Land Trust Service Areas

Open the Data Source: https://cicgis.org/arcgis/rest/services/NPS_Misc/Land_Trust_Service_Areas/MapServer/3 This dataset was derived from a list of land trust organizations provided by the Land Trust Alliance. The "Organization" attribute is the name of the organization. Only organizations that exist in 2024 and had all information required were included. Service areas were created by county or state boundaries from Census or HUC4, HUC8 or HUC12 boundaries from the National Hydrography Dataset. The "Extent_Type" attribute describes if the service area is a single county ("Single County"), single state ("Single State"), multiple counties ("Multiple Counties"), multiple states ("Multiple States"), single HUC4, HUC8 or HUC12 watersheds ("Single Watershed"), multiple HUC4, HUC8 or HUC12 watersheds ("Multiple Watersheds"), or Chesapeake Bay watershed or larger (CBW). "Service Area" attribute is a description of the service area, which was either directly copied from the organization’s website or determined by context from the website or other resources. The smallest boundary of a service area could only be county or HUC12, so even if the organization did not operate in a county or HUC in its entirety, it was still used as its representation (for example, a county park is represented by its county boundary than its actual park boundary). The "Email" attribute is the email contact for that organization if provided. The "DC", "DE", "MD", "NY", "PA", "VA" and "WV" attributes indicate if the organization is in that state or not. The "Address" attribute is the mailing or physical address of the organization. The "Website" attribute contains the URL to the organization's website.数据集获取地址：https://cicgis.org/arcgis/rest/services/NPS_Misc/Land_Trust_Service_Areas/MapServer/3。本数据集源自土地信托联盟（Land Trust Alliance）提供的土地信托机构名录。「机构（Organization）」属性字段为机构全称，仅收录2024年仍存续且信息完整的机构。服务范围基于美国人口普查局的县/州界，或美国国家水文数据集（National Hydrography Dataset）中的HUC4、HUC8、HUC12水文单元边界生成。「范围类型（Extent_Type）」属性用于说明服务范围的类型：可为单个县（Single County）、单个州（Single State）、多个县（Multiple Counties）、多个州（Multiple States）、单个HUC4、HUC8或HUC12流域（Single Watershed）、多个HUC4、HUC8或HUC12流域（Multiple Watersheds），或切萨皮克湾流域及更大范围（CBW）。「服务范围（Service Area）」属性为服务范围的说明文本，可直接取自机构官网，或通过官网及其他相关资源的上下文信息推导得出。服务范围的最小边界仅可为县界或HUC12水文单元边界，因此即便机构并未覆盖完整的县或HUC水文单元范围，仍以该边界作为其服务范围的表征（例如，某县级公园将以其所属县界而非实际公园边界作为表征范围）。「电子邮箱（Email）」属性为机构的联系邮箱，若机构提供了该信息则予以收录。「DC」「DE」「MD」「NY」「PA」「VA」「WV」属性字段用于标识机构是否位于对应州/特区。「地址（Address）」属性为机构的通信地址或实际办公地址。「官网（Website）」属性字段收录了机构官网的统一资源定位符（URL）。
