Line polygon intersection
NettetIt is easy to test whether an edge (a, b) intersects a line. Just build a line equation for your line in the following form Ax + By + C = 0 and then calculate the value Ax + By + C … Nettet1.1 Loop over the edges of PolygonA (each 2 neighbor points creating an edge - also the first and the last). 1.2 For each edge create a line equation: "y = mx + b" (given 2 points) 1.3 Collect all the point of GroupI that are placed on the line created at "1.2" 1.4 Sort the collected points by distance from the edge start point.

NettetLine segment indices of intersection points, specified as a numeric vector. Tips If the spacing between points is large, the intersections calculated by the polyxpoly function … NettetThis algorithm splits the lines in a line layer using the lines in another line layer to define the breaking points. Intersection between geometries in both layers are considered as split points. Parameters ¶ Input layer [vector: line] Line layer containing the lines to be split. Split layer [vector: line]
NettetIntersector. Computes intersections between all input features, breaking lines and polygons wherever an intersection occurs and creating nodes at those locations. Overlapping segments are reduced to one segment before being output. View Documentation Try it Free in FME Desktop.
