Regional Conservation (Parks and Open Space)

SACOG Regional Conservation Lands obtained from the California Protected Areas Database Version 2024b CPAD 2024b Database Manual SACOG provides this data on behalf of the GreenInfo Network. CPAD is made available without charge for a wide range of uses, for example, use by government agencies in planning and operations, use by private consultants in the development of plans and analyses, use by non-profit organizations and educational institutions for strategy, research, planning, management and other functions. This use includes the ability of agencies, organizations, individuals and businesses to distribute free of any charges copies of the data and to use the data on computer networks. The Regional Parks and Open Space layer represents protected land in the six-county SACOG region. This includes properties protected for preservation of natural or historic features and recreational lands. These may be under the management of government entities, non-governmental organizations, or private entities. Data ranges from street landscaping buffer to small urban parks to large national parks and forests. Every attempt has been made to align features to county assessor parcel boundaries, though in some instances the preserved area is not all of the parcel that contains it. Some of the data originated with the California Protected Areas Database (CPAD), but more features have been added based on city, county, and special district information for parks and recreational spaces, land trust acquisitions, and data from state and national government agencies. Features are described by access level (public, limited, restricted, none, etc) to the best of our ability to determine it, primary use (PRIM_USE) and secondary use (Type), manager, name and label. Note that the private or public owner of the preserved land is not listed, but rather only the entity managing it. In most cases, these are the same. Some - the American River Parkway, for example - are managed more locally, though the owner may be a state or federal agency. Additional fields include booleans for park (developed/maintained) or open space (undeveloped/wild), descriptors of the managing agency, city in which it is located, and acreage. New in this update are planned parks and greenbelts. These are only included from areas where the information could be found in parcel layers or in planning documents. These are most easily located (or excluded, if that is the goal) by searching in the ACCESS_TYP/A本数据集为萨科格（SACOG）区域保护用地数据，源自2024b版加州保护区数据库（California Protected Areas Database Version 2024b，简称CPAD 2024b）数据库手册，由SACOG代表GreenInfo网络发布。CPAD数据免费开放供多种场景使用，例如：政府机构用于规划与运营工作、私人顾问开展规划编制与分析项目、非营利组织及教育机构用于战略制定、研究、规划、管理及其他相关职能。此类使用场景还包括允许各类机构、组织、个人与企业免费分发数据副本，以及在计算机网络中使用该数据。 区域公园与开放空间图层代表SACOG六县范围内的受保护土地，涵盖为保护自然或历史风貌而设立的地块，以及休闲用地。此类用地可由政府机构、非政府组织或私人实体管理。数据覆盖范围从街道绿化缓冲区、小型城市公园，直至大型国家公园与森林均有涉及。 研发团队已尽最大努力将地物要素与县评估员的地块边界对齐，但在部分案例中，受保护区域并非包含该要素的完整地块。部分数据源自加州保护区数据库（CPAD），但新增了更多基于市、县及特别区的公园与休闲空间信息、土地信托收购数据，以及州与联邦政府机构提供的数据。 地物要素通过以下信息进行描述：可访问级别（公开、有限访问、严格限制、无访问权限等，基于尽可能准确的判定）、主要用途（PRIM_USE）与次要用途（Type）、管理主体、名称与标签。请注意，本数据未标注受保护土地的私人或公共所有者，仅列出管理该土地的实体——多数情况下二者为同一主体。例如美国河公园道（American River Parkway）这类地块，虽所有者可能为州或联邦机构，但由地方层面负责管理。 附加字段包括用于标识是否为公园（已开发/维护）或开放空间（未开发/野生）的布尔值、管理机构描述信息、所在城市，以及占地面积。本次更新新增了规划公园与绿带数据，仅收录那些可从地块图层或规划文档中获取有效信息的区域。若需快速定位或排除此类数据，可通过搜索ACCESS_TYP字段完成相关操作。
