If two polygons share a portion of their boundaries, one output line will be generated representing the shared segment. The line direction will be arbitrary; theLEFT_FIDand theRIGHT_FIDwill be set to the left or right polygon feature IDs accordingly. ...
①面转线:polygon to line是把面的轮廓线转换为一个线对象;面转点:feature topoint是只把面对象的中心点转换为点要素;面折点转点:featurevertices to points把面的轮廓的所有的折点转化为点。②线转面:feature to polygon是把闭合线转换为面对象。线转点:feature topoint是把线的中心点转为点。线折点转为点...
converts selected polygons to single part polylines and stores them in a new shapefile. If no polygons are currently selected, all polygons in the layer are processed. Source polygons can be single part, multi-part or mixed in the layer. The output polyline attribute table will contain the...

利用“跟随要素”工具,您可以在放置注记的同时对其相对于地图中要素边的位置进行约束。采用这种方式既可以创建标准注记,也可以创建关联要素的注记。 在创建要素窗口中单击注记要素模板。 单击创建要素窗口中的跟随要素构造工具。 提示: 在创建要素窗口中单击要素模板后,将立即激活默认的构造...
In the lazy block, create a Polyline and a SimpleLineSymbol. To create the polyline, create a PolylineBuilder and then call toGeometry() on the polygon builder. More info MainScreen.kt Expand private val polylineGraphic by lazy { // Create a blue line symbol for the polyline. val polyline...
对比Shapely包:Shapely中有Point、LineString、Polygon、MultiPoint、MultiLineString、MultiPolygon、GeometryCollection,也支持从numpy的array对象创建几何对象。 Point和PointGeometry Point无空间参考信息,通常是一对点坐标,PointGeometry有空参考信息,是一个几何对象。下面的代码演示了 Point 对象如何使用PointGeometry类构造几...
