如下：
1. 市、州及国家级公有公园；
2. 与当地政府签订共享使用协议的校园公园。鉴于项目规模，本次仅收录通过ParkScore®采集的共享使用协议相关数据；
3. 面向全体公众开放运营的私有公园。

ParkServe®未收录的地块类型示例包括：高尔夫球场、公墓。
