Asset Infrastructure - Gate

The Gate Feature Class sits within the National Parks and Wildlife Service (NPWS) Assets Geodatabase. The Gate point layer is only indicative for locked gates and the information is not always kept up to date therefore regard all gates as locked for safety reasons.\r\n\r\nThe Assets Geodatabase is directly related to the Assets Maintenance System (AMS) which runs under SAP and contains similar fields, values and business rules. The Assets Geodatabase is the vehicle in which spatial assets are initially captured, edited and stored so that the features have coordinates and can be viewed spatially. The data is collected across the entire NSW National Parks Estate and includes some off-park features for fire management, access and mapping purposes. The spatial feature data is manually synchronised with the AMS. The two systems run side by side and are linked by an ID field. AMS is also set up to be used by other OEH Divisions eg. Botanic Gardens and Parklands and previously Marine Parks.\r\n\r\nThe database includes the following asset Feature Class types - Barrier, Bridge or Elevated Walkway, Building, Communication Equipment, Crossing, Drainage Point, Environmental Monitoring Station, Extractive industry, Facility, Fence Handrail, Fire Management Zone, Gate, Hydraulic Point, Hydraulic Storage Point, Hydraulic Valve, Irrigation System, Landing, Landing Strip, Lookout, Natural Feature, Other Structure, Parking Area, Pipe Channel Section, Power or Communication line, Power or Communication point, Sign, Step point, Stormwater Drainage Line, Surface, Survey Mark, Tower, Track Section, Treatment Disposal System, Visitor Area, Visitor Monitoring Point.\r\nDetailed documentation is available including:\r\n- Data Dictionary (internal location - P:\\Corporate\\Tools\\Information\\Assets)\r\n- Data Model\r\n- Business Rules\r\n- Functional Location and Naming Convention\r\n\r\nNote that for external supply the dataset is simplified with certain attribute fields being removed. Those fields that have a name prefixed with "d_" contain descriptions extracted from the original geodatabase domains.

闸门要素类（Feature Class）隶属于国家公园与野生动物服务局（National Parks and Wildlife Service, NPWS）的资产地理数据库（Assets Geodatabase）。该闸门点图层仅用于标示已上锁的闸门，且信息未必始终保持最新，因此出于安全考量，请将所有闸门视为上锁状态。

资产地理数据库与运行于SAP平台的资产维护系统（Assets Maintenance System, AMS）直接关联，二者拥有相似的字段、取值与业务规则。资产地理数据库是空间资产初始采集、编辑与存储的载体，可确保要素具备坐标信息并支持空间可视化展示。该数据集覆盖整个新南威尔士州（NSW）国家公园领地，同时包含部分用于火灾管理、通行保障与制图需求的园区外要素。空间要素数据需手动与资产维护系统进行同步。两套系统并行运行，并通过ID字段实现关联。资产维护系统同时也可供环境与遗产局（Office of Environment and Heritage, OEH）的其他部门使用，例如植物园与公园管理部门，此前还曾服务于海洋公园相关业务。

该数据库包含以下资产要素类类型：屏障、桥梁或高架步道、建（构）筑物、通信设备、过境点、排水点、环境监测站、采矿业设施、通用设施、围栏扶手、火灾管理区、闸门、液压点、液压存储点、液压阀、灌溉系统、停靠点、起降场、瞭望台、自然地物、其他构筑物、停车区、管渠段、电力或通信线路、电力或通信节点、标识牌、台阶点、雨水排水管线、地表、测量标志、塔楼、路段、处理处置系统、游客区域、游客监测点。

配套提供的详细文档包括：
- 数据字典（内部访问路径：P:\Corporate\Tools\Information\Assets）
- 数据模型
- 业务规则
- 功能位置与命名规范

请注意：面向外部供应的数据集已进行简化，移除了部分属性字段。名称以"d_"为前缀的字段，其内容为从原始地理数据库域中提取的描述信息。
