I don’t have a solution yet to automatically create a style for the trajectory lines layer. Ideally, the style should be a categorized renderer that assigns random colors based on the trajectory id column. But in this case, it’s not enough to just load a QML. In the meantime, I migh...

This symbol layer will be a reference for our map when we resize the polygons. Click the Add Symbol layer (+) button. A new symbol layer Simple Fill will be added. Set the Fill color to the same color as the lines and the Stroke color to be a slightly darker color. Next, open ...
For polylines and polygons the only difference would be in the rendering method: you would use:meth:`renderPolyline() <qgis.core.QgsLineSymbolLayer.renderPolyline>`which receives a list of lines, while:meth:`renderPolygon() <qgis.core.QgsFillSymbolLayer.renderPolygon>`receives a list of point...

Right-click and choose Remove Layer…. Before we proceed further, let’s save the project. QGIS allows you to save a project inside of a GeoPackage - making it very convenient to avoid managing additional files. Go to Project ‣ Save To ‣ GeoPackage…. In the Save project to ...
Added 'Lines to polygons' tool to vector menu. Added field calculator with functions like CURRENT_DATE to be used. In 2.0 full expression support has been added too greater power and control of the final labels. The map frame now contains the ability to show the extents of another map and...
I have a project that I am required to aggregate points inside polygons that have a common value. Basically having QGIS to create a buffer around those points. The dark green arrows have a unique value of 12, and I need to fit 6 of them inside a polygon. The dark blue arrows have ...
So, how to decompose the polygon by the polyline inside and get the shapefile file with each province independently? I'm a new user of QGIS. I have done the work of combine inner/outer boundaries usingMMQGIS->merge layershows like this: ...
