Government Property Index - GPI

The Government Property Index (GPI) allows the general public to view and search basic information on NSW Government-owned land and view it on a map through the NSW Planning Portal – Spatial Viewer.\r\n\r\nThe final dataset was derived through the implementation of the following inputs - \r\n\r\n- GPR \r\n\r\n- Crown Lands (DCDB)\r\n\r\n- National Parks \r\n\r\n- Land Parcels (DCDB)\r\n\r\n- Spatial Services\r\n\r\n- PlanningDB\r\n\r\n- Property (GURAS)\r\n\r\nFurthermore, there are five data fields which are in-scope for the GPI - \r\n\r\n1.\tLot / Section / Plan \r\n\r\n2.\tAddress \r\n\r\n3.\tArea\r\n\r\n4.\tZone \r\n\r\n5.\tLocal Government Area (LGA)\r\n\r\nTwo special cases are Crown Land data and National Parks data, which were obtained by ‘intersecting’ the land parcels (Lot/Section/Plan) against the Crown Land Polygon and the National Parks (Estate) Polygon respectively.\r\n\r\nThrough the combined processing of these inputs into the GPI database, the final spatial data was added onto the NSW Planning Portal – Spatial Viewer for consumption by the public.\r\n

政府财产索引（Government Property Index，GPI）允许公众通过新南威尔士州（New South Wales，NSW）规划门户——空间查看器（NSW Planning Portal – Spatial Viewer）查看、检索新南威尔士州政府所有土地的基础信息，并可在地图上进行浏览。

本最终数据集通过整合以下输入数据源构建而成：
- GPR
- 王室土地（DCDB）
- 国家公园
- 土地地块（DCDB）
- 空间服务
- 规划数据库（PlanningDB）
- 物业（GURAS）

此外，政府财产索引涵盖以下5个数据字段：
1. 地块/区段/规划图编号
2. 地址
3. 面积
4. 用地分区
5. 地方政府区域（Local Government Area，LGA）

存在两类特殊数据场景：王室土地数据与国家公园数据，二者分别通过将土地地块（地块/区段/规划图编号）与王室土地多边形、国家公园（园区）多边形进行空间相交运算得到。

通过将上述输入数据源整合处理并入库至政府财产索引数据库后，最终空间数据将被加载至新南威尔士州规划门户——空间查看器，供公众查询使用。
