This project demonstrates various task automation techniques using tools like PyQGIS, the graphical modeler, ArcPy, ModelBuilder, FME, and more. I'll also share some tasks done using QGIS & ArcGis.
The goal is to split the line at each point. The challenge is that some points don't intersect the line.
To split the line, you can follow this step :
- Using QGIS :
- Use the tool "Snap geometries to layer" from the processing toolbox. You need to set the parameter as show in the image. This will create a new point layer where all the point intersect the line layer.
- Create a small buffer from point layer. Note that the layer unit is in degree.
- Convert buffer (polygon) to line : You can use the tool "Polygons to lines" from the processing Toolbox.
- Use the tool "Split with lines" from the processing toolbx. This will split Line layer every where we have a point layer (buffer --> line).
- This is the result
- Use the tool "Snap geometries to layer" from the processing toolbox. You need to set the parameter as show in the image. This will create a new point layer where all the point intersect the line layer.
- Using Graphical Modeler : You can go to the menu Processing --> Graphical modeler. The model will appear. After that you can go to Model --> Open model. You can load the model.
- Using PyQGIS : You can open the code in the python console
