DSI – Special Plans of Construction – Expropriation Plan, sub-areas

This dataset contains the digital vector version of all contours of roasting plans associated with special construction plans. Each plan is defined by its contour. This contour concerns the geometric envelope of all containing layers of the plan. Conceptually, it has been decided to draw a buffer around any line elements that do not occur within a base to allow them to be included within the envelope contour. The plan contour layer shall include the administrative data of the plan in the attributes.本数据集收录与特种施工图纸配套的所有焙烧方案图纸的数字矢量轮廓文件。每份图纸均以其轮廓线为唯一定义依据，该轮廓线对应图纸全部所含图层的几何包络范围。从概念设计规则层面，已明确需为所有未纳入基准图层的线要素绘制缓冲区（buffer），以确保这些线要素可被包含于包络轮廓范围内。图纸轮廓图层的属性字段中应包含该图纸的管理数据。
