Vicmap Property - Display View Polygon

This dataset contains polygons which cover the cities and major towns, and smaller developed areas.\n\nThese polygons are not intended to represent "built up areas", nor do they define areas available for development. They include most of the denser areas with small property polygons, but they can include larger blocks for the convenience of simplifying the boundaries.\n\nAs far as practicable they have been aligned to property boundaries, so a property is either "inside" or "outside". There are some exceptions for features such as rivers, and multi-part polygons which may have widely separated parts. \n\nThis dataset is used to create the property_view_dvp and parcel_view_dvp datasets. These datasets have a "display" column which can be used to limit the display of the property or parcel polygons to appropriate scales. These datasets can be used to improve the efficiency of web mapping.\n\nThe polygons will be updated on an occasional basis to include newly subdivided areas.

本数据集包含覆盖城市、主要城镇以及小型开发区的多边形要素（polygon）。

此类多边形要素并非用于表征"建成区"，亦未界定可开发用地的范围。

其涵盖绝大多数带有小型产权宗地多边形（property polygon）的高密度区域，同时为简化边界起见，也会纳入较大的地块区块。

在切实可行的范围内，此类多边形要素已与产权边界对齐，因此某一宗地要么完全处于面要素内部，要么完全位于外部。但存在部分例外情况，例如河流，以及可能存在多处分散区块的多部分多边形要素（multi-part polygon）。

本数据集用于生成property_view_dvp与parcel_view_dvp数据集。这两类数据集均包含"显示（display）"字段，可用于将产权或宗地多边形要素的显示范围限制在适配的比例尺下，以此提升网络地图制图的效率。

此类多边形要素将不定期进行更新，以纳入新拆分的区域。
