I understand how to create the border, but not how to generate these polygons inside the first one. I think I am down to use the "model" and the PyQGIS parts of QGIS but I don't know where to begin. I think I also have an optimisation issue about this problem. qgis pyqgis polyg...
How can I make one polygon from every polygons that intersects my main ( red ) polygon and also remove polygons ( all green and part of blue with yellow stripes ) under red polygon? I'm using QuantumGIS and PostGIS. I did this (in QGIS): dissolve multipart to singleparts Please te...
Move any labels manually outside of the polygon feature to automatically create leader lines. You can also move labels within a polygon to readjust them. The leader lines only show up once the label is fully outside of the polygon feature. Video Tutorial: How to Add Leader Lines to Labels ...

Add a comment 2 Answers Sorted by: 7 One idea is to convert the MeshRegion to a BoundaryMeshRegion, and then to extract the bounding polygon. Your MeshRegion: reg = MeshRegion[ { {1.,0.},{2.,0.},{3.,0.},{4.,0.},{5.,0.},{4.5,2.5},{0.5,2.5},{2.5,0.5}, {2.5,...
Yay. However, I cannot do this with the polygon layer. I can only generate the attributes and not the vertices of each point on the lines of the polygons. I'm quite familiar with QGIS in general, as well as mapshaper and one of my old school favorites ShapeToTab (h...
