The algorithm traces safety seacontour and obtains obstacle areas, and then creates intelligently the shortest route by comparing spatial relations of line segments and obstacle areas.
通过追踪安全等深线，获取障碍区，然后测试线段与障碍区的空间关系来智能地搜索最短路径。

The residences were placed parallel to the elevation contour lines, between the end of the olive grove and the start of the seaside terrain, functioning as a passage from the land to the sea.
住宅与等高线平行，位于橄榄林末端和海滨地带的起点之间，作为从陆地到海洋的建筑通道。
