I would like to generate the intersection between lines and polygons lines and polygon in QGIS 3 and extract the id number for each line. I would like to assign a red color to the resulting lines automatically. I would also like to export the results to MS Excel format.

Where is the intersection tool located in QGIS 3?

  1. The intersection tool is located under Vector --> Geoprocessing Tools --> Intersection.

  1. You can assign a color to the resulting layer after processing

  2. You can export your data to MS Excel XLSX by right clicking on the layer --- > Export ---> Save features As then choosing MS Office Open XML Spreadsheet.

  3. If you need all the above tasks to be processed automatically, you can create a model using the "Graphic Modeller" under "Processing (Menu ---> Graphic Modeller)"
